Honestly, as a new guy to this stuff, I appreciated this video because it addresses some of the issues people bring up that I have not read in any literature. But they are self proclaimed experts. I don't have the knowledge to dismiss their claims so seeing this helps people like me remember that everyone thinks they're an expert until they meet a real one. Thanks Will.
Great rebuttal to these misplaced comments. So many folks are quick to correct when they have partial information. I appreciate your thorough understanding and help clarifying these folks erroneous information.
This is the perfect level of 'face planting' that our society needs more of these days. You're not being outright mean or nasty, but nor are you subscribing to the overly gentle politically correct agenda that continues to allow people to remain misinformed and thus continue to misinform others. You're a beacon of light. Keep it up!
Not only do your comments make sense from my own research, they also accord perfectly with my real world experience using this battery chemistry. You are simply doing these tests with a lot more precision. Top work. I’ve just become a fan of your channel.
Video summed up: Will: I have years of experience with various Battery chemistries, their charging cycles, cell degradation and have read into a ton of literature. Additionally I have tested countless different BMS and know exactly what to look out for. People with 5min google knowledge: „NO“
Technology enabled the know-it-all segment of society. Because, now the majority of low self-esteemed mid-wits on the planet have unfettered access to a great deal of data via the internet.
you left out he wrote a top selling book on solar power and has a website so people can get more current information. This is why I try not to make stupid comments about a subject I know nothing
Where's your data? Where are your specific references? Can you say "empirical"? Oh sorry...."years of experience"...."read into a ton"...."have tested"..."Google?" .How 'bout books published, huge numbers of followers, exploding website, try advanced degrees maybe? Yeh, rock solid data there...You have certainly sold me. Will simply does it the old fashion way. He proves it.
Very good Will! I really appreciate how you call out arrogant and cocky/disrespectful language, this type/tone of language often comes from a position of ignorance. I also like how you ask for people to show you proof that what they say is correct, shows that even with your vast knowledge in this chemistry you still have an open mind. Spot on!
Will Prowse don't let those arm chair "professionals" stir you up. I have followed your videos for a couple of years now. Your love for solar and all that goes with it is second to none.
Love seeing guys that just got into this topic because of their e-scooters and new RVs pushing back on guys that have literally lived this specific topics for years. Keep it up Will!!!
Just having built my own three 24v 120ah 8s batteries for my sprinter RV I have noticed that when floating at 28.4v then putting a load on them the voltage drops to 27.1v almost immediately ... Then it will hang there for a long time UNLESS I am running the A/C unit or I have a Large tool ie; 220v Mig Welder or my table chop saw running (Ihave a 6kw 240v invert)... but if I am just camping w/ small loads I could probable go a week of rain w/ no problems... The voltage drops some when I first enable the system but hangs at about 26.5 - 27.1 for a very long time... May I state that I am a complete novice and have built my system by watching and listening to will. The majority of my system was purchased from Electric Car Parts in Utah... (Thanks Carl) ... Will Prowst has been a godsend and his videos are pretty right on... Many Blessings , SMR
Glad you did this and explained the value & virtue of science based testing. Sad to say, but been seeing an uptick in folks that believe in what I call "conflation science" by not respecting the context. Or the crazy argument unless 100.0000% of science agrees there is a legitimate difference of opinion . For chemistry based science it is very well established and testable through microscopic physiology analysis (dendrite migration / computer chip fails). With some science there is by necessity speculation because direct testing is not possible due to scope & scale i.e. supernova's, blackholes, calibri-yau space, etc.
You’re getting so big, you’re gonna get a ton of “experts” chiming in. You’re an eccentric man which makes you so captivating and refreshing from the rest. Your methods and knowledge is sound.
Eccentric ... definately not . Will is on a mission to help people learn what he has learned . He educates himself buy fact checking and doing actual testing. If the commentors were to do what they say , they would destroy their own batteries . They are fools who would have everyone make the same mistakes as them.
Hey Will, I'm one of your forum members who bought the 280ah cells for $482 to my door from alibaba, (Xuba web site). I learned how to setup a lifepo4 battery by actually following your build guide lines carefully and my battery works great, so far, I;ve only been working on it for a few weeks. Your information is right on if you read it carefully. If there are any confusing parts of the assembly, testing and programming the forum is a big help. Setting up the BMS program is a little tricky but that is because of the poor documentation of the BMS ... it takes a little trial and error to optimize for the way I want to use it. (give up a little capacity for more charge cycles). Anyway you're a great teacher and we appreciate your hard work. jjb (aka ...tomtilly)
Hey Will, first of all: Really like your videos, how you explain things and bring the important bits and pieces to the viewer! As a doctorate student in the field of safety of lithium ion batteries, I can affirm that you do have a good understanding and structural approach on the topics. Built my own small solar farm (as a hobby the past weeks) and was lucky to find your channel, especially about some stuff where I needed more info on (MPPT vs PWM, real life data on inverters etc). For the C-rate topic: The rated nominal capacities for cells are measured for a certain current/C-rate, of course with a higher discharge current the capacity decreases slightly due to the DC-IR drop, but I think you also mentioned this. Keep it up, you're putting out great content and dont let those comments get you down!
Hi Will i am just a old bloke in Australia 62 and have found your channel to be extremely informative upfront and honest so i am a big fan of your Vid's as the older i get the Greener i am becoming so we might have something left worthwhile for the grandkids. Hope you are well, cheers
Will you rock! The minute I saw your first video, I was like: THIS GUY HAS DONE HIS HOMEWORK AND CONTINUES TO DO HIS HOMEWORK! You are humble, funny, accurate, up front but also and more importantly HONEST! People who truly follow you get what you're about, enjoy all of your work, and appreciate what you're contributing. You've taught a lot. Keep up the good work.
"You have a right to your own opinion, but not your own facts". Will - I think people underestimate your intimate knowledge and expansive knowledge on this topic. Likely because of your age. However, you have a gift to not only "Geek out" in the details, but a sign of a real expert is someone that can put complex information into Layman's terms, and we all appreciate that, especially me! Don't let ignorance upset you, the fact that you came back to disprove ("educate") may have won you new fans, since you took the time to have a conversation, which is more of what we need collectively. Thanks for all you do, Will.
I'll admit I don't know the first thing about ANYTHING you talk about. I watch because I see the passion you have for sharing your knowledge. Maybe one day it'll get through my think skull. There is nothing greater one can do in this world than to share knowledge.
Your methods are sound, proven and consistent. The findings are easily repeatable, good scientific methods applied here. I trust your findings, as I have seen your earlier videos where you have honed your methods. You are my "go to guy" for allthings solar. Keep up the good work.
I'm going to tell you strait up what I like about what you're doing. You have facts and you're not expressing an opinion, and when you do give an opinion, you say its an opinion. A fact can't be disputed. It stands on its own merits. I never argue with my opinion because my opinion is worthless. Only the facts matter. The worse thing someone can do is to try and provide credibility to their argument by telling me they are an EE. and they know what they are talking about. I will relish the opportunity to tell them they should seek compensation for their lack of an education. Disputing the manufactures recommendations and specifications isn't smart unless someone can show test data measurements that conflict with the manufactures data sheet. The only exception to this is UL laboratories safety recommendations, if there are any. They have the final word and shouldn't be ignored under any circumstances.
First: Thank you for your great work here on this channel! I learned a lot about LIFEPO4 and checked A LOT of facts from different sources! Your work is really great and don't worry about those comments.... It's usually the same all over the net! Please continue the great and very informative work of yours! thx a lot and greetings from Austria
Thank you for making this video. You have done a great job of providing useful and valuable information to your viewers who are interested in learning how to assemble solar systems with battery storage. There is no question that you know what you are doing and have put in the time and effort to learn every aspect of the chemistry as well as the safe and effective use of your tools and testing equipment. Keep up the good work and keep making great videos.
I had the impression these commenters were challenging data/testing. They are not haters. It's always good to challenge. Ask Steve Jobs? And Will, you are coming across as arrogant in this segment.
Dear i m 100 percent satisfied with ur this video...lifepo4 3.65vpar cell at max and 2.5v per cell min limit ...i have atleast 4year deep research on lithium battery
David is correct, always challenge, always question. It is good practice and it how you learn. But I also agree there is no arrogance in Will’s statements and I can think of no video he has done that he has arrogance. He explains calmly and with evidence his point of view. He also states , nicely, to go out and read the legitimate documents that are out there, which shows he wants you to prove him wrong if you can do so with scientific data. As usual Will, wonderful job.
David Sutherland the problem is the comments he responded to were pretty clearly not based in the knowledge or experience that would make them qualified to question him to begin with. If you’re going to question someone who is an expert in the field, you’d better know what you’re talking about.
10/10 video. People trying to use their Google search knowledge against a person---who I consider---that is an expert in the field. It's hilarious. The Dunning-Kruger effect at its best. Love all your videos, man...I've learned a lot.
Will you saved me literally thousands. The links from your website helped me find a deal on used 250W panels, a pallet of 10 for about 20 cents a watt. They're shipping now and I'll let ya know how it goes after setup. Even if only half work that's an order of magnitude cheaper than renogy. Bought your book on amazon as a thank you for this and all the other good info. Will post a review when it arrives. Keep up the good work and thanks again, you're really making a positive difference for a lot of folks.
Update: got the panels today and they rock. They’re not pretty but man they perform. Rated for 37.6 Voc, actual measured 31 V in 6 pm shade on a cloudy north Texas day. About $450 for a pallet of ten plus shipping. That’s 2.5 kW fellow sun warriors! Go to Wills page and follow the eBay links at the bottom.
In my 30+ year career as an aircraft controls tech and then mechanical engineer and building automation the first thing you do is ignore anyone that starts off a comment with "In my 30+ year career...." 😉 Keep kicking ass and doing what you are doing (helping us all get a little less dumb). It is greatly appreciated.
Love it. Call them out by name, and then intelligently respond to each. Most people just want to regurgitate some random bit of data that they collected from some random source...yet have no knowledge, experience, or understanding of a subject. People have lost their desire to actually learn. I come here to LEARN. When a source teaches me....then I return. 48 years old, business owner, engineering background, and still desire to learn about my field and other topics that I find interesting. Why does everyone need to be a know-it-all. Learn to LISTEN
Hey Will, let all these "experts" spill their B.S. and just ignore them. I have used this chemistry for some time and I watch your videos from time to time. Your expertise and attention to detail coupled with the clear and concise advice you give is unrivalled here on UA-cam. Keep up the good work!
Will, thank you for reading all the comments. Even the bad ones ,blasted out of the water, teach those of us that wish to learn. You have been and will continue to be the best source for unbiased info on lithium batteries on the web
We really appreciate your videos, please don't get upset by these people who clearly don't know what they are talking about. I've personally learnt a lot from your videos, it is very hard to get these cells here in Pakistan, but I still found a way to get them for my EBike as they are much safer than lithium ion. I'm running 24s1p. thank you so much for making these videos bro.
Hi Will - Nice video addressing this issue. I think some of the comments may be innocent in nature and wanting to learn, while others are made out of ignorance or even lazyness. There are so many different chemistries on the market now, it is naive to assume they all work the same. A common message I often give to my younger, less experienced engineers is READ THE DATASHEET. It is remarkable how many people disregard this basic information. Personally I really enjoy watching your videos and find them instructive. I particularly love it when you do a tear down and debunk the claims of some of these "fly by night" vendors. People seem to forget that if something is too good to be true, it usually is. Praise the good guys and call out the rats. Keep doing what your doing man, you are helping us all.
"Because we're not getting rated capacity guys what are you thinking" pulled a chuckle outa me for sure. Way to make an extremely mature and calm "stfu" video for the doubters. Keep showing us the way good sir
AnotherDayInParadise well these guys thought they were smart was the real issue 🤣 if I asked a stupid question which I have Will was so nice with his answers. I love that he can get Savage if needed 🤣🤣🤣
Ignorance is a lack of specific knowledge and is certainly appropriate in this case. Be sure you understand the meaning of the word, not the common misconception of ignorance implying low intelligence.
You tell em Will, I hate when people jump on and start babbling bullshit, and in the first few words you know that they have there battery chemistriestrys mixed up, or just have no idea what they are talking about at all!!!
I think this is a learning channel, not a trolling channel. Because of all the knowledge from this channel, I just completed my first solar setup in my van. Thanks Will.
When watching (and enjoying) your educational videos I may only understand about 10% of what you are saying, but I have complete confidence in you. Clearly you know what you are talking about and, whenever I need to learn about solar charging and batteries, I turn to you first. Thank you, Will. Keep ‘em coming!
Hello Will. Finally! A fellow with real knowledge and expertise about electrical power who is evaluating electrical devices. You are a breath of fresh air. All my life (now a septuagenarian) I've struggled to understand the basics. Michael Faraday I am not. So now my journey begins. I'll watch you videos and look into your book. Maybe I can gain enough knowledge to be proud of myself by overcoming my ignorance. I guess I should begin with your oldest video.
Hi, your are spot on with what you are saying in this video and the processes you use to test these batteries. Some people confuse lithium with lead acid and even think all lithium chemistries are the same. Ps, I am an electronic engineering that designs commercially available chargers for all different battery chemistries, thus if I was wrong about this stuff I would be in big trouble. Keep up the good work 👍
Thank you Mr. Prowse. Your videos are like condensed versions of whole books and courses in a very well prepared, produced and delivered manner. You are the go-to guy for anything solar related and batteries. It's like college level classes I can in the comfort of my home on my computer. You're a great guy for educating us and putting up with the ignorant haters that seem to troll on UA-cam.
This is one of my favorite videos, where everyone thinks they are an expert on social media and always have to be snarky about it, I love that you corrected them with the "facts" and "science", in such "anti-science", "anti-factual" or "alternate facts" times LOL thanks Will for your videos :)
I really like how your rebuttals are data driven and explained so well. No arrogance or anger on your part. Thank you for your videos. You have no idea how much they have helped me!!
@@rilufuzz OK, I didn't know that. Sorry. I just call it Li-Ion. Like when I disassembled a laptop battery, those 18650 cells had Li-Ion on them so that's why I call them that.
Will, you're proving that the saying, "a little knowledge is a dangerous thing" is alive and well. Your annoyance with the instant experts shines through in this video - good on you for responding quickly and effectively. Your videos are the best.
I love how calm he is talking down to people hahaha. Miss his voice and the long-ass streams he used to make, glad he is doing fine. Really smart guy and everyone should take his advice when it comes to lithium batteries.
Thank you for your patience, and thank you for sharing. I learn a lot from you and it comes across in your enthusiasm while you teach us. Thank you for all you do.
Oh man I find it so wrong that you had to waste time and effort to make a video like this. But good on you for doing it anyway. You are the reason I had the confidence to order my 12V DIY LiFePO4 battery kid as well. It arrived today (super excited) and tomorrow being a public holiday here in South Africa I have all day to start building and testing my new kit. Thanks so much for the information you share, Without the work you do I would not have had the confidence to invest in this kind of battery as well. So my message to you is please keep up the great work you do there are many many of us out there that highly appreciate this.
consider doing these more often. I love reading the comment section and sometimes take my info from there because they speak with such 'authority', like they're in the know.
Yeah, when you are learning you don't know what's wrong, and usually you go to the comments to try and learn more. Fortunately will DOES know what he's talking about, but it's unfortunate for people that don't know him and read wildly wrong comments like these. One thing I've learned over the years is that some people just know enough to get themselves into trouble... And they tend to be vocal trying to show off. Running around telling people to charge to wildly incorrect voltages, or bringing up irrelevant effects that can cause you to waste money on unnecessary batteries isn't something a new person can recognize.
Mahalo, I'm learning and appreciate your straight forward testing with pro and con. Totally trust your opinion. A few years ago, with wrong advice from a local solar dealer on setting up a small solar system, caused a fire in my bus. So now I do my research, double check, and remain cautious on any product on the market. Again appreciate your honesty, and knowledge on these elements and products via your testing.
don't worry about it champ, your videos are my primary resource when I need to know something about LiFePO4, BMS, Inverters or charge controllers. I think what you're seeing is a manifestation of the Dunning-Kruger effect
Will, half of northern ca without power this is a great time to put your videos on Facebook advertising for these counties without power. Hundreds of thousands of people don’t have power for the next few days. I already put your video on my Facebook the one that is DIY solar system. God Bless
Aastan Hi, Shall I feel offended? I’m from the NIckel Cadmium age.... (ROFL) And I love the school lessons from Will! I follow his video since a long time and really learned so much that I build my own Energy Storage System out of a salvaged Volkswagen Hybrid Batterie. Will, go on as you are. You do great! Regards from Germany
@@Aastan I was thinking that myself! When I ran rc cars and I bought new sub c cells to solder together you had to charge/discharge them a few times before they would put out the rated mah capacity.
If only there was a UA-camr that’s spent a large amount of time learning and testing and dedicated their channel to solar, batteries, and components that could make videos you could watch to teach all these concepts and show test results. They could provide it for free in an easy to digest way. That way people could post how he’s wrong in every way possible. Great roasting them. Some people are just ignorant but those that are arrogant deserve the roasting. Thanks for sharing all your hard work, it’s a benefit to many people.
Soooo frustrating when comments like those are made! I deal with messages and comments like that daily and I sympathize. Thanks for this video! Hopefully it inspires some to do more research before posting. Yea, 0.2C discharge rate for capacity testing is the standard for Li-ion chemistries and it’s not hard to learn that with a bit of reading.
Way to call out these people. It's amazing that they do not know the chemistry and/or discharge. Will I have to give you props on your educational info. Keep up the good work young man. Your work with this chemistry is unprecedented.
I love these videos. It's a nice way to keep people from falling for disinformation while giving the rest of us a refresher and deeper understanding of everything you've been studying and learning. Keep up the great work!
Almost. A God wouldn't have felt a need to call them out by name and would have simply addressed the misinformation. He handled it with a degree of patience and politeness, but there's still room for improvement.
Hey Will, just for your readers (not that they will really care what I have to say) I sent your links to our CTO (solar power company) and he gives you five stars, "really smart". I have worked with this CTO for over 10 years and trust his input and evaluation. You are golden.
Hi Will Thx for the vid. Being a Complete beginner with solar is confusing with all the misdirection on the subject. Having someone thoroughly knowlegable doing beginner videos is great. A separate playlist for beginners is top shelf.
Stand fast my friend against the trolls. Your chanel has tought me so much as to disregard the trolls. I have a physics background and everything you have said, done and tested it makes sense. No need to defend. You have the high ground Matey. Stand high and proud.
I been watching for over a year now, and you REALLY know your "stuff". I got interested in this topic because of one of your videos. Continued joy and success.
@wrpiii, now that you've got a year under your belt, navigate to the Endless Sphere forums. This is where actual engineers go to work on their off-duty projects. BMS design, testing using actual standardized protocols, and a couple of decades of real-world performance testing. Spending a year there will show you just how 'amateur hour' most lithium info on youtube really is.
LOL! Oh Will, this is why I love you and your channel! A young man with integrity and a genius mind who applies himself consistently to the facts and isn't afraid to call out arrogant know-nothings, by name. And we can see by the thumbs-down that you hit the mark squarely, ha! You're the only one I trust to learn about all this stuff. As always, a true and excellent teacher. Well done!!!
Haters will be haters. Ignorant haters are even worse. I doubt VERY few of your viewers have the knowledge on this chemistry as you do. You can try to teach them and SOME will learn but most haters will always be haters. I appreciate your knowledge and presentation. Keep up the good work!
So I bought a Lithium 200 amp hour battery off of Amazon for $1,300 to use with my two 200 watt panels. With 400 watts of solar and 200 amp hours of battery my van will have plenty of power 😃 . Thanks Will for the awesome information on how to set this up! My costs were less than $2k.
Incorrect these ones need soaking in water to replenish the boiled off juice from running them at low discharge, its best in salt water as this really excites the molecules into a chemical reaction.. Warning the battery may get very cold during this period so give it some love.
This cracks me up! These people need to watch and learn! You obviously know what you’re doing. I’ve watched a bunch of your videos and have learned a lot. One thing I haven’t seen you talk about is changing from lead acid to lithium in an RV and any precautions one should take and how this change will affect my ECM. My son and I are getting ready to get rid of my 4 house batteries and put in 2 new Battleborn batteries. Any advice would be appreciated or if you have covered this in a video please guide me to it, Thanks Will! I love your videos!
Nice Will, this is why I watch your work I trust your knowledge I'm a beginner and could tell the people in the comments were obviously talking about lead acid or didn't know what they were talking about I personally appreciate the amount of effort you go to to educate your subscribers on how to build, buy, and maintain a system safely for years to come. Thanks Will.
Touché Will! Henderson, NV is lucky to have you. Another smart move with climate and no state income tax. Here in Utah we could learn some things. Well I’ve got your configuration on my kitchen table and I’m buttoning up as we speak. My 400 watt panels are mounted not plugged in on my 1 1/2 inch pvc pipes ( portable stand to be used at the cabin or RV) we have 4 feet of snow on the ski resort we live on and a scheduled plan to BLM near Vegas in 30 days. You rock and my wife says your so dang cute too.
To folks who want to undertake lithium battery projects your channel has been very informative. Please do not get too concerned about bonehead comments. I would think that most people who follow your channel pay little or no attention to them. Keep up the good work!
Haters are always going to hate. Don't let it stand in your way. Your knowledge and integrity is genuine. You've taught me everything I know about lifepo4. Keep up the great work mate 👍
I like this guy more and more! Way to explain without being negative, that's more than most can accomplish. My old brain has learned a lot from you, thank you.

Finally. The trolls get called out by name and take a hit.
Well done Will Prowse, well done.
This needs to happen more often all across you tube!
Good one! 🤣🤣🤣🤣
I’m a beginner and have learned so much from Will!
Honestly, as a new guy to this stuff, I appreciated this video because it addresses some of the issues people bring up that I have not read in any literature. But they are self proclaimed experts. I don't have the knowledge to dismiss their claims so seeing this helps people like me remember that everyone thinks they're an expert until they meet a real one. Thanks Will.
Great rebuttal to these misplaced comments. So many folks are quick to correct when they have partial information. I appreciate your thorough understanding and help clarifying these folks erroneous information.
How Many you tubers call Out there commenters/subscribers? Gotta love this guy and how he is serious about what he does. No BS here!
Keep it up Will!
The calmest "AHWWW HELL NO!!!!" i ever seen, keep up the good work and research you do for the rest of us.
Yeah I was getting the vibe before the camera started rolling that he was dropping all kinds of 4 letter words and calming himself down.
S Singh 😂
This is the perfect level of 'face planting' that our society needs more of these days. You're not being outright mean or nasty, but nor are you subscribing to the overly gentle politically correct agenda that continues to allow people to remain misinformed and thus continue to misinform others. You're a beacon of light. Keep it up!
Answered with logic and reason, not emotion. Well done.
I wish I could like this comment a thousand times.
Exactly!! Love this guy even more now. Respect. No scoffing
@CW NunyaDamnBiznez Maybe it's your username.
CW NunyaDamnBiznez Sooo in your head, he is required to respond to you because you posted a trillion times demanding it? I wouldn’t
@@johnnyh4666 Will has 350,000 subs and 53,000 views on this video but this guy wants special one-on-one treatment. Some people, SMH.
Not only do your comments make sense from my own research, they also accord perfectly with my real world experience using this battery chemistry. You are simply doing these tests with a lot more precision. Top work. I’ve just become a fan of your channel.
Video summed up:
Will: I have years of experience with various Battery chemistries, their charging cycles, cell degradation and have read into a ton of literature. Additionally I have tested countless different BMS and know exactly what to look out for.
People with 5min google knowledge: „NO“
Technology enabled the know-it-all segment of society. Because, now the majority of low self-esteemed mid-wits on the planet have unfettered access to a great deal of data via the internet.
the same idiots who fall for bullshit like solar roadways and hyperloop
@@dougzook1969 Understanding and/ or filtering out useless/false information needs some skill.
you left out he wrote a top selling book on solar power and has a website so people can get more current information. This is why I try not to make stupid comments about a subject I know nothing
Where's your data? Where are your specific references? Can you say "empirical"? Oh sorry...."years of experience"...."read into a ton"...."have tested"..."Google?" .How 'bout books published, huge numbers of followers, exploding website, try advanced degrees maybe? Yeh, rock solid data there...You have certainly sold me. Will simply does it the old fashion way. He proves it.
Very good Will!
I really appreciate how you call out arrogant and cocky/disrespectful language, this type/tone of language often comes from a position of ignorance.
I also like how you ask for people to show you proof that what they say is correct, shows that even with your vast knowledge in this chemistry you still have an open mind.
Spot on!
You are so kind. That was the most gracious debunk I have every witnessed. Thank you! Civility is not dead.
Will Prowse don't let those arm chair "professionals" stir you up. I have followed your videos for a couple of years now. Your love for solar and all that goes with it is second to none.
Love seeing guys that just got into this topic because of their e-scooters and new RVs pushing back on guys that have literally lived this specific topics for years. Keep it up Will!!!
Just having built my own three 24v 120ah 8s batteries for my sprinter RV I have noticed that when floating at 28.4v then putting a load on them the voltage drops to 27.1v almost immediately ... Then it will hang there for a long time UNLESS I am running the A/C unit or I have a Large tool ie; 220v Mig Welder or my table chop saw running (Ihave a 6kw 240v invert)... but if I am just camping w/ small loads I could probable go a week of rain w/ no problems... The voltage drops some when I first enable the system but hangs at about 26.5 - 27.1 for a very long time... May I state that I am a complete novice and have built my system by watching and listening to will. The majority of my system was purchased from Electric Car Parts in Utah... (Thanks Carl) ... Will Prowst has been a godsend and his videos are pretty right on... Many Blessings , SMR
Glad you did this and explained the value & virtue of science based testing. Sad to say, but been seeing an uptick in folks that believe in what I call "conflation science" by not respecting the context. Or the crazy argument unless 100.0000% of science agrees there is a legitimate difference of opinion . For chemistry based science it is very well established and testable through microscopic physiology analysis (dendrite migration / computer chip fails). With some science there is by necessity speculation because direct testing is not possible due to scope & scale i.e. supernova's, blackholes, calibri-yau space, etc.
You’re getting so big, you’re gonna get a ton of “experts” chiming in. You’re an eccentric man which makes you so captivating and refreshing from the rest. Your methods and knowledge is sound.
Douglas Harley, Please.
Eccentric ... definately not .
Will is on a mission to help people learn what he has learned . He educates himself buy fact checking and doing actual testing.
If the commentors were to do what they say , they would destroy their own batteries . They are fools who would have everyone make the same mistakes as them.
Eccentric?? No way! He's smart, articulate, and enthusiastic; not eccentric. He is my "go to" expert on the topics that he covers.
Hey Will, I'm one of your forum members who bought the 280ah cells for $482 to my door from alibaba, (Xuba web site). I learned how to setup a lifepo4 battery by actually following your build guide lines carefully and my battery works great, so far, I;ve only been working on it for a few weeks. Your information is right on if you read it carefully. If there are any confusing parts of the assembly, testing and programming the forum is a big help. Setting up the BMS program is a little tricky but that is because of the poor documentation of the BMS ... it takes a little trial and error to optimize for the way I want to use it. (give up a little capacity for more charge cycles). Anyway you're a great teacher and we appreciate your hard work.
jjb (aka ...tomtilly)
Hey Will, first of all: Really like your videos, how you explain things and bring the important bits and pieces to the viewer! As a doctorate student in the field of safety of lithium ion batteries, I can affirm that you do have a good understanding and structural approach on the topics. Built my own small solar farm (as a hobby the past weeks) and was lucky to find your channel, especially about some stuff where I needed more info on (MPPT vs PWM, real life data on inverters etc). For the C-rate topic: The rated nominal capacities for cells are measured for a certain current/C-rate, of course with a higher discharge current the capacity decreases slightly due to the DC-IR drop, but I think you also mentioned this.
Keep it up, you're putting out great content and dont let those comments get you down!
Hi Will i am just a old bloke in Australia 62 and have found your channel to be extremely informative upfront and honest so i am a big fan of your Vid's as the older i get the Greener i am becoming so we might have something left worthwhile for the grandkids. Hope you are well, cheers
Will you rock! The minute I saw your first video, I was like: THIS GUY HAS DONE HIS HOMEWORK AND CONTINUES TO DO HIS HOMEWORK! You are humble, funny, accurate, up front but also and more importantly HONEST! People who truly follow you get what you're about, enjoy all of your work, and appreciate what you're contributing. You've taught a lot. Keep up the good work.
"You have a right to your own opinion, but not your own facts". Will - I think people underestimate your intimate knowledge and expansive knowledge on this topic. Likely because of your age. However, you have a gift to not only "Geek out" in the details, but a sign of a real expert is someone that can put complex information into Layman's terms, and we all appreciate that, especially me! Don't let ignorance upset you, the fact that you came back to disprove ("educate") may have won you new fans, since you took the time to have a conversation, which is more of what we need collectively. Thanks for all you do, Will.
wow, right off the top name-checking ignorant viewers. gotta love this guy. 😀
I'll admit I don't know the first thing about ANYTHING you talk about. I watch because I see the passion you have for sharing your knowledge. Maybe one day it'll get through my think skull. There is nothing greater one can do in this world than to share knowledge.
Your methods are sound, proven and consistent. The findings are easily repeatable, good scientific methods applied here.
I trust your findings, as I have seen your earlier videos where you have honed your methods.
You are my "go to guy" for allthings solar.
Keep up the good work.
I don’t know why anyone would question Will’s battery Prowess! Your presentation and knowledge is obviously NOT superficial. Keep it up Will.
I'm going to tell you strait up what I like about what you're doing. You have facts and you're not expressing an opinion, and when you do give an opinion, you say its an opinion. A fact can't be disputed. It stands on its own merits. I never argue with my opinion because my opinion is worthless. Only the facts matter. The worse thing someone can do is to try and provide credibility to their argument by telling me they are an EE. and they know what they are talking about. I will relish the opportunity to tell them they should seek compensation for their lack of an education. Disputing the manufactures recommendations and specifications isn't smart unless someone can show test data measurements that conflict with the manufactures data sheet. The only exception to this is UL laboratories safety recommendations, if there are any. They have the final word and shouldn't be ignored under any circumstances.
Will, I love your videos and your attitude, don't let anyone with less or No knowledge ruin your day. Thanks for your teachings.
First: Thank you for your great work here on this channel! I learned a lot about LIFEPO4 and checked A LOT of facts from different sources! Your work is really great and don't worry about those comments.... It's usually the same all over the net! Please continue the great and very informative work of yours! thx a lot and greetings from Austria
Thank you for making this video. You have done a great job of providing useful and valuable information to your viewers who are interested in learning how to assemble solar systems with battery storage. There is no question that you know what you are doing and have put in the time and effort to learn every aspect of the chemistry as well as the safe and effective use of your tools and testing equipment. Keep up the good work and keep making great videos.
Will dont let the haters get to you when you get this big the bigger the haters
I had the impression these commenters were challenging data/testing. They are not haters. It's always good to challenge. Ask Steve Jobs? And Will, you are coming across as arrogant in this segment.
Dear i m 100 percent satisfied with ur this video...lifepo4 3.65vpar cell at max and 2.5v per cell min limit ...i have atleast 4year deep research on lithium battery
David is correct, always challenge, always question. It is good practice and it how you learn. But I also agree there is no arrogance in Will’s statements and I can think of no video he has done that he has arrogance. He explains calmly and with evidence his point of view. He also states , nicely, to go out and read the legitimate documents that are out there, which shows he wants you to prove him wrong if you can do so with scientific data. As usual Will, wonderful job.
@TRUST CHRIST OR GO TO HELL! Grow Up!
David Sutherland the problem is the comments he responded to were pretty clearly not based in the knowledge or experience that would make them qualified to question him to begin with. If you’re going to question someone who is an expert in the field, you’d better know what you’re talking about.
10/10 video.
People trying to use their Google search knowledge against a person---who I consider---that is an expert in the field. It's hilarious. The Dunning-Kruger effect at its best.
Love all your videos, man...I've learned a lot.
Will you saved me literally thousands. The links from your website helped me find a deal on used 250W panels, a pallet of 10 for about 20 cents a watt. They're shipping now and I'll let ya know how it goes after setup. Even if only half work that's an order of magnitude cheaper than renogy. Bought your book on amazon as a thank you for this and all the other good info. Will post a review when it arrives. Keep up the good work and thanks again, you're really making a positive difference for a lot of folks.
Update: got the panels today and they rock. They’re not pretty but man they perform. Rated for 37.6 Voc, actual measured 31 V in 6 pm shade on a cloudy north Texas day. About $450 for a pallet of ten plus shipping. That’s 2.5 kW fellow sun warriors! Go to Wills page and follow the eBay links at the bottom.
In my 30+ year career as an aircraft controls tech and then mechanical engineer and building automation the first thing you do is ignore anyone that starts off a comment with "In my 30+ year career...." 😉
Keep kicking ass and doing what you are doing (helping us all get a little less dumb). It is greatly appreciated.
The 55 dislikes on your video so far are the ones that got taken to school! Amazing job explaining and educating us with FACTS 👍✌😁
Love it. Call them out by name, and then intelligently respond to each. Most people just want to regurgitate some random bit of data that they collected from some random source...yet have no knowledge, experience, or understanding of a subject. People have lost their desire to actually learn.
I come here to LEARN. When a source teaches me....then I return. 48 years old, business owner, engineering background, and still desire to learn about my field and other topics that I find interesting. Why does everyone need to be a know-it-all. Learn to LISTEN
"Please Substantiate Your Claims With Evidence" - Will Prowse, September 2020 - Amen Will, amen!
Hey Will, let all these "experts" spill their B.S. and just ignore them. I have used this chemistry for some time and I watch your videos from time to time. Your expertise and attention to detail coupled with the clear and concise advice you give is unrivalled here on UA-cam. Keep up the good work!
Will, thank you for reading all the comments. Even the bad ones ,blasted out of the water, teach those of us that wish to learn. You have been and will continue to be the best source for unbiased info on lithium batteries on the web
We really appreciate your videos, please don't get upset by these people who clearly don't know what they are talking about. I've personally learnt a lot from your videos, it is very hard to get these cells here in Pakistan, but I still found a way to get them for my EBike as they are much safer than lithium ion. I'm running 24s1p. thank you so much for making these videos bro.
Hi Will - Nice video addressing this issue. I think some of the comments may be innocent in nature and wanting to learn, while others are made out of ignorance or even lazyness. There are so many different chemistries on the market now, it is naive to assume they all work the same. A common message I often give to my younger, less experienced engineers is READ THE DATASHEET. It is remarkable how many people disregard this basic information. Personally I really enjoy watching your videos and find them instructive. I particularly love it when you do a tear down and debunk the claims of some of these "fly by night" vendors. People seem to forget that if something is too good to be true, it usually is. Praise the good guys and call out the rats. Keep doing what your doing man, you are helping us all.
"Because we're not getting rated capacity guys what are you thinking" pulled a chuckle outa me for sure. Way to make an extremely mature and calm "stfu" video for the doubters. Keep showing us the way good sir
Ignorance in a comment section? NEVER!!! 😂😆🤣
AnotherDayInParadise well these guys thought they were smart was the real issue 🤣 if I asked a stupid question which I have Will was so nice with his answers. I love that he can get Savage if needed 🤣🤣🤣
Ignorance is a lack of specific knowledge and is certainly appropriate in this case. Be sure you understand the meaning of the word, not the common misconception of ignorance implying low intelligence.
The more someone knows, the more they realize how little they actually know. Ignorance is a constant, ever changing, state of being.
You tell em Will, I hate when people jump on and start babbling bullshit, and in the first few words you know that they have there battery chemistriestrys mixed up, or just have no idea what they are talking about at all!!!
Dunning-Kruger in full effect lol.
I think this is a learning channel, not a trolling channel. Because of all the knowledge from this channel, I just completed my first solar setup in my van. Thanks Will.
LOL. I’ve been using LiFePo batteries for 10+ years. You got it all solid.
Keep cruising
😎👍
Aquarion H2O Yes, I wonder how anyone can claim 30 years of LiFePo experience!
David Davis The were the originating Chemist that pioneered the battery chemistry.😂👍🥴
Are the 10 year old lifpo4 cells still going? Thanks
jay kup Yes.😎👍. “A123” cells. No clue how many cycles are on them though.
That's good to hear.. I got two different set 1 is 4 years old one is going on a year.
When watching (and enjoying) your educational videos I may only understand about 10% of what you are saying, but I have complete confidence in you. Clearly you know what you are talking about and, whenever I need to learn about solar charging and batteries, I turn to you first. Thank you, Will. Keep ‘em coming!
"Watch my beginner videos!" HAHAHA!!! Too good
Hello Will. Finally! A fellow with real knowledge and expertise about electrical power who is evaluating electrical devices. You are a breath of fresh air. All my life (now a septuagenarian) I've struggled to understand the basics. Michael Faraday I am not. So now my journey begins. I'll watch you videos and look into your book. Maybe I can gain enough knowledge to be proud of myself by overcoming my ignorance. I guess I should begin with your oldest video.
Hi, your are spot on with what you are saying in this video and the processes you use to test these batteries. Some people confuse lithium with lead acid and even think all lithium chemistries are the same. Ps, I am an electronic engineering that designs commercially available chargers for all different battery chemistries, thus if I was wrong about this stuff I would be in big trouble. Keep up the good work 👍
Thank you Mr. Prowse. Your videos are like condensed versions of whole books and courses in a very well prepared, produced and delivered manner. You are the go-to guy for anything solar related and batteries.
It's like college level classes I can in the comfort of my home on my computer. You're a great guy for educating us and putting up with the ignorant haters that seem to troll on UA-cam.
This is one of my favorite videos, where everyone thinks they are an expert on social media and always have to be snarky about it, I love that you corrected them with the "facts" and "science", in such "anti-science", "anti-factual" or "alternate facts" times LOL thanks Will for your videos :)
I really like how your rebuttals are data driven and explained so well. No arrogance or anger on your part. Thank you for your videos. You have no idea how much they have helped me!!
Guy who says the high voltage cut-off per cell should be 4.2v does not know the difference between an NMC lithium cell and LFP cell....
Or between LiFePO4 and Li-Ion.
@@fg_354 Op was refering to what you just said. NMC for high drain li-ion, or LFP for LifePO4 batteries.Your comment added nothing :/
AKA ....
@@rilufuzz OK, I didn't know that. Sorry. I just call it Li-Ion. Like when I disassembled a laptop battery, those 18650 cells had Li-Ion on them so that's why I call them that.
throw LTO at them and watch them freak the fuck out. lmao. so much ignorance about lithium chemistries.
Will, you're proving that the saying, "a little knowledge is a dangerous thing" is alive and well. Your annoyance with the instant experts shines through in this video - good on you for responding quickly and effectively. Your videos are the best.
I love how calm he is talking down to people hahaha. Miss his voice and the long-ass streams he used to make, glad he is doing fine. Really smart guy and everyone should take his advice when it comes to lithium batteries.
Thank you for your patience, and thank you for sharing. I learn a lot from you and it comes across in your enthusiasm while you teach us. Thank you for all you do.
Thank you for all the great information you've given us. Keep up the well researched and accurate reviews !!!
Oh man I find it so wrong that you had to waste time and effort to make a video like this. But good on you for doing it anyway. You are the reason I had the confidence to order my 12V DIY LiFePO4 battery kid as well. It arrived today (super excited) and tomorrow being a public holiday here in South Africa I have all day to start building and testing my new kit. Thanks so much for the information you share, Without the work you do I would not have had the confidence to invest in this kind of battery as well. So my message to you is please keep up the great work you do there are many many of us out there that highly appreciate this.
consider doing these more often. I love reading the comment section and sometimes take my info from there because they speak with such 'authority', like they're in the know.
Yeah, when you are learning you don't know what's wrong, and usually you go to the comments to try and learn more. Fortunately will DOES know what he's talking about, but it's unfortunate for people that don't know him and read wildly wrong comments like these. One thing I've learned over the years is that some people just know enough to get themselves into trouble... And they tend to be vocal trying to show off. Running around telling people to charge to wildly incorrect voltages, or bringing up irrelevant effects that can cause you to waste money on unnecessary batteries isn't something a new person can recognize.
Mahalo, I'm learning and appreciate your straight forward testing with pro and con. Totally trust your opinion. A few years ago, with wrong advice from a local solar dealer on setting up a small solar system, caused a fire in my bus. So now I do my research, double check, and remain cautious on any product on the market. Again appreciate your honesty, and knowledge on these elements and products via your testing.
Never argue with Will. His knowledge is really good.
He is trying to be a good teacher, which is what I absolutely love about his videos.
don't worry about it champ, your videos are my primary resource when I need to know something about LiFePO4, BMS, Inverters or charge controllers. I think what you're seeing is a manifestation of the Dunning-Kruger effect
I wouldn't ever question you. I'm not that smart, but I'm smart enough to know you are.
Will, half of northern ca without power this is a great time to put your videos on Facebook advertising for these counties without power. Hundreds of thousands of people don’t have power for the next few days. I already put your video on my Facebook the one that is DIY solar system. God Bless
Break-in a battery? It's not an engine bro LOL
Their showing their age. This is not NIMH technology.
shows how there is still immense ignorance about lithium batteries, people still treat them like lead acid and nicd.
Aastan Hi, Shall I feel offended? I’m from the NIckel Cadmium age.... (ROFL)
And I love the school lessons from Will!
I follow his video since a long time and really learned so much that I build my own Energy Storage System out of a salvaged Volkswagen Hybrid Batterie.
Will, go on as you are. You do great!
Regards from Germany
@@Aastan I was thinking that myself! When I ran rc cars and I bought new sub c cells to solder together you had to charge/discharge them a few times before they would put out the rated mah capacity.
@@MrRossi1805 Not in the least. I am from that era too. NIMH in my Rearwind Speedster.
If only there was a UA-camr that’s spent a large amount of time learning and testing and dedicated their channel to solar, batteries, and components that could make videos you could watch to teach all these concepts and show test results. They could provide it for free in an easy to digest way. That way people could post how he’s wrong in every way possible.
Great roasting them. Some people are just ignorant but those that are arrogant deserve the roasting. Thanks for sharing all your hard work, it’s a benefit to many people.
Soooo frustrating when comments like those are made! I deal with messages and comments like that daily and I sympathize. Thanks for this video! Hopefully it inspires some to do more research before posting. Yea, 0.2C discharge rate for capacity testing is the standard for Li-ion chemistries and it’s not hard to learn that with a bit of reading.
My favorite battery guys' views align, once again!
Way to call out these people. It's amazing that they do not know the chemistry and/or discharge. Will I have to give you props on your educational info. Keep up the good work young man. Your work with this chemistry is unprecedented.
Thanks for being one of the few that maintains their integrity, Will!
I love these videos. It's a nice way to keep people from falling for disinformation while giving the rest of us a refresher and deeper understanding of everything you've been studying and learning. Keep up the great work!
You sir have the patience of a god.🤣
Almost. A God wouldn't have felt a need to call them out by name and would have simply addressed the misinformation. He handled it with a degree of patience and politeness, but there's still room for improvement.
Hey Will, just for your readers (not that they will really care what I have to say) I sent your links to our CTO (solar power company) and he gives you five stars, "really smart". I have worked with this CTO for over 10 years and trust his input and evaluation. You are golden.
Good one Will. Throw it "nicely" straight back at em.
Hi Will
Thx for the vid. Being a Complete beginner with solar is confusing with all the misdirection on the subject. Having someone thoroughly knowlegable doing beginner videos is great. A separate playlist for beginners is top shelf.
This was a good video, put them on blast LOL
Stand fast my friend against the trolls. Your chanel has tought me so much as to disregard the trolls. I have a physics background and everything you have said, done and tested it makes sense. No need to defend. You have the high ground Matey. Stand high and proud.
Lol. That was entertaining Wil! Keep making great instructional video’s for our enjoyment.
I been watching for over a year now, and you REALLY know your "stuff". I got interested in this topic because of one of your videos.
Continued joy and success.
@wrpiii, now that you've got a year under your belt, navigate to the Endless Sphere forums. This is where actual engineers go to work on their off-duty projects. BMS design, testing using actual standardized protocols, and a couple of decades of real-world performance testing. Spending a year there will show you just how 'amateur hour' most lithium info on youtube really is.
Will, don't lett these idiots affect you. You have great knowledge of thees battery's and systems. keep up the good work with educating us. Tb
This dude is a BOSS. You don't question Will, Will questions you! I don't buy solar or lithium equipment unless specifically approved by Will Prowse.
LOL! Oh Will, this is why I love you and your channel! A young man with integrity and a genius mind who applies himself consistently to the facts and isn't afraid to call out arrogant know-nothings, by name. And we can see by the thumbs-down that you hit the mark squarely, ha! You're the only one I trust to learn about all this stuff. As always, a true and excellent teacher. Well done!!!
*Searches comments to see if the accusers have made any new comments* ...nope!
You're the most knowledgeable expert on lithium cells, solar and inverters I know of even 2 years later.
lol, "watch the beginner videos" - Burn!
Haters will be haters. Ignorant haters are even worse. I doubt VERY few of your viewers have the knowledge on this chemistry as you do. You can try to teach them and SOME will learn but most haters will always be haters. I appreciate your knowledge and presentation. Keep up the good work!
Some people think speaker wires need to be "broken in", there's no hope I'm afraid.
I thought they needed to be precharged! LOL!
They need five turns per watt around a Himalayan salt crystal. ;-)
So I bought a Lithium 200 amp hour battery off of Amazon for $1,300 to use with my two 200 watt panels. With 400 watts of solar and 200 amp hours of battery my van will have plenty of power 😃 . Thanks Will for the awesome information on how to set this up! My costs were less than $2k.
I was told you need to top up the electrolyte with some distilled water. :)
By injecting it with a metal syringe :)
Incorrect these ones need soaking in water to replenish the boiled off juice from running them at low discharge, its best in salt water as this really excites the molecules into a chemical reaction.. Warning the battery may get very cold during this period so give it some love.
@@DUB-sential I do the same thing but with pulp free orange juice.
@@pstearns6164 yeah mine likes the bits left in sadly
Dude, Love your videos. Respect you as a knowledgeable solar/battery expert. Keep on making videos and educating and enlightening us.
These comments just go to prove that you can't fix stupid.
Yup!
Amen brother.
"You can't fix stupid", is a Ron White quote, not Stephen Wright.
I read it fast and saw Steve wight's name and thought someone was crediting the quote to Stephen Wright.
This cracks me up! These people need to watch and learn! You obviously know what you’re doing. I’ve watched a bunch of your videos and have learned a lot. One thing I haven’t seen you talk about is changing from lead acid to lithium in an RV and any precautions one should take and how this change will affect my ECM. My son and I are getting ready to get rid of my 4 house batteries and put in 2 new Battleborn batteries. Any advice would be appreciated or if you have covered this in a video please guide me to it, Thanks Will! I love your videos!
You may need to leave specific links to your 'training wheels' videos each time.
You can lead a student to text books but you can't make them think...
Nice Will, this is why I watch your work I trust your knowledge I'm a beginner and could tell the people in the comments were obviously talking about lead acid or didn't know what they were talking about
I personally appreciate the amount of effort you go to to educate your subscribers on how to build, buy, and maintain a system safely for years to come. Thanks Will.
You tell them my friend.
Touché Will! Henderson, NV is lucky to have you. Another smart move with climate and no state income tax. Here in Utah we could learn some things. Well I’ve got your configuration on my kitchen table and I’m buttoning up as we speak. My 400 watt panels are mounted not plugged in on my 1 1/2 inch pvc pipes ( portable stand to be used at the cabin or RV) we have 4 feet of snow on the ski resort we live on and a scheduled plan to BLM near Vegas in 30 days. You rock and my wife says your so dang cute too.
Class dismissed!
To folks who want to undertake lithium battery projects your channel has been very informative. Please do not get too concerned about bonehead comments. I would think that most people who follow your channel pay little or no attention to them. Keep up the good work!
Will, where are you!!! Its been a month and i don't mean to be a slave driver but i miss the content from this channel
Haters are always going to hate. Don't let it stand in your way. Your knowledge and integrity is genuine.
You've taught me everything I know about lifepo4. Keep up the great work mate 👍
Lol.... all the Google University graduates came out on that video.
I like this guy more and more! Way to explain without being negative, that's more than most can accomplish. My old brain has learned a lot from you, thank you.
