Right now I'd be happy with those cheap batteries . Waiting on disability can't work and my 200ah won't run everything in my camper so it's hurry up and wait 😂
I'm so happy the grade B cells are getting some love! The battery is garbage but when $50 matters, it's at least a good quality build. Thanks for the teardown.
... the capacity is only gonna go down from there... 81%... in my books they are pretty much done...they are a bit cheaper now... go for the Pro series with Grade A cells.
I think this is great! Many people who mostly camp with electric hookup don’t need 100ah but offering them a LFP option which has less risk of going bad if it gets to 0% is an amazing option for those people. Furthermore, repurposing batteries is great for the environment. They give additional 3-5 years (maybe more) of life rather then going to a dumpster. The only think they need to do is to clarify these are repurposed cells - otherwise, it’s a great option for many people at a great price.
I completely agree with your comment! Offering a LFP option for those who mostly camp with electric hookup is a fantastic idea. It not only provides a safer option but also helps in repurposing batteries, which is great for the environment. And regarding the Segway Portable PowerStation Cube Series, it seems like a reliable and powerful backup power solution with its massive capacity, fast recharging, and comprehensive protections. Definitely worth considering for outdoor enthusiasts and RV lovers.
Will You will love this Dear Gary, Thanks for your reply. The battery case is the public moulds on the market. So there is some extra open space unused space inside the battery. If we use the dedicated moulds for this battery, which means we need to open a new mold. The cost will be very high.
Having fun watching your videos and hopefully learning in the same way people learn a second language through immersion. Full time RV senior here... with (2) 200 AH MGA batteries hoping to upgrade to lifepo at some point soon... and studying what's involved on youtube university. Thanks for the fun lessons!
That would be something for a UPS system. Just lot capacity, not many cycles, size and vibration quality doesn't matter. Build to leads and hookup any regular old UPS and have massive more reserve for the price of a lead battery. Most UPS do like 2-3 cycles a year.
@@aerobiotic They do make LFP UPS systems but they are much, much more expensive. Would be neat to grab one of those controllers somehow? I'm loving the idea of a LFP UPS on the cheap though! Would be awesome for my work server cabinet as the two UPS in there can't last more than 5-10 minutes.
I have done Lifepo4 conversion in my apc br1000g in and it is phenomenal. I used discounted old cells 16 of them cost me 50$ they were cheap cus they were manufactured in 2019 and i bought them in 2022. , The tested capacity of the whole pack was 12amp hr which is correct rated capacity for those 32700 6000mah cells. I used 300w resistive load on my ups and it ran the load for 45mins that is similar runtime to having 27ah lead acid 24v batteries on my ups. So which would total well over 3 times the money i spend on these Lifepo4 cells. My ups charges them to 29v and then goes into absorption at 27v. I did not use a bms , i am only using a cell balancer cus the ups is handling the charge and discharge voltage. And i do not want the bms to suddenly disconnect the pack from the ups if that happens the ups will not power back on automatically when the mains is restored and the ups terminates at 21v anyways so there is no need for a bms and waste energy on heating those mosfets just use an active Lifepo4 8s balancer. There is no issues with charge current, my ups charges the 9ah lead acid pack at exactly 1.25amps or the 27ah lead acid pack at 3.75amps , i have set mine to do it at 3.75amps cus my battery pack can easily handle 6amps of charge current. The run time is phenomenal i can game on my pc for 40mins without any worries or do my work for well over an hour as my pc consume just about 150w at idle. There is one issue that u have to keep in mind. If your ups uses low frequency inverter then u should keep in mind that the models are designed to save money and they save money on the transformer size , u can not run at even 50% load for longer than rated run time , i have blown the transformers internal thermal overload fuse on my dads ups which has the cheaper style low frequency inverter using a large transformer even though that model is rated for 660w the transformer in it is half the size of the transformer apc was using in their 300w ups from 2004. I was running that ups to see how hot it gets and at 600w load the transformer got to 80c before blowing the fuse , it ran for 4mins on that load which is 4 times longer than what apc claims as run time on similar load with original apc batteries 😂. So in my opinion avoid ups with low frequency inverter only get the ones that use smps style inverter those are much more efficient and can run longer at near full load condition without blowing up. Or if u have no other option then keep the battery capacity low. If the original ups came with 7ah 12v battery using 6ah Lifepo4 is like having 14ah lead acid. So do not run for long time with more than 50% load in that case , also keep in mind to purchase cells that can handle the maximum power draw. A 600w ups can pull near 30amps on 24v battery and so u should keep the Lifepo4 capacity at half of that. So that the maximum load on the cells can not exceed 3c discharge.
@@aerobiotic most UPS with a AGM battery should be very close to a LFP battery cycle. They might not charge very fast or even all the way full. My APC units float at around 13.6V depending on the model. Further you should not try that with UPS at full capacity. They don't have the thermal. I got for instance 650w UPS and I'm using it for router and other things - which draws less then 70w. Never getting warm.
@@aerobiotic The BMS is your charge controller. You can just input any constant voltage. A dedicated Lithium charger is not really required, but I would use one because the BMS used in these cheap batteries are typically Chinese junk that can't be relied on in an enclosed space like your RV or car.
Thanks for being cool and so knowledgeable on this subject matter, Will. You are an invaluable YT resource, especially with the growing threat of electric grid brown/black-outs in industrialized countries! I’m working up a small-ish-but-expandable 48V household back-up system for our Utah-based place mostly because of your generous training. Question: In your opinion, are the 24V BattleBorn or 24V SOK battery systems still two of the better valued battery solutions for a small-to-medium sized 48V system? Anyone else, please chime in. Thanks.
In terms of better-valued battery solutions, I believe he mentioned the EG4-LifePower4 Lithium Battery from signature solar being a good option, where they have them in 48v battery systems. BattleBorn and SOK are in the same tier, in my opinion, however, they cost a lot more compared to EG4's.
It seems that they were trying to be honest with stating 950 Amp hours. But you're completely right about the cycling , how does one really know how long it with last . What a completely awkward case for the battery , where do you place it. It ridiculous how large it is. It's like a 48v size for a rig or dump truck. Thanks for sharing this with us all and we'll see you soon my friend . Cheers
Great Channel and I love how you thoroughly give your input and specs, I especially love the ecoplus Delux setup video. You are the go to guy when it comes to solar and battery generators
Thank you for all of your work on the channel Will. I enjoying learning what you share and your infectious enthusiasm. With the degraded cells, the large case could hide any swelling that the batteries experience in the future. Or if some of the cells were swollen to start with.
I can see a place for this in older used RV's that have limited service life left, consider that a typical modern lower end travel trailer only have about a 15 year service life before they tend to end up in a scrap yard, and I can certainly see a place for these replacing the first or second set of lead acid batteries at the 5-10 year mark in the service life.
Just bought one and put in my hydro green house to run my pump and aeration. the company has already called to see if I was happy. I will keep you posted.
I think they made it that size because it is a direct replacement for an RV deep cycle battery, and they want it to fit securely in the same space without having to modify the battery box and hold downs.
That's crap, I'm sorry. I like that they're honest with the rating calling it a 95Ah, but putting used (or otherwise reject poor-performing) cells in there and marketing it as "new" is... fraud? No thanks. The big problem with these kinds of things is the large amount of people that just search for a product on Amazon and order it not having any clue they're buying. Maybe they need to market it as "refurbished" with 95/120Ah life remaining.
I have no pity for people who just do a quick search then buy, and even less for those who believe the 'stars' and reviews on Amazon actually have meaning. Or on any of the other usual online mega-stores. Which is why what you and Will do matters so much- you save us from that avoidable grief with your knowledge and testing. BIG thanks!
@@P_RO_ I agree with you, and I disagree with Will on this one. I actually have one and I bought 2 more. Using for low amperage lighting in my shop and shipping container, and running small hand tools off of a 1000w modified sine inverter (angle grinder, sawzall, pole saw, all work fine).
As a battery manufacturer in China, Thanks for your sharing. I always learn much from your video, then I will know What aspects of the product do the buyer will care about, how should I introduce our batteries, and what are our advantages? We should ask you to endorse the product. The internal structure of each of our battery is amazing, and the cells are all brand new. Many trading companies approach us to cooperate, but we prefer to find some end users who can recognize our products.
If you use a trolling motor 100 times a year this would work . Light weight and no worries about taking it down to 10%. 1000 cycles will give you 10 years, and, by then battery tech will be so much better. Sodium or sulfur.
Thanks for the info. You do very good reviews. I drive a semi truck. With the diesel been very expensive now I’m installing a one ton mini split ac on my truck with a gas generator. I want to get a good lithium battery’s. I drive in very hot and cold climate another thing is vibration. This info is going help a lot. 👍👍👍👍👍
You can still get Grade A 105 ah prismatic for 250 or less, for 4s the mazzive case without the capacity to match would have me always asking "where's the beef?" And only 50 amps! I'm glad you cracked it open thanks Will
Can you get when they were manufactured from reading the barcode? They have to be a couple of years old If they are cycled ones. Nice that they were well matched, but as you say; Better to add some extra dollars to get more capacity and better bms. Great video!
As far a bad internal mounting and securing the cells in place, I think that the lid (that you removed) would hold the cells down inside the case. Foam was a deep-ish pocket, so it should stay put. Those top foam pads on the lid were touching the tops of the cells ... I recall the tested capacity sticker was stuck to them. Anyway, looking forward to the capacity test.
There’s a reason they put a 50 amp BMS on that battery, and it probably has nothing to do with cost. The battery likely can’t support 100 amp loads given its age and cycle count.
Hi DIY. I have bee watching your channel for years. I damaged my 200 amp 24 volt Chin batter by not being careful as I dropped socket drive and it hit the terminals... WOW ARC FLASH! Glad I had safety glasses on thanks to your safety tip. I would like to see you do Chin BMS replacement operation.
My guess would be this battery is going to be marketed in Africa and Asia for rural people and for back-up power and lighting systems in the cities. It's rather brilliant, IMHO. The bigger ABS plastic box and foam chunks don't add much cost for the manufacturer but make it close to the same size as a typical "4D" lead acid battery with around a 100Ah capacity rating, BUT much lighter and WAY better because of the LiFePO4 advantages of cycle life and tolerances of deep discharge, etc. At that price, they will be price competitive with cheap Chinese AGM, and even the grade B or used LiFePO4 cells will perform better and last longer than a lead-acid battery that sits at 30 to 40 degC most days. They will also be easier to ship because they all have built-in protective packaging so they don't need extra foam or wooden crates to ship individually. Thanks for all your great videos!
I bought a set of 80% Dyson 2170 cells for my cheap cordless, great performance and plenty capacity till now. I say this is not bad for those who can't build their own batteries. I just wonder how these cells were used, it is like they cycle these several times a day.
Thank you will oh my gosh I ordered four of these 200 amp hours I had no idea these were used cells I called Amazon and returned all four of them one week after they were delivered it's a good thing I saw your video the company reached out to me and asked me how come I don't want these four 200 amp hour batteries of theirs they asked me if I saw a video on UA-cam is that why I want to return them when you buy the batteries on Amazon they don't tell you if they're new or used or if the cells are used it's a good thing I would have been stuck with $2,800 worth of batteries do your research everyone thank you again will
Thank you that was short and sweet and you're recommendation of not buying it is probably a good one. Unless you're in the market for a lead acid battery and you have unlimited room and you're cheap. But I don't think those planets are going to align. Thank you for another cool video.
For that money I might just buy one and see how long it lasts. Use it to light a barn. I've often wondered what the performance would be like after many years of use. This might be a shortcut way to find out.
Just bought it to replace the 2 x 75ah deep cycle batteries in my class C that recently went dead. The ridiculous case dimension is actually an exact fit for the door-step battery tray. I think the 50a bms might "match" lead-acid charging current and avoid tripping any 12v breakers or burning alternator, so as a cheap guy who don't want to invest in another dc-dc charger, this seems what I need.
I did an experiment. The battery when completely empty (discharged to 10.1v) would briefly accept about 1100w. But immediately after that the charging current was regulated to 370w and gradually dropped as the battery approached 13.6v (the preset voltage of my RV converter, non-adjustable). So it worked, sorta --- just never deplete the battery to 10.1v and it should be good (the 1kw current did trip my 12v breaker). And remember your lead-acid charger will not charge this thing full.
@@larryperry2094 Well I'm not relying on its capacity since I have separate powerstations to provide 110v. However it's powering my 30lb trolling motor for 2+ hours no problem.
This is good for low cycle application but i would get rid of that bms if i am using this in a ups and i will add an active cell balancer just to squeeze out some of the extra capacity
It's good to re-use old cells - if there's a market for it. Better than shredding and recycling. Any extra life that can be squeezed from an old battery is a good thing imo.
It does appear to be marketed towards Rv's. Many RV operators are on a tight budget, the battery case is actually perfect because many are already set up to hold that battery size so its just a matter of sliding it in and replacing the old. So, compared to a traditional lead acid deep cycle battery many older RV's have this very well may be a good battery. If it holds up which as you say is an unknown. With my old setup all I ran was lights, Tv and water pump the 50 amp BMS is just fine.
I am looking for a cheap battery to run my garage exhaust fans, and something like this I could see working for many years. I have a couple older panels and a cheap controller I'm going to use, instead of buying some cheap lead, this could work. not sure I would run it with anything too important for the reasons you said, but hey, worth a try :)
I like your frank eval's. I look for the cheapest deals. For $50.00 more I get twice the use I will probably talk myself into the expense. Thanks for helping me make up my mind!
The other thing is... the batteries are connected LENGTHWISE... not widthwise, making the battery longer... should have been connected widthwise... for better space use.
I've been interested in this (price $270 free shipping) TimeUSB offering on Amazon for several months. I have a 25ft motorhome with one agm battery and 215-Watt solar panel which will be joined to another 200-watt panel soon. Will: "It may outlast a lead acid." I like that idea. Except for the extreme size, this, I think would be a good addition to have. I like the idea of the 50 amp BMS to not overload the alternator while charging. I read on Amazon that one customer received a bad battery and the company responded very well in replacing it in a timely matter. I'm waiting anxiously for the test results from Will.
BMS doesn’t regulate current limit, it will either burn up or disable charge, in both cases it’s not usable if your alternator can produce more than 50A
Hey sister, we need an Amazon review from a customer who received a bad battery and got it replaced very well in a timely manner, so a random person will refer to it in the comments section on Will Prouse's youtube channel.
I just bought 4 Lifepo4 138ah 12v batteries for a total of $200 with free shipping from China. I am not worried one bit. This will be my greatest purchase ever, and will talk about this deal for years.
Chins battery is $100 more or almost 50%. I bought one of these instead as it will be used infrequently in a trolling motor, Saved the money and have a better set,up than lead acid imho,
Hi Will, have you ever looked into Nickel Iron batteries? Iron Edison sells them in the US but you can get them directly from China. I know they have a lot of downsides (the easiest for me to understand being maintenance), but their longevity appeals to me. Would love to hear your thoughts!
The fact that all cells were matched and voltages were 2.95-2.97 wouldn't bother me much..!! These could be brand new B cells that just didn't pass capacity testing...!! Happens all the time..!!
I have been hoping that you would review this battery! I appreciate the video but would have liked to have seen a load test to see what the actual output was.
I am currently looking at a cheaper than normal lithium battery on Amazon, but after seeing this video I have lost all confidence in the market, so I think I will trade up to AGM. I wanted lithium phosphate, but there is no way I am going there now. thanks for sharing.
on the amazon site you see they also sell a 100 Ah battery for $70 more and it has a 5 yr warranty.. apparently the 95Ah has no warranty or 90 days.. also something funny when asked about if the cell are new or why they are using 80% capacity cells in the 95Ah batter they go around answering the question with stuff like.. "The Timeusb 95Ah battery that born for RV with UL/FCC/CE/ROHS certificated. and each battery cells from us are ensured with 100% strict inspection and they are qualified." what does "they are qualified" even mean.. LOL.. other words they have no clue are don't are wont say.. Still not a bad deal if you just need some cheap batteries for project but getting better cap for little more make better sense to many.. cheap is and always will be CHEAP.. Thanks Will... another great show for sure..
Battery longevity and variance of quality at manufacture is still such a mystery to us and probably even to manufacturers to an extent. They are learning, I guess. I salvaged some batteries from a well-used 20 year old laptop. Six lithium ion cylindricals 18650s and after 20 years and nearly as many that they have been zilched by my laptop. Five of the 6 are corroded and utterly unuseaable and one is now powering a converted 2 D cell flashlight and drawing nearly new capacity. Go figure.
If the case wasn't so large they would be perfect for the average RVer who is only going to cycle them a few dozen times a year at most and only running lights/water pump/propane fridge controller. That price is getting close to the cheap flooded batteries that most people run in RVs.
Looking at the Docan Power website their return policy whether their batteries are faulty upon testing or damaged in transit that the BUYER has to pay full return cost, which is very surprising. For me, despite them having EU stock being in the UK, that cost would be outrageous to return if there were any problems. Making buying from them impossible. Which is a shame as I really like your recommendations. The going rate in the UK for these cells (280ah 3.2v) is £180 each, where Docan Power is $149 (£126) each including delivery. Quite a difference. If you could recommend a UK seller at a more reasonable price I think we here in the UK would clear their shelves. Thanks for your content.
You mention low temp charging in every video and how you can destroy a battery by charging when it's freezing. So....can you do it? What happens and how does it die?
My guess for the origin of the apparently recycled CATL cells used in this battery is tow motors used in Chinese warehouses. It is pretty interesting that the battery assembler chose to use a battery management system rated at less than 1/2 (of the remaining) C of the cells.
I might not have a problem with this battery if the manufacturer disclosed the cells are recycled. A purchaser naively expecting new cells is probably only going to receive half the discharge cycles anticipated. Paying $50 to $100 US more and getting a new cells is a better deal compared to having to purchase two of these batteries to get the same service life.
Hi I got 2 200 ah for £269 each from litokola on Ali express and are working great so for the price even if they last 3 years I'm winning I've got a frezzer and fridge and cook on induction and air fryer kettle toaster all on inverter and I never go bellow 12.00amps sitting around 12.3 amps
Maybe for a cheap 12V system in an off-grid situation where it never freezes or for someone who needs a small solar system inside the van they put too much money into to travel trying to make UA-cam videos and ran low on money due to high fuel prices? You never know?
It would be great to see the difference in internal resistance. If they matched that too, then great. If they're way off, then this will become an eternal balancing nightmare.
My guess on the size of the case is either: (a) they got a great deal on that size case, (b) it's easier/cheaper for them in production to maintain all the same supply of parts to build their various capacity batteries. My only beef with these batteries is that they should disclose WHY these are "grade B" cells. Used or just poor post-production performance "rejects"? It can make a difference depending on the application someone wishes to use them for.
Hi will watched the vid. Great info have lifepo4 here in the Philippines for 120 dollars .After watching I decided to buy a more expensive one try to get awa from used cells no guarantee here. Ok thanks

Pray you get 1m subs
Right now I'd be happy with those cheap batteries . Waiting on disability can't work and my 200ah won't run everything in my camper so it's hurry up and wait 😂
Your information is priceless buddy.
This battery could be good for a driveway gate or something similar.
I'm so happy the grade B cells are getting some love! The battery is garbage but when $50 matters, it's at least a good quality build. Thanks for the teardown.
I'd be happier buying the grade B cells themselves without paying for their packaging overhead.
... the capacity is only gonna go down from there... 81%... in my books they are pretty much done...they are a bit cheaper now... go for the Pro series with Grade A cells.
I think this is great! Many people who mostly camp with electric hookup don’t need 100ah but offering them a LFP option which has less risk of going bad if it gets to 0% is an amazing option for those people. Furthermore, repurposing batteries is great for the environment. They give additional 3-5 years (maybe more) of life rather then going to a dumpster. The only think they need to do is to clarify these are repurposed cells - otherwise, it’s a great option for many people at a great price.
I completely agree with your comment! Offering a LFP option for those who mostly camp with electric hookup is a fantastic idea. It not only provides a safer option but also helps in repurposing batteries, which is great for the environment. And regarding the Segway Portable PowerStation Cube Series, it seems like a reliable and powerful backup power solution with its massive capacity, fast recharging, and comprehensive protections. Definitely worth considering for outdoor enthusiasts and RV lovers.
Obviously bigger is not better in this case.

Dear Gary,
Thanks for your reply.
The battery case is the public moulds on the market.
So there is some extra open space unused space inside the battery.
If we use the dedicated moulds for this battery, which means we need to open a new mold. The cost will be very high.
Having fun watching your videos and hopefully learning in the same way people learn a second language through immersion. Full time RV senior here... with (2) 200 AH MGA batteries hoping to upgrade to lifepo at some point soon... and studying what's involved on youtube university. Thanks for the fun lessons!
That would be something for a UPS system. Just lot capacity, not many cycles, size and vibration quality doesn't matter. Build to leads and hookup any regular old UPS and have massive more reserve for the price of a lead battery. Most UPS do like 2-3 cycles a year.
UPS charging controller is likely a lead acid profile. Would that still work?
@@aerobiotic They do make LFP UPS systems but they are much, much more expensive. Would be neat to grab one of those controllers somehow?
I'm loving the idea of a LFP UPS on the cheap though! Would be awesome for my work server cabinet as the two UPS in there can't last more than 5-10 minutes.
I have done Lifepo4 conversion in my apc br1000g in and it is phenomenal. I used discounted old cells 16 of them cost me 50$ they were cheap cus they were manufactured in 2019 and i bought them in 2022. , The tested capacity of the whole pack was 12amp hr which is correct rated capacity for those 32700 6000mah cells. I used 300w resistive load on my ups and it ran the load for 45mins that is similar runtime to having 27ah lead acid 24v batteries on my ups. So which would total well over 3 times the money i spend on these Lifepo4 cells. My ups charges them to 29v and then goes into absorption at 27v. I did not use a bms , i am only using a cell balancer cus the ups is handling the charge and discharge voltage. And i do not want the bms to suddenly disconnect the pack from the ups if that happens the ups will not power back on automatically when the mains is restored and the ups terminates at 21v anyways so there is no need for a bms and waste energy on heating those mosfets just use an active Lifepo4 8s balancer. There is no issues with charge current, my ups charges the 9ah lead acid pack at exactly 1.25amps or the 27ah lead acid pack at 3.75amps , i have set mine to do it at 3.75amps cus my battery pack can easily handle 6amps of charge current. The run time is phenomenal i can game on my pc for 40mins without any worries or do my work for well over an hour as my pc consume just about 150w at idle. There is one issue that u have to keep in mind. If your ups uses low frequency inverter then u should keep in mind that the models are designed to save money and they save money on the transformer size , u can not run at even 50% load for longer than rated run time , i have blown the transformers internal thermal overload fuse on my dads ups which has the cheaper style low frequency inverter using a large transformer even though that model is rated for 660w the transformer in it is half the size of the transformer apc was using in their 300w ups from 2004. I was running that ups to see how hot it gets and at 600w load the transformer got to 80c before blowing the fuse , it ran for 4mins on that load which is 4 times longer than what apc claims as run time on similar load with original apc batteries 😂. So in my opinion avoid ups with low frequency inverter only get the ones that use smps style inverter those are much more efficient and can run longer at near full load condition without blowing up. Or if u have no other option then keep the battery capacity low. If the original ups came with 7ah 12v battery using 6ah Lifepo4 is like having 14ah lead acid. So do not run for long time with more than 50% load in that case , also keep in mind to purchase cells that can handle the maximum power draw. A 600w ups can pull near 30amps on 24v battery and so u should keep the Lifepo4 capacity at half of that. So that the maximum load on the cells can not exceed 3c discharge.
@@aerobiotic most UPS with a AGM battery should be very close to a LFP battery cycle. They might not charge very fast or even all the way full. My APC units float at around 13.6V depending on the model. Further you should not try that with UPS at full capacity. They don't have the thermal. I got for instance 650w UPS and I'm using it for router and other things - which draws less then 70w. Never getting warm.
@@aerobiotic The BMS is your charge controller. You can just input any constant voltage. A dedicated Lithium charger is not really required, but I would use one because the BMS used in these cheap batteries are typically Chinese junk that can't be relied on in an enclosed space like your RV or car.
You Sir, are a beacon of light to the solar user masses!
Thanks for being cool and so knowledgeable on this subject matter, Will. You are an invaluable YT resource, especially with the growing threat of electric grid brown/black-outs in industrialized countries!
I’m working up a small-ish-but-expandable 48V household back-up system for our Utah-based place mostly because of your generous training. Question: In your opinion, are the 24V BattleBorn or 24V SOK battery systems still two of the better valued battery solutions for a small-to-medium sized 48V system?
Anyone else, please chime in. Thanks.
Yeah we have to go solar as the globalists aregoingto turn off all the power grids
In terms of better-valued battery solutions, I believe he mentioned the EG4-LifePower4 Lithium Battery from signature solar being a good option, where they have them in 48v battery systems. BattleBorn and SOK are in the same tier, in my opinion, however, they cost a lot more compared to EG4's.
It seems that they were trying to be honest with stating 950 Amp hours. But you're completely right about the cycling , how does one really know how long it with last . What a completely awkward case for the battery , where do you place it. It ridiculous how large it is. It's like a 48v size for a rig or dump truck. Thanks for sharing this with us all and we'll see you soon my friend . Cheers
Great Channel and I love how you thoroughly give your input and specs, I especially love the ecoplus Delux setup video. You are the go to guy when it comes to solar and battery generators
I saw those batteries the other day on Amazon and immediately looked to see if you had cracked one open. Thank you.
I love your Curiosity about what’s inside everything and then teaching us what’s garbage and what not.
I just purchased 2 bats from that company,5,year warranty,great cust support
I just purchased one. They seem to be giving me the runaround not sure if it’s a trustworthy company.
Thank you for all of your work on the channel Will. I enjoying learning what you share and your infectious enthusiasm.
With the degraded cells, the large case could hide any swelling that the batteries experience in the future. Or if some of the cells were swollen to start with.
Ohhh damn ! I didn't think of that 😲
I can see a place for this in older used RV's that have limited service life left, consider that a typical modern lower end travel trailer only have about a 15 year service life before they tend to end up in a scrap yard, and I can certainly see a place for these replacing the first or second set of lead acid batteries at the 5-10 year mark in the service life.
Just bought one and put in my hydro green house to run my pump and aeration. the company has already called to see if I was happy. I will keep you posted.
Any update?
I think they made it that size because it is a direct replacement for an RV deep cycle battery, and they want it to fit securely in the same space without having to modify the battery box and hold downs.
That makes sense.
I literally just ordered one of these last night. I'll be using it to run a 7gpm 12v pump that draws 25 amps.
dude haven't watched you for two years and then I get on here and "let's cut it open..." just pure love for ya man
That's crap, I'm sorry. I like that they're honest with the rating calling it a 95Ah, but putting used (or otherwise reject poor-performing) cells in there and marketing it as "new" is... fraud? No thanks. The big problem with these kinds of things is the large amount of people that just search for a product on Amazon and order it not having any clue they're buying. Maybe they need to market it as "refurbished" with 95/120Ah life remaining.
Very fair point about labeling.
I have no pity for people who just do a quick search then buy, and even less for those who believe the 'stars' and reviews on Amazon actually have meaning. Or on any of the other usual online mega-stores. Which is why what you and Will do matters so much- you save us from that avoidable grief with your knowledge and testing. BIG thanks!
@@P_RO_ I agree with you, and I disagree with Will on this one. I actually have one and I bought 2 more. Using for low amperage lighting in my shop and shipping container, and running small hand tools off of a 1000w modified sine inverter (angle grinder, sawzall, pole saw, all work fine).
As always buyer beware!
Knowledge is power!
As a battery manufacturer in China, Thanks for your sharing. I always learn much from your video, then I will know What aspects of the product do the buyer will care about, how should I introduce our batteries, and what are our advantages? We should ask you to endorse the product. The internal structure of each of our battery is amazing, and the cells are all brand new. Many trading companies approach us to cooperate, but we prefer to find some end users who can recognize our products.
If you use a trolling motor 100 times a year this would work . Light weight and no worries about taking it down to 10%. 1000 cycles will give you 10 years, and, by then battery tech will be so much better. Sodium or sulfur.
Thanks for the info. You do very good reviews. I drive a semi truck. With the diesel been very expensive now I’m installing a one ton mini split ac on my truck with a gas generator.
I want to get a good lithium battery’s.
I drive in very hot and cold climate another thing is vibration. This info is going help a lot. 👍👍👍👍👍
"Let's tear it open."
It's BOLTR time! Loved the teardown - thanks for posting. Thumbs up, and keep your stick on the ice.
You can still get Grade A 105 ah prismatic for 250 or less, for 4s the mazzive case without the capacity to match would have me always asking "where's the beef?" And only 50 amps! I'm glad you cracked it open thanks Will
That's standard RV battery size. It makes sense to use a standard case if it's optimized for RV use no modifications needed
Your work is like no other on the net! Thank you sir
Looks like these are made to be marketed to RV owners as drop-in replacements for units that use the physically larger batteries for house power.
Same dimensions as my ampere time 12V 200ah. Looks like the manufacturer just caught a deal on cases.
Probably to replace 2 6v lead acid batteries
Could also easily be the case here. I just know that most common folks don't look at specs but physical size when they buy things like batteries.
Can you get when they were manufactured from reading the barcode? They have to be a couple of years old If they are cycled ones. Nice that they were well matched, but as you say; Better to add some extra dollars to get more capacity and better bms.
Great video!
As far a bad internal mounting and securing the cells in place, I think that the lid (that you removed) would hold the cells down inside the case. Foam was a deep-ish pocket, so it should stay put. Those top foam pads on the lid were touching the tops of the cells ... I recall the tested capacity sticker was stuck to them. Anyway, looking forward to the capacity test.
There’s a reason they put a 50 amp BMS on that battery, and it probably has nothing to do with cost. The battery likely can’t support 100 amp loads given its age and cycle count.
It always amazes me how far they will to flog these, love your exposes’s. great work keep it up
Thank you for doing this. I was thinking about getting those, but since I'm new to this I didn't know why they were so cheap.
Hi DIY. I have bee watching your channel for years. I damaged my 200 amp 24 volt Chin batter by not being careful as I dropped socket drive and it hit the terminals... WOW ARC FLASH! Glad I had safety glasses on thanks to your safety tip. I would like to see you do Chin BMS replacement operation.
It may not be dead...just disabled by BMS, but can be turned back on by a certain charge or process.
@@mrmotofy Hi MrMotofy. I'm a novice to say the least. What do you mean certain charge or process?
@@mrmotofy what should I do?
If you disconnect and reconnect it should turn back on
Your cheap battery teardowns are my favorite!
My guess would be this battery is going to be marketed in Africa and Asia for rural people and for back-up power and lighting systems in the cities. It's rather brilliant, IMHO. The bigger ABS plastic box and foam chunks don't add much cost for the manufacturer but make it close to the same size as a typical "4D" lead acid battery with around a 100Ah capacity rating, BUT much lighter and WAY better because of the LiFePO4 advantages of cycle life and tolerances of deep discharge, etc. At that price, they will be price competitive with cheap Chinese AGM, and even the grade B or used LiFePO4 cells will perform better and last longer than a lead-acid battery that sits at 30 to 40 degC most days. They will also be easier to ship because they all have built-in protective packaging so they don't need extra foam or wooden crates to ship individually.
Thanks for all your great videos!
I bought a set of 80% Dyson 2170 cells for my cheap cordless, great performance and plenty capacity till now. I say this is not bad for those who can't build their own batteries. I just wonder how these cells were used, it is like they cycle these several times a day.
Thank you will oh my gosh I ordered four of these 200 amp hours I had no idea these were used cells I called Amazon and returned all four of them one week after they were delivered it's a good thing I saw your video the company reached out to me and asked me how come I don't want these four 200 amp hour batteries of theirs they asked me if I saw a video on UA-cam is that why I want to return them when you buy the batteries on Amazon they don't tell you if they're new or used or if the cells are used it's a good thing I would have been stuck with $2,800 worth of batteries do your research everyone thank you again will
Thank you that was short and sweet and you're recommendation of not buying it is probably a good one. Unless you're in the market for a lead acid battery and you have unlimited room and you're cheap. But I don't think those planets are going to align. Thank you for another cool video.
For that money I might just buy one and see how long it lasts. Use it to light a barn. I've often wondered what the performance would be like after many years of use. This might be a shortcut way to find out.
this is good choose if you use it at enviroment where there will be not so many cycles. Example summer cabin where you visit several times at summer.
Just bought it to replace the 2 x 75ah deep cycle batteries in my class C that recently went dead. The ridiculous case dimension is actually an exact fit for the door-step battery tray. I think the 50a bms might "match" lead-acid charging current and avoid tripping any 12v breakers or burning alternator, so as a cheap guy who don't want to invest in another dc-dc charger, this seems what I need.
I'm thinking about the same reasons that you are.
BMS doesn’t regulate current limit, it will either burn up or disable charging if your alternator can make more than 50A
I did an experiment. The battery when completely empty (discharged to 10.1v) would briefly accept about 1100w. But immediately after that the charging current was regulated to 370w and gradually dropped as the battery approached 13.6v (the preset voltage of my RV converter, non-adjustable). So it worked, sorta --- just never deplete the battery to 10.1v and it should be good (the 1kw current did trip my 12v breaker). And remember your lead-acid charger will not charge this thing full.
Sounds like perfect replacement. Are they still working properly? Capacity holding up?
@@larryperry2094 Well I'm not relying on its capacity since I have separate powerstations to provide 110v. However it's powering my 30lb trolling motor for 2+ hours no problem.
Recycle is good with the proper info....you r both right
Yeah as a supplier I love your video too.
You teach me so much and I‘d love to be your fans！
For the beginner not looking to really do any kind of high capacity or long term used, these actually look pretty decent to play around with
Thanks for the great help. Here in South Africa we are only exposed to cheap Chinese sweatshop crap. No battle born or similar quality
This is good for low cycle application but i would get rid of that bms if i am using this in a ups and i will add an active cell balancer just to squeeze out some of the extra capacity
Love your channel and I'm learning a lot. Still need to learn some fundamentals before I can really understand. Keep it up!
It's good to re-use old cells - if there's a market for it. Better than shredding and recycling. Any extra life that can be squeezed from an old battery is a good thing imo.
It's good to know what is really lurking in these cases so we can actually get a good deal appreciate the time you put in to share this stuff with us
It does appear to be marketed towards Rv's. Many RV operators are on a tight budget, the battery case is actually perfect because many are already set up to hold that battery size so its just a matter of sliding it in and replacing the old. So, compared to a traditional lead acid deep cycle battery many older RV's have this very well may be a good battery. If it holds up which as you say is an unknown. With my old setup all I ran was lights, Tv and water pump the 50 amp BMS is just fine.
They also make a 100ah battery with a 100a BMS for $299. Will you please review that one? I'm much more interested in that one.
I bought 3 so I'd be interested in that video as well
Have you seen the 100AH version? 100AH BMS, grade A batteries and not as big. I bought one for $259, and it's been awesome. Maybe review one next?
I am looking for a cheap battery to run my garage exhaust fans, and something like this I could see working for many years. I have a couple older panels and a cheap controller I'm going to use, instead of buying some cheap lead, this could work. not sure I would run it with anything too important for the reasons you said, but hey, worth a try :)
I like your frank eval's. I look for the cheapest deals. For $50.00 more I get twice the use I will probably talk myself into the expense. Thanks for helping me make up my mind!
Really like your analysis and explanations. Helps even beginners understand why this battery is such a bad idea!
Thanks a bunch!
The other thing is... the batteries are connected LENGTHWISE... not widthwise, making the battery longer... should have been connected widthwise... for better space use.
i bought two of these to run at 24v about two years ago and they have been running well. they are not under $200 which is crazy.
I really enjoy your videos. You are very knowledgeable and funny.
Since it's $130 cheaper than the cheap Amperetime battery, I'd use it for an emergency backup supply. You could get 300AH for less than $900.
I've been interested in this (price $270 free shipping) TimeUSB offering on Amazon for several months. I have a 25ft motorhome with one agm battery and 215-Watt solar panel which will be joined to another 200-watt panel soon. Will: "It may outlast a lead acid." I like that idea. Except for the extreme size, this, I think would be a good addition to have. I like the idea of the 50 amp BMS to not overload the alternator while charging. I read on Amazon that one customer received a bad battery and the company responded very well in replacing it in a timely matter. I'm waiting anxiously for the test results from Will.
BMS doesn’t regulate current limit, it will either burn up or disable charge, in both cases it’s not usable if your alternator can produce more than 50A
Hey sister, we need an Amazon review from a customer who received a bad battery and got it replaced very well in a timely manner, so a random person will refer to it in the comments section on Will Prouse's youtube channel.
@@CleanPowerAuto From what I've read on several reliable sites, the BMS does indeed regulate incoming and outgoing current.
Have you done a review on the
Fiunie 12v 100ah lithium battery ..
For $179. With low temp...
Just my opinion..
You do the best most complete reviews
I just got one of those and tested it at 106Ah under 60A load (it can handle full 100A). It seems to be decent quality but I haven't taken it apart.
I just bought 4 Lifepo4 138ah 12v batteries for a total of $200 with free shipping from China. I am not worried one bit. This will be my greatest purchase ever, and will talk about this deal for years.
Chins battery is $100 more or almost 50%. I bought one of these instead as it will be used infrequently in a trolling motor, Saved the money and have a better set,up than lead acid imho,
Even a grade B battery like this still much much better than new Lead Acid battery with its many potential problems.
Hi Will, have you ever looked into Nickel Iron batteries? Iron Edison sells them in the US but you can get them directly from China. I know they have a lot of downsides (the easiest for me to understand being maintenance), but their longevity appeals to me. Would love to hear your thoughts!
Has he done any videos on micro inverters?
You always get the funniest makes of battery in the US
Nice tear down, wasn't expecting that!
You are adorable and so knowledgeable
I thought this was great and informative and fun!
700,000 subscribers coming fast!
The fact that all cells were matched and voltages were 2.95-2.97 wouldn't bother me much..!! These could be brand new B cells that just didn't pass capacity testing...!! Happens all the time..!!
Perfect for my patio led lights in Arizona
Thanks for your pointed analysis
We accept your opinion !
Love love love your videos! I think these would be good for a boat trolling motor as long as mounted in the rear and paddled.
I have been hoping that you would review this battery! I appreciate the video but would have liked to have seen a load test to see what the actual output was.
I am currently looking at a cheaper than normal lithium battery on Amazon, but after seeing this video I have lost all confidence in the market, so I think I will trade up to AGM. I wanted lithium phosphate, but there is no way I am going there now. thanks for sharing.
Knock of Strong Bad mascot almost convinces me... just for the LOLs alone every time I see the case.
on the amazon site you see they also sell a 100 Ah battery for $70 more and it has a 5 yr warranty.. apparently the 95Ah has no warranty or 90 days.. also something funny when asked about if the cell are new or why they are using 80% capacity cells in the 95Ah batter they go around answering the question with stuff like..
"The Timeusb 95Ah battery that born for RV with UL/FCC/CE/ROHS certificated. and each battery cells from us are ensured with 100% strict
inspection and they are qualified."
what does "they are qualified" even mean.. LOL.. other words they have no clue are don't are wont say..
Still not a bad deal if you just need some cheap batteries for project but getting better cap for little more make better sense to many.. cheap is and always will be CHEAP.. Thanks Will... another great show for sure..
Will, I’ve had this on my Amazon watch list for months, can you do a capacity test just for comparison…much appreciated 👍🏾
I was surprised that the capacity test wasn't in the video.
He wrote it would be a waste of his time.
No harm in asking
95Wh - simply a case of not over-promising? After all, what do we complain about most when testing battery capacities? 😀
If only used as a emergency backup , than I think it will be fine.
Greatings from Croatia 💪💪💪
Crow Ate Ya? :))
Battery longevity and variance of quality at manufacture is still such a mystery to us and probably even to manufacturers to an extent. They are learning, I guess. I salvaged some batteries from a well-used 20 year old laptop. Six lithium ion cylindricals 18650s and after 20 years and nearly as many that they have been zilched by my laptop. Five of the 6 are corroded and utterly unuseaable and one is now powering a converted 2 D cell flashlight and drawing nearly new capacity. Go figure.
You are our new JerrRigEverthing of Solar
Been hoping for Will to do a review on this brand for months.
Remember the “AA battery hack” spoof videos? When he said, “let tear it open” I was expecting a bunch of AA batteries to dump out! 🤣
Thanks again William!
If the case wasn't so large they would be perfect for the average RVer who is only going to cycle them a few dozen times a year at most and only running lights/water pump/propane fridge controller. That price is getting close to the cheap flooded batteries that most people run in RVs.
Looking at the Docan Power website their return policy whether their batteries are faulty upon testing or damaged in transit that the BUYER has to pay full return cost, which is very surprising. For me, despite them having EU stock being in the UK, that cost would be outrageous to return if there were any problems. Making buying from them impossible. Which is a shame as I really like your recommendations. The going rate in the UK for these cells (280ah 3.2v) is £180 each, where Docan Power is $149 (£126) each including delivery. Quite a difference. If you could recommend a UK seller at a more reasonable price I think we here in the UK would clear their shelves. Thanks for your content.
I sure wish that you would have load tested that battery, and possibly even tried it with a substitute BMS that would more closely match the cells.
You mention low temp charging in every video and how you can destroy a battery by charging when it's freezing. So....can you do it? What happens and how does it die?
My guess for the origin of the apparently recycled CATL cells used in this battery is tow motors used in Chinese warehouses. It is pretty interesting that the battery assembler chose to use a battery management system rated at less than 1/2 (of the remaining) C of the cells.
probably those case also recycle from vrla battery
I might not have a problem with this battery if the manufacturer disclosed the cells are recycled. A purchaser naively expecting new cells is probably only going to receive half the discharge cycles anticipated. Paying $50 to $100 US more and getting a new cells is a better deal compared to having to purchase two of these batteries to get the same service life.
I just picked this battery up for 140 on Amazon.
Hi I got 2 200 ah for £269 each from litokola on Ali express and are working great so for the price even if they last 3 years I'm winning I've got a frezzer and fridge and cook on induction and air fryer kettle toaster all on inverter and I never go bellow 12.00amps sitting around 12.3 amps
Maybe for a cheap 12V system in an off-grid situation where it never freezes or for someone who needs a small solar system inside the van they put too much money into to travel trying to make UA-cam videos and ran low on money due to high fuel prices? You never know?
It would be great to see the difference in internal resistance. If they matched that too, then great. If they're way off, then this will become an eternal balancing nightmare.
My guess on the size of the case is either: (a) they got a great deal on that size case, (b) it's easier/cheaper for them in production to maintain all the same supply of parts to build their various capacity batteries.
My only beef with these batteries is that they should disclose WHY these are "grade B" cells. Used or just poor post-production performance "rejects"? It can make a difference depending on the application someone wishes to use them for.
My thought also. Over time the can put almost anything in that case.
It's optimized for RVs that's a standard RV case size. Easy drop in.
Hi will watched the vid. Great info have lifepo4 here in the Philippines for 120 dollars .After watching I decided to buy a more expensive one try to get awa from used cells no guarantee here. Ok thanks
