Glad you liked it!
Your channel is a most helpful discovery! Currently in the process of installing 1000 watts of solar on my motorhome and replacing the four 6 volt lead acid batteries with three 206 amp hour lithiums. Thank you for the easy to understand explanations.
It is good to hear you are taking advantage of the channel's content Tim, thanks for your message. Good luck and have fun with your motorhome's new solar system! All the best, Jesse.
very informative and simple explained!
I'm disappointed that the UA-cam algorithm is only now recommending this channel to me, while I've been interested in renewable energy for the boat I live on for much longer.
Hi Anton, it is good to hear from you. I know what you mean about UA-cam's recommendation algorithm: I am glad you finally ended up on this channel. A tip for you: I have grouped videos per topic category in the playlists. Here is the link to the playlist on batteries: ua-cam.com/play/PL9Nrg1XB1hdjWs1Fo6SHBhs1ag_PQl4Ct.html
Enjoy! Jesse
Excellent overview!
Hi, I just wanted to make a remark on the fact that adding not replacing lithium to your system makes a lot more sense both financially and also for the stability of the battery bank. Lead is a great type of anchor for your lithium batteries. There is a lot to it to much to comment on here but it could be a good subject for another video. Thanks have a great day.
Thanks for your contribution Lavih, you have an interesting topic there. I agree with you: A great idea for a dedicated video. All the best, Jesse.
Your videos are fantastic Jesse. Thank you so much for the work you do.
Glad you like them Corey!
There needs to be an extra big like button for this video. Thank you. Great information content with no BS. The best of you yube.
Glad you enjoyed it!
Great Video. Just the info I needed for my RV.
Glad it was helpful!
Great informative video on Li and Lead Acid battery. I'm still wondering if you can just drop in a LiFePhosphate battery (easily found in Amazon) in replacement of a UPS Lead Acid battery. your video talked about adjusting charger. but you cant do that with a UPS.
thankx
Thanks for the great information Jesse 👏👏
You are welcome Peter, it's good to hear you appreciate the video! All the best, Jesse.
Hi Jesse thanks for the info.My area of concern is that I want to use a LifePo4 battery with an inverter to power studio Flashes outdoors. Could I just connect and forget?
You think and speak with tense authority. Captivating, ... I admire your editing, your honest delivery. How do you manage your
Hello Mark, thank you for your message. I am glad to hear you enjoyed the video. And such a great compliment to receive, thank you. It seems like you wanted to ask a question, though it is interrupted halfway the sentence?
Jesse
Brilliant explanation!
Glad you liked it!
I just acquired four 12v 100ah lithium batteries. I want to run them in series since my bushwhacker plus teardrop travel trailer is a 12v system. My question is can I just drop them in a place they fit and travel like I did with my one 12 v agm battery?
Great videos! I'm gleaning as much info as possible before I purchase the components for an RV setup. I've watched your dc-dc video, but I'd like to run a 24v lithium 'house' battery and couple it to the 12v starter battery, via an external regulator. Is this even possible..... and if yes, what additional wizardry would the setup need? I'm hoping that I won't need an additional 24v alternator!
Hello Mark, thank you for your message. Did you happen to see the video on dual battery banks in vehicles yet? I think this will be useful for you: I pasted the link to the video below. Enjoy! Jesse

Great video with very helpful information. Just wondering how you can tell which Lithium batteries are high quality verses poor quality. What should I look for thanks? Chris
Hello Chris, thank you for your message. It is good to hear you found the video helpful.
As for your question: There are several different ways, though two good sources of information are the datasheet and the warranty policy. The latter is in my opinion an expression of confidence of the manufacturer in the product.
Good luck!
Jesse
Thanks again!
You are welcome Ian, it is good to hear you appreciate the channel. All the best, Jesse.
Thank you for the video. I have a question for you. I have two 100 amp hour lithium iron phosphate batteries with built in BMS in each battery. I have converter/charger that is 14.6 volts constant current and constant voltage. The battery manufacturer recommends 14.6 Constant current constant voltage. My question is when shore power is available can I leave the charger on long term? Most of the time this RV is off grid but in the rare event I have shore power can I leave it on? Thanks
Hi there, welcome back! Your questions make a lot of sense: There is a video I shared where [amongst other things] I discuss the charging cycle, current and voltage behavior. This might be of interest to you, here is the link that brings you straight to the right point in the video:
ua-cam.com/video/TAEzCcayI0g/v-deo.html
Let me know whether this answered your question! All the best, Jesse.
Thank you for this absolutely amazing tutorial. This was very valuable. I have Motorhome and I want to upgrade to lithium batteries. Lion energy says these are plug and play batteries. Others are telling me I need a DC to DC charger to avoid damage from the engine alternator. What are your thoughts?
Hello Roark, thank you for your message. It is good to hear the video helped you in your research. In response to your question: This video describes different configuration options with DC/DC chargers connected to your alternator: ua-cam.com/video/TAEzCcayI0g/v-deo.html ['Deep Cycle Battery Charging with your Alternator...']
Enjoy! Jesse
Really enjoying these informative videos. Do Lithium Batteries go through a bulk, absorbation and float, like Lead Acid? I believe I heard in a past video that Lead Acid could charge relatively fast up to 80% but the last 20% (Absorbation) was fairly slow. Is this process the same with Lithium?
Jason
Hi Jason, it's always good to hear from you. You are correct to assume that Lithium's don't have the same multi-step charge algorithm as Lead Acid batteries. Conventional equipment can be 'fooled' into treating Lithium batteries correctly, by setting the settings correctly [e.g. the temperature correction factor as mentioned in the video]. Most modern equipment already has Lithium-ready charge settings as preset values.
I guess the piece information I am after is can a Lithium be charged at the full amp output of the charger all the way to 100% or does it tapper off after 80% like lead Acid. For example I have a 40 amp DC-DC by Renogy it pumps 40 Amps at my AGM until it hits 80% then it goes into Absorbation and that last 20% can take awhile. If I switched to Lithium can the DC-DC pump the full 40 Amps at the battery all the way to 100%? I know this is a question for Renogy but I have called their support before and I wasn't very impressed with their knowledge.
Jason
@@PrimalOutdoors Typically, a Li-Ion battery charger does do BOTH a Bulk (CC) Mode and an Absorb (CV) Mode. But, the Absorb (CV) Mode for a Li-Ion batteries is much shorter vs a Lead Acid battery. Typically, we do NOT ever try to get to full 100% SOC with just Bulk (CC) Mode
@@vtorsi610 I appreciate the reply, I think I will be switching my AGM out to a Lithium very soon.
Jason
Some good points here. However, although you mention temperature in respect of not needing to monitor temperature while charging with LiFePo4 batteries, I believe that you didn't mention the fact that LiFePo4 doesn't like to charge much below zero. In northern European winters, you can have single digit sub zero temperatures for quite a few days at a time. This would mean that in cold weather, lead acid, which can happily charge away at down to -20C, would in this instance be far more useful. I have looked into this for remote automated weather stations. For anything that doesn't need portability, SLA has a significant benefit in this regard.
So are the temperatures in the engine compartment not a concern then for a drop in replacement Lithium battery from a FLA?
I was under the impression that the cold cranking amps of Lithium are enough for cars but would hurt the battery potentially. I'm not sure if that is true tho. My plan, right now it to make a capacitor boost pack for the lithium battery to replace my FLA in my minvan.
Perhaps I don't need to worry about the boost pack or the temperature of the Lithium battery in the engine compartment. I live in Florida so I don't deal with freezing conditions. Thanks in advance Jesse!
Thank you
You're welcome
Dear Jesse, I currently have a grid-tied system, but I would like to improve my backup. It currently runs on lead-acids, using a fast acting relay to switch lights and computer to off-grid in case of a blackout. The inverter is always on, and a conventional charger keeps the battery floating despite of the idling inverter consumption. All is well, but the life span of the lead-acid battery is not very satisfactory, even though it is just sitting there most of the time, so I thought I could use a special charger to keep a lithium battery charged and the inverter running when utility is up, and switch to off-grid during power shortages. Is there a way to modify a charge controller so as to use also a couple of solar panels just to keep equipment running during an all-day long blackout?
Hello Chava, thanks for your question. Sounds like you have a nice backup system! Running a grid-tied battery based backup system with additional solar power is often done and can work quite well. If you need specific recommendations, you can contact me through www.solarsolution.co. You can also ask other UA-cam viewers for recommendations, I know of several other subscribers who run similar systems. Good luck! All the best, Jesse.
Great sensible video and you didn't ask for people to subscribe and ring that damned bell - So I did anyway as I'm moving soon from 8 year old solar charged AGM's to lithium on my yacht in the Caribbean and need a sensible plan for my 300A 24V house-bank system and a completely separate 12V lead acid system for starting and not burning my alternators out
Your message made me smile James, thanks! And welcome to the channel. Good luck preparing for your lithium upgrade and enjoy the islands!
Hi Jesse. Thanks for the vid. I have a small ultralight airplane that sits unused from week to week (especially in the Winter)! Weight is important so I replaced the original lead-acid battery for the starter with a Lithium Ion and saved about 5kgs. I hooked it up to a pair of solar panels but I guess that maybe I've not made the correct selections on the controller because it's been losing efficiency steadily. This is annoying because I need a strong, reliable cranking power to get the engine spinning! On viewing some YT vids, others have said that 'trickle charging' an Li battery will kill it over time...and I guess that's what a solar panel does! Am I correct? Thanks.
An ultralight! Wow I envy you, that's great. And the 5kg weight reduction is quite amazing. Thumbs up for Lithium. What you are intending to accomplish is definitely possible, just make sure to use the right equipment and settings. I'm sorry but I cannot provide you with personal advice through the UA-cam comment section. If necessary, you can get in touch via www.solarsolution.co/contact. Good luck and all the best, Jesse.
I have an old solar system set up, my mppt solar charge controller doesn't have an option for lithium. It only have AGM, GEL and LIQUID. Can i use it for my lithium? If yes, which of the battery should i choose?
Hi Patrick, thanks for your message. I suggest you start with verifying whether your MPPT Charge Controller has configurable voltage settings for the different charging stages.
I’m getting ready to install an off grid solar system. I’m using an AIMS inverter/charger which on many suppliers’ websites is compatible with lithium ion batteries however it is not an option in the settings of the charger. I’m having trouble finding out what I should set the charger to in order to charge my Lion Energy battery bank from a generator if I have a streak of overcast skies and the solar charging is insufficient. Can you please advise?
Hi Matthew, thanks for your question. I would be happy to help you with personal advice: You can find the different options at the main website: solarsolution.co/services/
Another video which might also get you useful information, is on the battery charging voltages, did you see that one yet? Here is the link: ua-cam.com/video/87rxYyTZgbE/v-deo.html

Hi Jesse I enjoyed your tutorial, I have questions for you, I have recently changed my AGM for a lithium - ion - phosphate should I renew my inverter for one that is compatible with a lithium battery. my system is wind only connected to a charge controller straight to battery and direct to inverter
Hi John, thanks for your message. It is good to hear you enjoyed the video. For personal support, you can contact me through www.solarsolution.co/contact
It depends on if you can live with the limitations mentioned in this video such as the fact that your inverter probably won't know the true state of charge of your batteries and the low voltage shutdown will probably be wrong.
Hi, can you change from 24v gel 100ah to a 100ah lithium in a trolley inverter, I'm from south africa and we have major loadshedding (power cuts for 2hours ).
Really like a help on this please
Because of system growing, I now have 3 charge controllers in my small off grid setup, one nice mppt 20A and two cheap pwm 20A. I know its undesirable and ugly, and i will need to dial in special settings on each if i go to lithium, my worry is max charge amps. I see 'max charge amps' of 20A on the battery i am looking at and recommedation to only use their charger, but in full sun im putting out 50A potentially, what battery/bms could handle this kind of input? It works fine with lead acid currently, just low capacity.

I bought a plug and play battery bigbattery and I want to hook it up to my new truck camper. My truck camper has a led acid battery that I don't want to use. I also bought a lithium battery charger to charge the battery inside the house and just put it in the truck camper when I travel. But in case that I need to charge the lithium battery using the inverter in my truck camper, its is possible to do it? would this hurt the battery? I hope I hear what your thoughts are.
Hello Cookie Cracker, thanks for your message. As for your question, I would like to draw your attention to the pinned comment at the top of this section. All the best, Jesse.
It's 2022 and some Lithium batteries say "built in BMS, is that sufficient?
If I use a battery separator both will be 48v but 1 Bank is 255Ah and the other is 40Ah and with battery separator do you recommend ?
Hello Mark, thanks for your message. As for your question, I would like to draw your attention to the pinned comment at the top of this section. All the best, Jesse.
Dear Jesse, I really appreciate all the information you are sharing. I am using AGM batteries and I am afraid to use my NOCO repair mode on it. It is okay to use this repair mode with my AGM batteries? Thank you for answer!
Hello David, thank you for your question. Have you compared the battery recommendations with your charger settings yet?
@@SolarSolution Hello, Jesse! Well, i bought "MIGHTY" batteries and have no much information... My NOCO battery charger instructions, don't provide enough information about this topic.
Thank you for your time, I really appreciate it.
Hi David. The information on the charging voltages from the NOCO charger are rather essential. You might want to consider to contact the manufacturer to retrieve this. Good luck! Jesse.
ive seen many people using li-ion batteries in racing cars or even regular cars mostly because of the weight reduction. would that be ok to use?
Hello @Comedyman112, thanks for your question. This video discussed several aspects which should be kept in mind while considering replacing conventional lead acid batteries with Lithium Ion batteries. Could you clarify which aspect remains unclear?
Thanks, Jesse.

Dear Jesse,could you help me.I have an electric cabin scooter, which has five led acid batteries,i want to reolace them with Lithiumion phosphate battery, could you recommend one.My scooter has two 1000w motors 1000w each wheel.It is 60v and 52Ah the batteries. Thanks.
What can be done with vehicle charging the RV, as lithium will draw way more than the lead acid, and consequently burnout my vehicle alternator?
I was trying to replace my Electric ATV's 1500w 48v (4x12v20Ah lead acid) battery and I was wondering what LiFeP04 battery you could recommend to replace my old acid battery. Any help would be greatly appreciated.
That sounds like an exciting project. I would need additional information in order to give you the right advice. I offer personal advise through consultation services available on the main website: www.solarsolution.co
Good luck with your ATV! All the best, Jesse
Jesse;
Great videos.
On my catamaran I have 6.2KW of agm(Victron) house batteries, 2ea 80Ah gel engine starting batteries, 2 each 125A alternators all combined with a Victron multiplus 12V/1600VA/70A inverter/charger(all professionally installed). I would like to add in parallel approx 5kW of Lifepo with integrated BMS.
My theory is that the BMS on the lithium batteries will allow the lifepo batteries to charge or discharge until it reaches the high or low voltage cuttoff and or high current cutoff. So basically just add the Lifepo to the agm in parallel and let the bms protect the Lifepo. Due to the charge/discharge range differences between agm and Lifepo I know that I will lose some battery capacity.
What do you think.? Am I missing something ?
Hello Mark, thank you for your [excellent!] question. I know there are a few videos on UA-cam, discussing exactly this topic. Have you watched them yet? Clark from 'Emily & Clark' has a nice video on this.
@@SolarSolution Hello Jesse; Yes I've seen Clarks videos and even bought his battery bank manager. Also acquired two Wakespeed 500 units, Victron Cerbo gx, shunts and smart battery monitor and will assemble it when I get back on the water this summer. On a separate note I have acquired blade battery components for a 48V 7KW Blade battery w/ bms to combine with my chevy Volt 18kw NMC batteries for off grid Colorado cabin.
Thank you for making these videos
Hi I upgraded my lead acid batteries to lithium, I installed them where the lead acid batteries were installed right next to the motor in my motorhome, the motor puts off a lot of heat, my first trip out with them it was 100° out plus I was running my generator as I was driving,The generator compartment is right next to the battery compartment and the batteries got super hot but they never shut down,should I re-wire and move the batteries to a different compartment?
I've bought a 12volt 100ah lithium for my RV replacing a lead acid. It's supposed to be a "drop in replacement" battery with a built in BMS. Can I assume the BMS compensates adequately for the original charging system?
Hi Burt, thanks for you question and congrats on your new purchase. You can contact me for advice through www.solarsolution.co/contact
No. The bms acts a little like a circuit breaker to protect the battery from extremes but it will do nothing to stop you from killing it slowly with improper charging etc.
@@SolarSolutionBurt Hulbert's question seems like an important one for all of us to know. I for one have always questioned what 'drop-in replacement' really means for the consummer. Why not provide a public answer?
I would like to change my Lead battery to a LiFePo4 in my Nissan Leaf 2016. Just doing a deep research into the swap
In the video you appear to quote a Lithium-ion battery voltage of 12.8. My understanding is a single Lithium-ion cell voltage is somewhere around 3.8 or 3.7 volts. Three such cells in series suggests a voltage of 11.1 or 11.4. I'd be interested to know what combination of Lithium-ion cells could result in the 12.8 volts you quote?
LFP is nominal 3.2V x 4 = 12.8V
I just bought a lifepo4 golf cart battery and a 10amp lithium charger

• Why does my invertor with a 70 amp charger stop charging around 50% for the lithium when the flooded batteries charge down to 10 amp before stopping
Hello Mike, thank you for your question. How are is your 50% SOC value calculated, and what are the charger voltage settings?
• When the bms trips how do you rest it
Hello Mike, thank you for your question. This depends on the type of BMS used.
• And why does the charge controller quit working and needs to be rest when the bms trips for low voltage
Hello Mike, thank you for your question. This depends on the type of BMS you are using.
• How high can the voltage charge to for the lithium
Hello Mike, thank you for your question. This depends on the type of Lithium battery used.
okay video but could be better if there’s visual diagram like other videos about solar. hoping for an improve presentation.
Thank you Nick, I think that is a good idea. All the best, Jesse.
1 bank is Yinlong 2.4v LTO and the other is 3.2v Lithium Phosphate!
Hello again Mark!
Thanx best video I seen on this subject so far. Some questions in the comments
Thank you for your message Mike, it is good to hear you enjoyed the video.
Should compare to AGM, not flooded lead acid
"because lithium allows for much higher current". I'm under the impression that in most cases lithium iron phosphate batteries actually provide a lower current than lead acid batteries. Unless you're using specialty batteries like headway. Most lead acid batteries can provide over a hundred amps while your average lithium iron phosphate 12 volt provides around 5 amps per cell in a four cell series configuration. Where is my misconception?
Thank you for your feedback and question Patrick, this might be an interesting topic for a separate video. Thank you for the suggestion. All the best, Jesse.
Where is your proof that you can only draw down a lead acid 50 percent?
