Thank You , i am the solar man of Lehigh Acres Fl and thanks to you i am now building
my Plug N Play Solar Boxes with Lithium Batteries. It will cost more but i believe that
it will be worth it when you figure 90% discharge rate.
Bob, do you do consulting?
So much value in these old Leafs. You squeeze every mile you can out of the vehicle and then take it apart and it's a powerwall for your house, plus motors for other projects.
The $64,000 question is ... How long will these very used modules last? 1 Year? 2 Years?
@@vtorsi610 Cycle life is determined by temperature, and depth/speed of discharge. If you operate a Leaf module capacity bank within that sweet spot, they actually deliver incredible longevity. ua-cam.com/video/hjJh4nJ3I44/v-deo.html Here is a Leaf with 210k miles on the original battery. Staggering longevity and performance when operated within ideal parameters
@@InnovativeSustainableSolutions Yes, we all know ... if you barely use the battery it will last much longer. But, your reply does not answer my question. Most Off-Grid homes, do actually discharge their battery bank, sometimes severely, on a daily basis. The seller has no idea what temperature these USED Nissan Leaf Modules where exposed to, when they were inside the vehicle. Or how many cycles, were already extracted. Or the min, average or max % DOD used by the car. The seller has no clue how many more CYCLES ( even say @ 50% DOD ) remain in the pack. How can the buyer make a wise decision when there are so few facts available? The only fact we have is ... the pack is already severely degraded down to 60% of its Original Capacity. 40% of the original capacity is gone forever!!! With only a 30 day warranty, this is a crap shoot and maybe a huge waste of time and money. At just 50% DOD daily how many more CYCLES can we get? I hear crickets! A Battleborn battery is guaranteed for 100% DOD every day for 10 YEARS !!! And then in 10 YEARS my Battleborn battery will be a USED pack ( for "FREE" ) that is equivalent to the above pack. So, why would I pay for a USED battery pack today, with essentially no warranty, when my new Battleborn will become a "free" USED pack in 10 YEARS? If this USED Nissan Leaf battery pack cannot be used at 100% DOD ( 38 Amp-Hours ) daily for at least 6 YEARS, or 50% DOD ( only 14 Amp-Hours ) daily for 12 YEARS, then a Battleborn is a CHEAPER purchase. This USED Leaf module ( with falsely advertised "100% Capacity" ratings via the ebay link ) is no bargain ...
@@vtorsi610 I know a little bit about off grid power, and heavy discharge cycles (I will cite my channel as my resume). I would respectfully postulate that you are overcomplicating the calculation by trying to guess what kind of abuse the Leaf Pack went through before you bought it. For the purposes of a DIY home powerwall it really doesn't matter. This is because the FUTURE degradation of the battery is what matters to the purchaser. And that is determined EXCLUSIVELY by the conditions we (the DIY home powerwall folks) expose the battery too.
To answer your question about how many cycles you can get out of a Leaf module (Gen1 chemistry: lithium-manganese-oxide with nickel oxide) the answer is around 5,000. Rougly 60% the cycle life of the LiFePo4 chemistry used in battleborn batteries. So Battleborn batteries are BETTER than Leaf modules, but are they cheaper in the long run?
I Leaf battery pack off Ebay will run you 1,000-1,100 dollars and have a capacity of 10-14kwh. We'll go with the underperformers and say 10kwh. Properly maintained (cooled, and professionally bms'd) you can get years of heavy daily use out of this pack, but honestly, I advise people to not even start until they can afford 2 or 3 packs. So we're out $3,500 and we have atleast a 30kwh powerwall, that can give us 3 years minimum (probably 5) of 90% DOD. Most of us off-griders are not rich, so I realize a $3,500 powerwall is a stretch. But compare that to a Battleborn bank. A 30kwh system would run you $30,000. Sure it would last twice as long, but it would cost you 9X as much. I'm not a huge Jehu fan, he's been pretty rude to me before when I was just getting started and asked a stupid question, and I think Battleborn's are good batteries, but for cost comparison in the long run, for large powerwalls: The Leaf packs blow them out of the water.
awesome time lapse video at the end, with clear view of the stars in the sky. wow.
I have a 2011 LEAF with a 2016 battery, perhaps these and crashed cars are some of the sources. 😀
Warranty upgrade to 30kw seemed possible on pre 2018s
love you from India man!!
I saw your couple of videos
you have so much knowledge for 18650 battery or other batteries
Appreciated. Also, totally off topic, but beautiful Telecaster.
Can you please make a review for that battery workstation, it look so cool.
Thanks a mil finally a video that tells it as it is
on the Leaf batteries. I am new to this so the tutorial helps! All aroundgreat.
Thanks for testing these. I'm looking into building a powerwall and my source of 18650's has dried up and I only have about 500 useful cells out of the 1300 I got. I had been looking at these exact cells as an easy option since it's just a few bolts and not 1000's of solder/spot welds. I'm sad to hear that they could already be 50% degraded. Not worth the money at that level, if they were better, then I could see them being a cheaper alternative to Tesla modules.
Thanks for the video Jehu! May you make a video comparing this pack with a Tesla capacity and price? Thanks
All of the provided buss bars, covers, balance lead lugs and even the terminal bolts are original Nissan leaf pack parts. Compression plates including ones with welded nuts are built into the pack. Its a treasure box of parts.
I own a 2014 Nissan Leaf and it's great, wonderful to see these batteries used for other things
I like how you shorted terminals and didn't cause a boom at 2:08
You r the king of li-ion battery
The Li-ion King, indeed.
0:00 Awesome UA-camr growl art!
Hey Jehu, Your Videos are only getting better and better!!!Love this for sure!!!
The hemp rope handles are killers! :D
I already have a wrecked leaf bit it would be great to have the containment system.
Hmm... So what if I subscribed and hit the bell button then what? Just kidding love your stuff! New Subscriber...
Thanks for the great video!
JEHU... learning so much from you!!! Thank you very much for your content sir!
I have been trying to fins a 12s lipo battery checker, only looking to read the voltage on each cell
great video, just one question if used without a BMS what will be the end result?
what charger/inverter you recomend for houses ?
Hey thanks for the video. Actually I want to ask you to check and correct those links in the video description as they are no longer working..
Have you done any reserch on reconditiined fork lift batteries fi sollar systems
Hi there!
Thanks for your impressive video. Can you tell me a charger I can buy for 48 volt lithium ion batteries with 24khw? In other words, entire leaf batteries.
Where are the accessories shown available?
Specifically the orange plastic plate and bms?
Ty very helpful vid.
Wondering if i can put a pack like this one on an ebike. Any suggestions?
Very interesting and pedagogic video ! I will go to build this !! What will be the recommended voltage and current to charge this 48 v pack ? What kind of charger … does it need to regulate the voltage and current ? Or the BMS does it ? Thanks and regards.
Let us know how many more cycles you get and your % DOD ( like 50% DOD ) because these GEN 1 batteries are already severely degraded !
Is it necessary to use a bms when using two Nissan Leaf modules for a 12 volt application?
Good Morning. I was thinking of a 12 Volt sys in a trailer that has solar power. What do you think of that and do think the cost over AGM batteries? Jack
Any updates for these links? I can't find any source for these kits!
Great videos.
do you still have those uni solar flexible solar panels? or can you get me a good deal on a few for my camper. i may need to live in it soon.
Can you help me find good 2400 mAh sub-c batteries to rebuild cordless power tool packs? I've made some purchases on ebay and amazon but they were wayyyyyy below rated capacity.
Those batteries are stacked with spacers in the leaf battery so when bolted with the all thread the pressure is spread across the top and bottom edges and not on the center of the cells. This allows for some pouch expansion and contraction with heat and avoids pressurizing the pouches by compressing the pack. Perhaps you can source the spacers with the cells? It would be safer.
Hey bud I was wondering what you would say is a good or maybe even the best all around charger for large/normal size batteries. I like the way this one in the video looks. I'm tired of these crappy hobby chargers off of eBay and Amazon. Thanks ahead of time. Peace.
Podrias hacer los videos tambien en español ? por favor.
these are super neat. any of these kits available elsewhere from a reputable source? current link doesn't work anymore.
If you haven't already, maybe revisit these batteries? I have seen other videos where the used leaf battery packs have between 70-90 percent of their original capacy and the price is much lower.
Good video Jehu, thanks for sharing
Love your videos.
@@sbollmeyer thanks Steve :)
@@OH8STN , you're welcome.
Great music intro ;)
What is a good, not too exspensive charger that's good for the Nissan leaf batteries? Any help greatly appreciated 😁
Where did you get the battery discharger / reverse charger?
How much longer are they expected to last or cycles ?
Shame cost is so high. Nice video fella.
Could you please test a Toyota aqua hybrid battery I would like to buy some and build a solar system with them, plus it's more easy to get aqua battery over 18650 battery in my country. Thanks
thank you
What would be a good AC power supply for this BMS to charge this project?
great kit!
How many more CYCLES do you think a GEN 1 kit will have?
I'm interested in the Sam's 68ah to kecskemet
Hello friend, excellent video, where could I get cells for a 27kw battery of a kia soul ev from 2016?, I have some damaged cells
@jehugarcia Tech Direct doesn't have any of this kit available in their ebay store. They have the cells, but dont seem to be selling the fancy metal brackets/box/bms.
All I ever get from them is the modules regardless of what is shown in the ads. Buss bars or brackets are never sent, they refund instead of offer the brackets you see on their Ebay pages.
CncObsession good to know. Thanks.
Please review lg chem batteries
Can we still get the kit? Where can I get the orange top bus bar connector? Thank you!
Is it possable it direct charge my new bmw i3 ev direct from a solor panel without going through a A/C conversion and then back to DC through my household power?
your car is 400Vdc most likely so you will need some kind of conversion unless you have a matching solar system volatge
wait wait wait... are half of the leafs in the US? because i think Norway has the rest then :P
Is this BMS made specially for Lithium Manganese batteries like the Leaf-batteries are. Or does any BMS with 14s work?
I want to build a 84v one for my ebike
if your wires are getting warm, you're doing something wrong a 40A fuse does not a 40A rating on the wire make
Love your video.
Subscribing.
Question: TigerDirect pairs a 48V charger for their 7 cell packs. Is this enough to charge these which are 7.4 volts each? At nominal 3.7V each cell, 14 cells is 51.8V. Did you charge the 7-pack with a 48V charger? Will the BMS you installed on the pack handle a 56V charger? This would make more sense since 8.3v is max. rated capacity and 8V would put it under that.
Do you have the specs on the CHARGER ?
If you were worried about efficiency would you use higher gauge wire so it doesn't get hot and use power to make heat?
If you wanted more than 40A continuos yes, but then again you’d run out of battery in 40 mins
If it gets hot/warm at all that is energy lost. A slight amount of heat can be huge in regards to Efficiency. If you are going to use these for a powerwall, for sure, use much bigger cables. Whatever size wire anyone tells you to use, double the size.
Anyone know where I can get a BMS for these leaf modules ? I want it to work with my Magnum Inverter charger. I have it set up like 14s.
Do you or anyone on this channel have any recommend series of videos for me to follow in designing and building my own solar and battery system at home? Maybe a playlist? I got a quote from a company for 30k and I just cant see affording that at this time so I wanted to design and install my own system especially if i can make it more modular and add to it over time instead of one giant system at the start. What I would like to do is not have the system net meter and store in batteries then use that and only use grid when the system cant provide enough juice. The installer I got the quote from said if I net meter ie grid tie that if the power goes out I would not be allowed to use my solar because they don't want it feeding into the grid if people are working on the lines.
I assume 10 modules are needed for 72v application?
How to build 144v 85Ah battery for curtis Ac-76 motor? And recommend bms and charger?
Please reply..
Regards! 🙏🙏🙏
From India.
Using ncr18650b /ncr18650ga
What type of Lithium Ion is this battery?
Poly?
Phosphate?
Really should measure the voltage on the bus before you plug it in
What brand tape?
Thanks for the video. I just purchased a complete package with 48 modules for my solar backup. My inverter can run from 10-16v systems. Do you recommend that I refrain from discharging all the way to 10v? Another video led me to believe that the sweet spot with these is between 3.6-4.1 per cell. If I set up my system to stay between 14.4v-16v, will they last longer? Does discharging all the way cause any harm to the batteries? My goal is to make them last as long as possible. I have a 7750w solar array and a 3600w turbine setup. I live in yucca valley where I have no shortage of generation. I currently have a bank of acid marine batteries that are about 5 years old and are wearing out. I simply just refrain from using much power after dark. Do you have any ideas on how long they will last if I start using them after dark? Should I stick with propane water heating and wood stove for inside the house?
How is your mind turbine working, also which model is it?
Hi, could I make 2x24V from 7 cells?
I cant find where to take this BMS
Hi what s the different between Nissan leaf bat and Samsung bat ess
Which one the better
Do you think the jkbms with 2 Amp active balance would be a.good choice for a leaf battery. I have 24 cells set up in a 24 volt configuration and have been using it a year with no bms but people say it's dangerous and that I need a bms. I ordered a jkbms and I hope it works for what I need
I love the design of the cell. But your right about the cost. How many cycles will the pack go through before you notice a performance degradation is noticed?
1 cycle. Doh. It is subjective, and whatever it is worth it, depends on a size, over size, how deep you discharge, exact price (plus BMS price and mounting), what was the capacity they were initial at, temperature, etc.
... nice edited video :)
are those with 18650 cells inside?
Can you repair them or regenerate them?
How many of these modules can make 300 volts ?
What is the total cost for that pack? The links in the description don't seem to include the brackets and bms, just the cells. Also would you say that 2kwh is the theoretical max of new cells or measured capacity of 50-60% degraded cells?

Great video.... I'm looking for the link to the kit you assembled in this video which includes the batteries, BMS and the chassis. I do not see that setup referenced in the any links in the description of this video. Can someone help me find it?
Todd Wahl go to Green Tech Direct on their website and on eBay. I got mine on eBay.
Hi, can you please recommend a 48 battery pack for portable use with ham radio use - need about 20ah capacity atleast and 30amp discharge rate. about 1 hr run time would be good
10 @ 18650 cells connected in parallel is about 20 Amp-Hours. Then connect many of these parallel groups in series, to get 48 Volts. If you decide connect 4 @ 12 Volt 20 Amp-Hour batteries in series, first verify that the BMS can actually handle 48 volts. Then recharge the 12 volt packs as 4 separate 12V units.

Nice video. I have a question. Can I build a 3S battery bank with Leaf modules? For an example let's say I have two leaf modules. Can I build a 3S2P bank with them?
If you only have two (2) Modules ( 4 Cells ) then no you cannot do 3S2P cells = 6 cells, because you only have 4 cells! You can do 2S2P cells.
Could do a video on 24v solar home system using electric car lithium batteries
I see where they have the pack of 7 batteries on the vendor ebay store. Do they also sell the kit you used along with the BMS and the metal box you used in your video? I don't see that in their store.

Hi there. I’m looking for the bms kit you used in this Nissan Leaf battery all links fail ? Can you help pls ?
How would you parallel connect 2 of these batteries with each having their own BMS?
Glenn Pearson yes
parallel dont matter just have a way to hook all of them up via distribution block make sure all battery packs are close in voltage after that they will match up on their own I have had no problem doing this. If its a good BMS and you have one pack dead and one full charge then charging will the dead pack will start if its with in the current rating. This is one way i test the bms boards i purchase.
@@battery_solar_ev Slightly badly written
@@battery_solar_ev ... I do not understand this please explain in different sentences
Is there a new link for the kit?

Hey jehu,
would you mind to ask to Community whats the batterysituation for used batterys/packs around the world like ?! I am especially interested in Germany and neihbouring countrys.
the questions could be like; Is it legal to sell battery without protection? Where can I find a good deal ? and so on.
A new videoseries called" Batterys around the world".
that woud be interesting to see.
I live in Germany and as far as i know it is legal to sell any type of battery as long as it is as parts and not as a finished product.
The problem woud be delivery in large amounts since the transport company will have to do some safety checks.
Sadly as far as i have searched over the last 2 years there are no reliable and cheap battery sources like in the us right now.
The area I live in in the United States, the local scrap yards refuse to sell them to me. Cash in hand but will not sell them. It's legal but someone else must be getting them.
@@kevinroberts781 Germany has one big Problem..... Useless Laws.
Im really good at repairing pretty much any electronic device.
My local junk jard has containers full of laptop's and really extensive flat screen televisions.
But it is forbidden by law to re purpose anything that people have brought there.
Even if someone woud throw a 3000$ PC in there you woud get sued for stealing if you take it out.
Actually guys, living in Finland, I get most of my cells from Germany. "Shop dot Lipopower dot de". They don't sell used cells, but they have high quality cells at a good price. It's also possible to get sales from the Netherlands or Czech Republic, but in those examples you almost never know what you're getting. I know there's a big market for repurposed cells, but new cells are pretty reasonably priced for a big project with long lifetime. If I'm just building small DIY projects, maybe the new cells are too expensive for some. If I were back home in the US I would probably consider some used batteries but not here in the EU
Yes I plan to buy a 48 volt can a guy hook more then one of those batteries together like 2 of those 48 volt modules?
You can do 2P 7S. So you have 14 modules. connect two in parallel and the 7 of those in series to get 48V. Good luck
I'd like to know about the expected life of these batteries, this is needed to judge economy.
Jehu - - - how many cycles can you get out of these? That's an important number for solar! (1 cycle = 1 day). I know they're listed as ~70% - but that's voltage, not remaining cycles!
(anyone??)
Right, but we need some way to relate cycles to the number "70% capacity" that sellers give these batteries.
@Dennis Jemison How long has your used Nissan Battery Bank actually been operating? How man CYCLES have you put on it? How much has the capacity degraded?
@Dennis Jemison These batteries have already LOST 30% of their capacity! And now you say we should not charge to 100% SOC, nor Discharge down to 100% DOD? Lets say we charge up to 80% SOC and down to 30% SOC. So, we now only get 50% of the already reduced 70% = only 35% of the original capacity - How is that a DEAL ???
@Dennis Jemison These are ( severely degraded - old style ) GEN 1 Packs, not the ( new style ) GEN 2 packs. Therefore, you did *NOT* buy what is being advertised in this video ... So, take your irrelevant BS and shove it, yourself ... I love it when idiots, like you, don't even watch the video ...
So... the way it looked in the video was as if this was a company product. The link Jehu is providing goes to an eBay sale to something that *looks nothing like* what he had in this video...
*Am I Missing Something?*
