What size bolts or such do you need? Any pictures of how they interconnect? Trying to make sure I fabricate / buy bus bars and bolts ahead of time so I can assemble everything asap.
If you find a way to ship to Europe or the UK as a group buy setup maybe then that would help sell a lot of units, probably a 20ft containers worth at least.
I think I figured it out, these are likely cells manufactured by SK innovation for the Hyundai Kona. These were likely slated to go into the Kona's but then once Hyundai recalled the Kona's with SK batteries, these would be sitting unused. Now they are being liquidated, and there's a good chance you face a higher than normal risk of fire using these. If you do use them, I'd advise having them in a shed and not being used inside the house. For me, it's a risk I'm not willing to take.
@@tkswdr I understand that, but the Kona is a pretty low power car and they were catching fire at under a 3c rate. Thats very low for an NMC pouch, it's a manufacturing defect.
Yes; what happens is that the 3P could come loose if I recall correctly. So then 2P gets the juice from 3P. In our hybrid setup we pull 25Amps at max. So I bet they don't even come loose in the first place.
but are these really LFP cells ? So far I am aware of LG Li Ion cells from the surplus production they had produced for Kia and Hyundai vehicles where the batteries had been burning and LG had to pay for the fully exchange at least inside the EU. I am not thinking that these are the used ones from those exchanges cause usually insurances have to pay for that which then start to destroy them. But the meanwhile surplus production that did not make it into the car and had been produced by LG might end up anywhere , also the spare batteries they had to have in stock with the then outdated design. I guess it has been a LiIon battery pack and no lifepo4 one cause LG is slowly moving to LFP
Can't wait to see these! High capacity with form factor.. makes me think all kinds of new products. Thinking an extremely compact chair with primary cells on TOP of drive system as well as the chair itself containing at least 50 percent of total capacity . . Hell even a head rest can take a huge pack of these stacked in with things designed around them . . 50mile range, big wheels but low to the ground, extreme low speed torque and still max out maybe at 10mph , toss on a nice controller with fast charging and sexy control joystick multi OLED interfaces I'd want one if I couldn't walk.
I don't know about putting these outside of a metal box.....not to do the "OMG NMC go boom" thing but a headrest? No thanks. I'd only trust LTO that close to my head if I was disabled.
Jehu man I love diy yes turn key is great but to me DIY IS MUCH BETTER…The feeling of just making your own packs …don’t mean to sound lame but your the reason I do DIY batteries.. If I had money I’d buy 4 of the sonata cells 24v ..you are the 🐐🐐🐐🔋🔋👑👑💯
Hi, if I get the pre-order cells will there be a guide or video to show us how to setup everything for a solar system or will we have to piece info ourselves from YT and google?
Would love to test this with my future house I'm building. I've got plans for what I think I need to build a good size rack mount pack system for my place in Texas. This seems like a must simple solution for my needs. Going to plan new design around these LG's and see what I come up with. Love your video's.
I still watch your channel, even though im in Canada, Love this module. Maybe you need to think about an annual warehouse sale? Get some shelf space back, some cash.
I have a 96 VDC volts wagon rabbit. 40 HP presto-light serious wound!!! I have 8 '12 volt MK jell packs! 100 amp hour, deep cycle. About 9kw, I would like to get to 40kw. How many of those would I need?
you need a BMS that can go with these - you need to test it to show how good these are - you also need to show some compelling use cases (like building a power wall or offgrid battery system). Otherwise it's hard for DIYers to figure out all these themselves.
do you entirely lack an imagination? He showed you how you can take a 10S pack and add a 3S or 4S chunk to make a "48V" pack that'll suit your inverter and you just stack these up in parallel until you get the size you need. These are ridiculously easy to DIY, probably some of the best cells out there due to their massive size and the cell holders. Almost as easy as 280/304Ah LiFePO4 prismatics cells. Looks like the bus bars on the ends make it stupid easy to wire the balance wires. You don't have to use these in a stationary energy storage system since they technically do offer the power for a vehicle so long as its nothing insane. Golf Cart, ATV,...I mean you could even potentially use these on a large bike if you aren't using a high voltage....36V seems manageable but 48V is much more common...you'd have range for DAYS. So for a cargo bike if you have the room to do a 12S or 13S pack you could potentially ride for 2 or 3 days before you even think about charging. So long as you're willing to tackle the liquid cooling you could definitely put these in a small EV and they are without a doubt some of the most energy dense cells you could get at this price. So many people make some janky packs with pouch cells because the cell holders aren't available (thanks big companies for forcing us to buy on a gray market that often doesn't include all the accessories because its just a matter of getting whatever we can get) and I think its moderately dangerous to DIY a way of connecting tabs and of course an ultrasonic welding machine is way out of the hobbyists price range. Getting a connection that doesn't have questionable resistance consistency means DIY'ing power pouch cells is just a real pain in the ass and you also want to do your best to imitate the cell compression the engineers designed for these things....and there's a million different sizes of pouches out there so you're not going to find holders meant for another model that fits. So TLDR; what do you need to power that these WOULDN'T work for?
im building a 1kw with 3 42v 10ah and alot of chinese components, to backup my pc UPS, cuz, losing work is worst thing. it was supposed to be cheep, like 150€ but im at 300, i think and still need to get a better step down, cuz my ups is 24, i need to feed 26. cuz i just learned baking up another battery, with lower voltage, will ignore the lower voltage backup untill the power from firts batter is over. it is very very tricky. only videos like this made me adventure into this, and i could have bought 2 agm bats and i was done. still, watching this im power hungry and wanna build more
I was super stoked when I saw LG, was about to put in an order for a couple 9s and a 10s, but then noticed they are not actually LG cells, but a copy. Now I'm second guessing. $100/kWh is great, but not for a no name Chinese cell
Nice score, trying to do the simple math on this, to work this into a 51v pack for a 48v system I would need 14 of these? Would mixing the Li-ion chemistry of these with LifePo4's cause an issue? I would assume not as the BMS's of each type of battery would be responsible for the charge? Love the vids!
BMS isn't responsible for charging. Your charger is. BMS is just last line of defense. You cannot mix the two chemistries at all. Totally different voltage curves and different voltages.
Wow, great video. I want to be a DIY solar battery builder. Will you make a video showing step by step how to make this battery? I would also be really interested in LifePO4 batteries to make 24v or 48v systems.
shipping abroad seem to not work again cause EU links do not really work cause batteryhookup ends in an error and the italian shop has nothing in stock that is comparable and those prices are ridiculous compared to your US prices.
What are people using to connect these together? Spot welding doesn't work does it? To those uninitiated, remember you MUST compress these cells, just as was done originally or they'll expand and self destruct.
I'm a newbie but I have been waiting for a 36volt battery for my 1960's golf cart... Will this work and if so how many would I need to fulfill a golf carts need ?? Thank you
I think what you are seeing is that people are starting to put a value on their time. Cheap doesn't work if I have to spend weeks of my time putting it together or waiting on parts from china. That is why the lifepo4 12v 100 are always sold out and the 36v and 18650 is always in stock. these will sell out fast.
Id love to have a 100 kwh of these, I already have about 18-20 kwh of cells similar to this in 7s groups, If I had the money I'd definitely buy some, I'd buy every month if I knew they would be more the next month, or if I could get some type of finance, I pay cash for everything, and cash Is funny right now, it's avoiding me!! 😙 But in a couple months I'd love to buy some, I need to power my off grid home, there is going to be two of us, and more power is going to be needed!
These pouch cells don't have the lifespan of LiFePo4. They have a liquid electrolyte that will eventually evaporate and degrade battery performance. Life expectancy for these is around 300 charge/discharge cycles, or around 18 months of life. At that point, you will see considerable degradation. LiFePo4 can last upwards of 5000 charge/discharge cycles so the added expense has them beating out lipos over the long haul for an off-grid, home power application. Not to mention the added safety. IMHO
you re right about turnkey theory but none in my place or even around 500 km range from me ever offered anything like it !!! so I tried ready option and paid 1 kilovat for 1200 euros ., i know i got some more safety but kidding me... i could have 6 to 7 kilovats with bms and inverter in those money there!!!!
i hope you intend on breaking the modules into 1s3p groupings to feed the supply that is sold out because $500+ is a bit much for 12 cells . i looked and 218 ah / 3 p makes 72ah. any more than 72ah would make a 12s too heavy for ebike use. i would buy 4 1s3p modules and re configure them to to 12s1p. why i want to do that too is it helps keep the shipping in check too where they can go by ground not require such high level of hazmat declaration. if why you are able to sell them so cheap is because you are drop shipping or pre selling them so you dont have to keep stock you may want to drop ship. you can ship via air but it has to be by cargo plane NOT passenger plane so if you have to ship from china or some other country you dont have to go by sea. if the modules are already in the united states and you are buying from another recycler like licycle or batteryhookup you could drop ship from licycle or batteryhookup to the customer. thereby you dont have to pay for storage thereby keeping the costs down. another way to keep costs down is to NOT take returns unless they are defective where they are dead on arrival or a fire happens where they burn down the carrier's vehicles and/or hubs. it may be possible for you to work with uber connect to ship too. you could subsidize the battery costs via cashing out your videos.
I have got some NMC pouch cells and after 1500 cycles they claim to retain 80% of their capacity. But I would imagine they would start running too hot after 1500 cycles due an increase of internal resistance making them unsuitable for high power applications with charging to 80% depth of discharge you can get 2500 cycles.
In Ukraine we have a lot blackouts. This "guys" help me out. I made from them a backup system 7s6p with a hybrid inverter. (In the instagram there are a few photos)
@@jasonbroom7147 I think you made a typo in your figures. you write "A single cell is 3.7v nominal, so a 7S pack is 24.9v nominal", that should be 25.9 nominal. at 24.9v for a 7s, it would be 3.55v per cell nominal, which is no good...
I agree. DIYers want a deal. I don't want to have as much in a project once I put a project together as i would buying a finished battery. Time is money. Should be selling at a typical markup, not what they think they're worth. Doing something DIY, I want to have half as much than I would buying a finished battery. I'm sure these were purchased at a hell of a price. Push that deal to us. Don't raise the price because they're wanted. Don't take this the wrong way. I love the videos and ideas.
@@jehugarcia Well this is just my two cents... 12, 24, 48 volt systems are the most common. So if I can't get individuals or a 7S configuration I guess I'll have to pass on this option. See several of your projects are 36 volts and in my opinion they're just not very common or readily available. Additionally I would like to see you make a project out of these packs similar to your recent 36 volt server rack. But this time in a 24 or 48 volt version with these packs that you are selling in this video. I hope this makes sense. Keep up the good work!
On your website it shows you have Valence Lithium Battery U27-12XP | 12V 138AH 1.766 kWh can you make a deal on 12 of them I need to make 2 - 72 Vold Becks for golf carts
Hey Jehu, how hard would it be to configure the module on single cells? Is it possible at all without breaking it? I need to build a 96s 1p pack for a EV and this batteries would give me a good 60Ah pack, let me know I'm very interesting to get a pre order if this is possible.
@@justinguerrera8322 it's for a Nissan Leaf which is a 96s pack, those loose LG cells Jehu mentioned are a pretty good deal, the only problem with those is that it needs to be build with a sort of case that keep it compressed, so the cells doesn't get expand when it gets charged at higher rates
They are not, I’m just not pre-selling any more for now, first batch is all sold and we will lost more once we get delivery of them, I wanted to see customer interest that’s why I pre sold them.
Jehu, any thoughts on my comment? If these were affected cells in a recall, I think customers deserve to know what they are getting. I know the community is DIY, and people are fully okay buying used, but these are unused and cheap for a reason.
Yeap but i don’t have an answer for you, there’s very little info on these and as I understand these are off the shelf modules used in many vehicles. If these do end up being recalled I will probably not continue to sell them.
@@jehugarcia Thank you, I appreciate the comment. I saw the singles opened up again and I put in an order for 14. Under $1k for 9kwh is worth the risk I suppose. Ive had good luck in the past with your batteries, and I hope it continues. Cheers
100,000 vehicles were recalled with these batteries due to a fire hazard. A manufacturing defect was discovered. may be to use at home is safe.. nobody knows. What you think about this?
I literally just watched your video while doing research for this battery. Australia right? Any concerns since you know where these came from? Would you stop charging at 80% like Hyundai recommended? Definitely keep these in an outdoor metal shed. Have you noticed any expansion? I would think the compression bars only come on the 9s and 10s packs so one could not build a single 14s battery since there is no 14s compression bars available?
Are we at the point where EV kits are getting close enough and affordable to do? Battery, cooling plate, charger, motor, controller, tranny adapter plate, etc. I'm ok with DIY but would rather have a kit that had all parts vs trying to find/research all the various pieces needed to assemble something functional. An "email for a quote" would be perfect for that and a customer could say "I've got a make/model/year with this ICE tranny and motor I'd like to convert to EV" and we'd get back a price with specs like HP, etc. Even a link to get this motor here, that adapter plate there, etc would work and then we'd buy your battery and BMS gear from you.
These cells had saved a lot of time and space compared to a 18650 build. 😄
Nice you can stack them.
True that!
What size bolts or such do you need?
Any pictures of how they interconnect? Trying to make sure I fabricate / buy bus bars and bolts ahead of time so I can assemble everything asap.
Love seeing all these cool cells you get in. Here in the UK everything is expensive or junk.
Long time no watch. Bad on me because your channel is full of amazing content. Good to see you healthy and still helping the world.
If you find a way to ship to Europe or the UK as a group buy setup maybe then that would help sell a lot of units, probably a 20ft containers worth at least.

It depends though how far tou push them. Many inverters aren't even close to EV power so manage the voltage and it should be good.

Yeah these are what the defective cells got replaced with. These are recent batches not the 2018 recall batch
I’d love to see more LFP.
but are these really LFP cells ? So far I am aware of LG Li Ion cells from the surplus production they had produced for Kia and Hyundai vehicles where the batteries had been burning and LG had to pay for the fully exchange at least inside the EU.

@@typxxilps these most certainly are li-ion. Jehu said he’s not sure what people want anymore. I’m saying I’d like to see him offer more lfp.
Can't wait to see these! High capacity with form factor.. makes me think all kinds of new products. Thinking an extremely compact chair with primary cells on TOP of drive system as well as the chair itself containing at least 50 percent of total capacity

These are pretty close to turn key,
if you supply bus bars and BMS (BMS pair?) that can boot into it… then people can buy it & piece it all together

Hi, if I get the pre-order cells will there be a guide or video to show us how to setup everything for a solar system or will we have to piece info ourselves from YT and google?
These are perfect for a rack setup, you should start making turn key rack battery. With these batteries

Can you revisit one of your old DIY UPS builds with updates for some of these newer batteries?
I'm curious as well, but they usually are laser welded to one another in each module.
I like these a lot. no project for them yet but i am thinking of vanlife and sailboats
You need a 48v variant on your sales chart.
I still watch your channel, even though im in Canada, Love this module. Maybe you need to think about an annual warehouse sale? Get some shelf space back, some cash.
I greatly appreciate your ideas. I am sure that there are times you may feel as you feel you can champion. Hang in there amigo!
48V would be nice to combine with a high quality home backup inverter

Should I use 8 of them for a 24V battery or better 7? Because of maximum voltage ...
is there a case that fits these? looking for something for offgrid use.
I was super stoked when I saw LG, was about to put in an order for a couple 9s and a 10s, but then noticed they are not actually LG cells, but a copy. Now I'm second guessing. $100/kWh is great, but not for a no name Chinese cell

Yes this is a 36v battery, but I know nothing of golf carts so your best bet is to research what specs your battery has, and compare it to this one

Yep. I’ve been researching this issue. I have a couple individual batteries myself.
I THINK PRESALE IS AN EXCELLENT BUSINESS PLAN. DO IT FOR EVERYTHING TO TAKE THE RISK OUT OF IT FOR YOU!!! Appreciate you Jehu!!!

i hope you intend on breaking the modules into 1s3p groupings to feed the supply that is sold out because $500+ is a bit much for 12 cells .
i looked and 218 ah / 3 p makes 72ah.
any more than 72ah would make a 12s too heavy for ebike use.
i would buy 4 1s3p modules and re configure them to to 12s1p.
why i want to do that too is it helps keep the shipping in check too where they can go by ground not require such high level of hazmat declaration.
if why you are able to sell them so cheap is because you are drop shipping or pre selling them so you dont have to keep stock you may want to drop ship.
you can ship via air but it has to be by cargo plane NOT passenger plane so if you have to ship from china or some other country you dont have to go by sea.
if the modules are already in the united states and you are buying from another recycler like licycle or batteryhookup you could drop ship from licycle or batteryhookup to the customer.
thereby you dont have to pay for storage thereby keeping the costs down.
another way to keep costs down is to NOT take returns unless they are defective where they are dead on arrival or a fire happens where they burn down the carrier's vehicles and/or hubs.
it may be possible for you to work with uber connect to ship too.
you could subsidize the battery costs via cashing out your videos.
What are the life cycle for these batteries?
I have got some NMC pouch cells and after 1500 cycles they claim to retain 80% of their capacity. But I would imagine they would start running too hot after 1500 cycles due an increase of internal resistance making them unsuitable for high power applications with charging to 80% depth of discharge you can get 2500 cycles.
Please share them for UE/EMEA too!
what kind of bms would go with this?
I'm looking to buy these the link doesn't work
More super cool videos.👍 WTG JAG!
Can you use it for a 12-volt car audio system
Can you offer in 14s? Only way now would be to order 10s and 4 x 1s.
Just buy 2x9s modules and a 10s module. Split the 10s into 2x5s modules and attach to the 9s modules. Done.
I think I want 4 off those love ❤
Its possible to order this bqttery?
off topic china announced 8 months ago of a sodium-ion battery whats ur thoughts
I have none, I only know what I have access to
In Ukraine we have a lot blackouts. This "guys" help me out.
I made from them a backup system 7s6p with a hybrid inverter. (In the instagram there are a few photos)
Is this battery too much voltage and,or amps for DIY Booster Battery for your Bluetti /Ecoflow/ iriver??
You can do 6s and you would have a hell of a booster pack (3.9kwh)
These are probably extra cells leftover from recall replacement stock
Talked to my supplier and these are definitely not the recall batch, They are the replacement packs for the defective cells
Keep it going
Are these good for sur ron battery builds?
can you make a 12v battery with these modules? What is the voltages?
@@jasonbroom7147 I think you made a typo in your figures. you write "A single cell is 3.7v nominal, so a 7S pack is 24.9v nominal", that should be 25.9 nominal. at 24.9v for a 7s, it would be 3.55v per cell nominal, which is no good...
buddy i do not mind making a battery pack,, but i need 48V and prefer lipo in my home,, not the nmc
What would be the best way for use in a golf cart 48V?
prob put 14 of the 1s3p modules in series and hook up a bms to it.
Your not selling because the price is to high for DIY, for a little more you can get something with free shipping and 10 year warranty LFP 48v.
I’m still selling 1M+ a year, what I meant is I don’t Necessarily know what will sell anymore
I agree. DIYers want a deal. I don't want to have as much in a project once I put a project together as i would buying a finished battery. Time is money. Should be selling at a typical markup, not what they think they're worth. Doing something DIY, I want to have half as much than I would buying a finished battery. I'm sure these were purchased at a hell of a price. Push that deal to us. Don't raise the price because they're wanted. Don't take this the wrong way. I love the videos and ideas.
Sold out. I'm a little too late. Maybe next time .
how many charge/discharge cycles on these? Can we buy just the enclosures?
Haven’t found data sheet with cycle life info yet. What enclosures?
The plastic housing, maybe enclosures is not the right word...
HOW MUCH DOES THE 9S WIEGH?
Will it be mandatory to have cooling for home use??
Nothing is mandatory, pretty sure you need to cool these on storage application
I wonder if we can reconfigure the cells to have a 72V60AH battery. 4.3KWh sounds like a very nice battery for a motorcycle.
@@jasonbroom7147 Might have to stick 3x 24v packs together then.
@@jasonbroom7147 It would definitely be a chonker. But if you design the chasis around it, it should be fine.
1S is already "out of stock". How is that on a presale?
We
Might split more 9s modules into singles. We just didn’t have any how much interest there would be on these, so we are playing by ear
@@jehugarcia Well this is just my two cents... 12, 24, 48 volt systems are the most common. So if I can't get individuals or a 7S configuration I guess I'll have to pass on this option. See several of your projects are 36 volts and in my opinion they're just not very common or readily available. Additionally I would like to see you make a project out of these packs similar to your recent 36 volt server rack. But this time in a 24 or 48 volt version with these packs that you are selling in this video. I hope this makes sense. Keep up the good work!
Do you still have them for sale still?
We are actually still waiting for part of the first batch, they didn’t send us everything we purchased so we are still waiting
Also, what is the remaining aH in the cells on average? I mean these are used. What capacity remains?
These are unused cells
On your website it shows you have Valence Lithium Battery U27-12XP | 12V 138AH 1.766 kWh can you make a deal on 12 of them I need to make 2 - 72 Vold Becks for golf carts
No i ran out of those, the link goes to one of my suppliers, Try to make a deal with them
Can you pleas test how fast is the charging and cappacity for home Bower wall?
Is there a webpage where i can order them?
Yes, click on the link
And a 24v variant.
I want 48v 9k but I am in Canada can you help me with shipping also need a good bms
Hey Jehu, how hard would it be to configure the module on single cells? Is it possible at all without breaking it? I need to build a 96s 1p pack for a EV and this batteries would give me a good 60Ah pack, let me know I'm very interesting to get a pre order if this is possible.
Not easily, look at the loose LG cells we have, that would be way easier
You wouldn't be happening to be building a pack for a Bolt by chance? Because that's what I would like to do.
@@justinguerrera8322 it's for a Nissan Leaf which is a 96s pack, those loose LG cells Jehu mentioned are a pretty good deal, the only problem with those is that it needs to be build with a sort of case that keep it compressed, so the cells doesn't get expand when it gets charged at higher rates
I want buy 14s3p 9kwh. How I can do this? Lithuania
I hope these are not part of the Chevy Bolt battery recalls.
If I had to guess these are unused modules to go into the Kona EV that were recalled, manufactured by SK innovation.
Interesting… video 6 weeks old for pre-sale on lots of them. Now they are sold out. And no easy way tp contact or ask questions.
It’s taking longer than expected to get these delivered to us, we are dealing with a big company with lots of beurocracy unfortunately

@@jehugarcia then they are not “sold out”
They are not, I’m just not pre-selling any more for now, first batch is all sold and we will lost more once we get delivery of them, I wanted to see customer interest that’s why I pre sold them.
@@jehugarcia understood. Seems like website could make situation more clear
Chevy Bolt EV cells?
Not the bolt but probably pretty similar
Dear jehu can it be sent to India
the problem is the price 100usd per KW is out of budget and shipping kills.
if it was 100 usd per KWh free ship then i would say it is priced right.
It’s nice to want to pay less, but these are selling fast so the market is supporting the price.
@@jehugarcia im glad i have found better prices and glad you have found a market
Do you have a shipping outside the United States I want to buy 14
Sorry USA only
Okay thanks keep going
Jehu, any thoughts on my comment? If these were affected cells in a recall, I think customers deserve to know what they are getting. I know the community is DIY, and people are fully okay buying used, but these are unused and cheap for a reason.
Yeap but i don’t have an answer for you, there’s very little info on these and as I understand these are off the shelf modules used in many vehicles. If these do end up being recalled I will probably not continue to sell them.
@@jehugarcia Thank you, I appreciate the comment. I saw the singles opened up again and I put in an order for 14. Under $1k for 9kwh is worth the risk I suppose. Ive had good luck in the past with your batteries, and I hope it continues. Cheers
Can the individual packs be parrelled or do the packs only connect in series.
Yes they can be paralleled, 2 of them for 1s6p 360AH or 1s9p 540AH and so on
@@jehugarcia perfect. 2x 10p + 1 module would be 21 modules to build a 7s with 3 modules in P
100,000 vehicles were recalled with these batteries due to a fire hazard. A manufacturing defect was discovered. may be to use at home is safe.. nobody knows. What you think about this?
Anybody find a ready to use chill plate for these?
L I K E 👍👍👍👍👍 💥 🤩 💥 🤩 💥 🤩💥🤩💥 💯💯
Are those Bolt batteries?
No
These are Chevy bolt battery's
Nope
Chevy uses LG cells.
Can I make a 3500 kw one?
Yes
@@jehugarcia what would that cost including shipping to Miami.
WHAT ABOUT A 20S MODULE?
It can be made
These are Hyundai KONA batteries;
i have 60kwh of these in lg chem
from a vehicle recall
I literally just watched your video while doing research for this battery. Australia right? Any concerns since you know where these came from? Would you stop charging at 80% like Hyundai recommended? Definitely keep these in an outdoor metal shed. Have you noticed any expansion? I would think the compression bars only come on the 9s and 10s packs so one could not build a single 14s battery since there is no 14s compression bars available?
Looks like the battery from a Smart Car. I had one.
Are we at the point where EV kits are getting close enough and affordable to do? Battery, cooling plate, charger, motor, controller, tranny adapter plate, etc. I'm ok with DIY but would rather have a kit that had all parts vs trying to find/research all the various pieces needed to assemble something functional. An "email for a quote" would be perfect for that and a customer could say "I've got a make/model/year with this ICE tranny and motor I'd like to convert to EV" and we'd get back a price with specs like HP, etc. Even a link to get this motor here, that adapter plate there, etc would work and then we'd buy your battery and BMS gear from you.
48v is what I want. Nobody uses 36v
You can build 14s with these
I’m in for 3kw
