Pro tip. The other end of that multi-color ribbon cable will have tiny bits of exposed wire on the end. Even when flush cut.
You want to avoid having the end touching anything.
Im impressed, was impressed before but this is what we were waiting to see. Start to finish build. Aeesome.
Thank you for all the information I have been watching your channel almost 3 years now. Every time I watch I begin to understand a little more about evs or better pack build ups. Its been 2years of me looking for the perfect bike to build I will eventually buy one and source most things from you or sites you reccomend. I'm glad I didn't jump in it right away because it seems tech is coming up faster than finding a Hayabusa in my area at the right price. I started collecting old laptop batteries but with all the information you give which I greatly appreciate is becoming much easier. Mostly I'll come out with a better build. I thank you brother and speak many blessings on you.
This channel gets better by the day, This type of project went from hard to easy REAL FAST!
Your heat sinking videos how and what can you tell me what you're using is it on an iPhone and adapter where can I get it thank you very much I saw you all the time whatever you need whatever I can do let us know thank you for showing us all the way it's very very appreciated

LOVE your channel love what your doing with recycling the battery's, so much that I just ordered 6 battery's for my vaping mod. thank you for the great way to save money, save the landfill, and support a small business. YOUR AWESOME
Welcome to the future. Good job, Jehu.
Nice build Jehu. I like this video. Good that you check the temps everywhere.
Great info as usual. Thanks for keeping us up to date
Straight forward and very informative. Thank you so much.
DIY Powerwall. Great idea! Keep up the great work!
This is a great video! I love it!
Thats batterie Art...just love it
Helpful video, keep them coming!
Really like this system you can replace any part of it if it goes bad nice job 👍
Nice and clean idea!
I think heat shrink over the standoffs between boards might be a good idea. That way if you drop a tool or something you will not get a dead short across the standoff terminals.
Ecospider5 agreed! Massive design oversight...
Clumsy people should wear helmets everyday, but to suggest everyone use them is extreme. Sounds like you are accident prone, take the needed precautions to stay safe.
@@jehugarcia that is too funny but even really careful people can sometimes slip up. :)
I like your idea to use multiple BMS systems. As they love to break... However running them at 50amps if one has broken.
Anyway I'm planning to use multiple BMS on the e-bike battery's I will build
Thanks for the great vids & ideas! One question I had was is that matching the cell voltage really that important? I believe those BMSs have balancing functions on their own and if it doesn't the user can balance it via one of those BattGO systems. I think the BMSs balance because on the last video when you were testing the BMSs overcharge protection, it was supposed to draw 0 but the reason it drew like 10w is probably because it was balance charging the other cells. I think this can make assembly and battery health monitoring much easier.
Anyways. I think these projects are great! Please keep it up the world needs more of this :)
Be better with battery internal resistance match
Really good video!! Best regards from Perú!!
I undertand so so.. I Will use traslator for your videos :(
Love you're work mate. I am from south Australia and we pay an average of 35 to 42 C per KWH. Stuff like this is life saving.
I'm in port Lincoln mate what part off this Australia you in
Nicko Blicko look into HBpowerwall channel, and AveRage Joe for better, more consistent, reliable good info. Pete’s a great guy too (for a QLD’er hehe)

Small world!
You can crimp the connector with a vice. Be gentle closing the vice and do not over tighten. When crimping a connector you feel a stiff resistance at first as the connector bites through the cable's plastic insulation. Then it becomes easy to finish the last 60% of the crimp. You do not need to give a final "tight" squeeze, it only damages the plastic.
Robert Harker Or even a piece of hardwood and hit it with a hammer if you are careful.
Anybody know the name of that crimping tool on amazon? I have had fairly bad luck with my vice, too slow. Or a link?
Jehu, you should install a 13 kW solar electric panel array on your roof, build two or three DIY powerwalls with these pcb’s, so all your home and electric vehicle charging needs will be met, even during blackout and to avoid expensive peak power rates during high demand times of day?!
Great job
Verry nice... thx jehu
Great vids, bought some cells. Was wondering in all the builds you do...any issues with discharging cells while continually charging with solar charged?
What I don't understand is why he hasn't incorporated heat management into the system (A fan to turn on to keep things cool If they get too warm… To maximize battery life)
Unscrew the chrome fan guards and get more air! No mod. is needed. Leave two screws in, keeps the fan attached, no need to take back cover off.
The chrome fan guard will have virtually no resistance / airflow impact.

Are you going to make the led Indicator
Pcb available?
This video, single handedly, will be responsible for the rising cost of reclaimed batteries
Just hmu I get used 18650 laptop modules for way cheaper than anything can offer.
It's like looking for old rusty coins on the beach when you can order pre-rolled never been circulated change from the comfort of your home. Reclaiming batteries should be like Folk Art it should understood but that's about all. No one wants old under/over cycled highly unpredictable cells everyone wants the new LG Panasonic Samsung cells. Why would you want recycle batteries when you can get 60+ Amp rated 21700/26650/3200P/32650 up to 10,000mah for $1-$13 each wholesale. Headway 10AH 100A cells are $15-$30 why are people dumpster diving for old batteries with a few dozen more cycles left in them... Maxwell 17v "SELF BALANCING" Super Capacitors modules which have over 1,000,000 cycles are $150 each from Mouser & Digikey and people loitering trash piles when it's trash for good reason seeing as It's trash compared to New(0 cycle) Lifepo4 batteries PCB balanced with Super Capacitors.
@@mindyabiznarc it sounds like a very small amount of money to you, but some people don't have that. I won't be dumpster diving, but I'm considering using batteryhookup.com for mine
@@mindyabiznarc A 10,00mah battery for $1😒 F**K off you troll.
What is the savings between used/new?
Great teacher :D
Thanks for the great video
Nice work
Great work! Are you planning on making a "21700" kit?
Great video
Power walls are OK but I wanna know how to make a ev or improve my hybrid.
What can I use to make a new battery pack? Do I use this or the battery pack method with the bus bars and individual fuses and bms in a plastic holder?
I love your channel, please is it possible to get this in 4s?
Very impressive 🙏🙏🙏👌👌👌
Nice one
When are we going to see a complete video on how to build the pack and charge the pack form solar using the BMS?
Amen. I’m not an electrical engineer I’d like to build one and install it using plugged solar panels. But also would like to not burn my house down so I need step by step instructions from start to finish
@@mrramz424 same here Mr. Ramz. Great video but should go step by step on how to set up everything to run. So dummies like myself don't burn down anything... Come on man teach us...........
Your product is great and i've had a blast building my modules and testing them. They work great!!! I would also like to see more about your suggested wiring connections to inverter and solar setup's. Maybe also some suggestions on inverter charge setup (float and bulk charge), low and disconnect voltages etc. Thank you very much for the channel and hoping to see some of these video's
Great kit. How much current can you push down the ribbon cables? I take each core can only handel a couple hundred millamps?
I use a vise to press ribbon connectors on.
Great video I like your videos let me ask you can I connect those Harbor Freight rechargeable drill batteries and make a powerwall out of that
You should be able to, as long as you make sure that all of the batteries are relatively similar capacity as far as mah and voltage are concerned.
Mr. Garcia! Could you make a video showing us how to charge these battery packs with solar panels? I am confused as to how to set up the parameters for the solar charger correctly. Thanks!
I second this, more importantly the voltage i have to input into the BMS module, will 24v do?
The BMS is doing balancing to each row of calls. To hook this up to a solar system all you need to do is follow a simple guide online and connect it to your charge controller. Connect battery to controller first then panels. Controller usually decides what battery voltage its at and should take it from there, if its a cheapo change its charge voltage cutoff and float for lithium standards and you guys should be golden.
Quick question: On the battery module, what kind of metal is used to contact the pos 18650 anode and cathode? I am asking because I have read these types of modules typically use a relatively highly resistive metal that may be problematic to larger applications.
Cool!!
Where can I get the state of charge board or is it in your kit?
Where did you bought your voltage and current meter? Can you send the link? Thank you!
Could you please provide the model number of the tool you used to read the infrared heat. Would it be a good idea to use a smaller wattage Grid tie inverter so as to draw power from the battery bank at a lower amp draw?
hi, thanks for the video, I already calculated if I want to build a 5kw powerwall, it seems the diy way is much more expensive than buying factory complete powerwall.
How is the VW coming along
Can you surface mount these holders on both sides of the boards by bending the through hole pins?
Hi
Great video, has there been any updates to the kit in the last two years?
How many Amp hours did you get out of that setup from your test with the inverter?
This content is simply amazing, I am excited for future optimizations to your battery system. You have convinced me that I can do this myself. :') Thank you
I’ve just come across your channel and I’m fascinated. I was thinking about a “portable” power pack unit that takes charge from a solar source and back up mains source, that outputs to a plug socket. I am in rented accommodation, so a grid tie would be too permanent and bulky, but a small unit that could say run living room entertainment system, couple lights, and adsl broadband box would shave a modest amount off my bill. How would this be achieved using your kit method say? (Btw uk.)
Hi,
do you have a purchase url for the led kit? 24:52
Do you have a purchase URL for the Monitor ? 26:04
Hi jehu, will you make the pcb files available? This way I would be able to modify and experiment and perhaps give some other usefull implementations for the boards.
How can i use same for nissan leaf old modules?
I'd like to see a 48 volt build that I could build for my cabin
Interesting 'stack.' The long Alodine stand-offs that are used as a 'buss' seems odd. Why? While Alodine is a 'protective' for aluminum, it's a chormate and remains HIGHLY resistant to electrical conduction. The threaded portions should be chemically 'de-plated,' if indeed that's a Alodine or Iridite coating.
when you remove black and red cable at the bottom???
How many cell and BMS boards do you need to assemble to end up with something like the Tesla PowerWall?
how do the temperature readings compare between soldered batteries, spot welded batteries and this design?
Hi, how much does each of the 52Ah unit weight.. Thinking about playing with these for work research for vehicle battery replacement application. We currently use a smart battery that keep failing on us, rated at 24V 110aH @ 40lbs
it seems i'm behind xD . the charge meter is cool! . the whole pcb is. tbh.. haha. just a shy 800 euro away from starting it :P
How do you monitor the BMS? A computer? or what is the interface and how can I get alerts if some value is outside something I set?
I'm using the IMAX B6 80W Clone to check / charge my batteries. The booklet included warns against charging batteries with a protection unit. Do the batteries you are using have these attached? I see the indention at the top.
Again, great video, I'm still in catch-up mode on all your videos but I do have a dumb question, the plug says AC GRID what's is it connected to?
My guess would be a wind generator.
Is the battery state of charge available now?
Can you use these PCB kits in combination with the SBMS units you spoke about in a previous video?
That is a great combo
nice！
how is the EU shipping running ? like to know ( im from belgium ) i like to start building one 5kw battery.
sweet
What about charging this pack? Let's say if I want to charge it overnight on the cheaper rate and use it during the day. Then what kind of charger you recommend?
The subject of a future video
@jehugarcia I am a landscaper here in southern California. Certain cities are forcing my trade to switch to battery powered equipment. I all for it except, the lithium Ion battery packs are extremely expensive. Anyway you can make a video and help us out?
the ambient noise of you moving things around on the desk is VERY loud, a solder mat of some form of dampening would make the audio portion as good as the video portion
Since the indicator show the level of a column and not the level of a board, If you have a dead cell in one of the boards, how do you know what board it is?
If two units are wired in parallel to an 80 amp mppt solar charger should a xt90 connector be used instead of xt60?
id just put a fan over that board in my design lol
how long it was running until fully discharge and at how much watts was the load.
What is the meter thats tracking amps, volts , and watts when he hooked the inverter up?
What's the deal with *internal resistance?* On the used cells with around 2700mAh, there seems to be a resistance difference between 14 and 112? - as seen around 5:00
What is the tune you use on your timelapses?
Hi, how would I use Repackr with the 2 sided build?
Well, here goes nothin'. I just finished population my first 25X. I need
to assemble it with the BMS. I'm using an Outback Flexmax 60 MPPT
charge controller and a 880 W solar PV array which has it's own SOC
ability. I may need to go back and check the balance but for now I just
want to get it working. I also have a Flexmax 80 and will eventually use
it with another 4 panel PV array, for a total of 1800W. The cells I'm
using are some pretested ones I just bought at the garage sale and a
bunch from those medical 3.7V UPS packs. The next 350 cells will be from
the scooter packs, for a total of 75X. Should be one heck of an
off-grid powerwall system. These will replace FLA batteries. Outback has
the program for Lithium chemistry but I still wan the extra protection
of the BMS'.
How much is the total cost of these pack and how many Wh it has? Nice video!
Wot ya mean ....u put battery in it ..be what ever you buy you legend 🤣🤣
Hi Jehu, excellent video as always. I see that all your boards are designed to build 24V systems probably because that is what electric vehicles are working with. I'm trying to build the batteries and system for a Motorhome and are debating if to build it in 24v that would require me to use a 24v to 12v transformer or go directly to 12V. So the question would be if you have any of those boards to build 12v systems? A motorhome system is normally designed to have 100 amp hours but I'm trying to design something for 400amp hours for when I'm boondocking.
Hope you can point me in the right direction.

What does the charging circuit look like for this setup?
Got it. Can I buy 1 Battery PCB kit. Before I go full speed
and buy 25 I want to have 1 to use for testing, etc.?
make a vedio for what capacity of charger to be used with battery pack.
just a quick question. How you will Charge that?
There is not a lot of info on these pcb systems..... Any info on the rainbow bms connector system ?
Also the 7 line battery indicator board..... Does this show voltage on each of the paralell connected bms lines and do the bms lines paralell connect the cell banks ? Or is the battery indicator combining the reading for one cell from each board ??
My main curiosity with this is the safety. How do I know that the batteries aren't going to explode or cause any issues due to over or under charging?
This is awesome, thank you!
Has Tesla ever reached out to you and told you to stop using the word "Powerwall"?
Tesla loves me
Hi , your battery pack design is great. My only question is about your balancing, as you check the balance between the serial connected batteries on each board if I understand your construction correct. But isn't it the balance between the parallel connected batteries that is the most important? So that the number one cell on every board should match, then all number two and so on...
Best regards, Niclas (from Sweden)
I s thinking the same thing. Seems like you would need balance across all, but that's probably a noob thought.
you rule!
