I'm impressed by the know-how that goes into making a battery. This video definitely proved to me that I'd be better off buying a ready-to-use battery rather than burning my house down.
Here's a tip, you can solder to your nickel strips and then spot weld them onto the batteries. That way you can not worry about heat. It does change your order of operations though, but just something to consider because cold solder joints can lead to problems
I just drilled through the positive and negative nickel strips/bus-bars and fixed a ring connector via a nut and stubby bolt. Then epoxy resin to keep it in place. Seems to work o.k
Interesting video dude. The right tools make for light work. ;) I didn't have a decent soldering iron, so i instead used a crimper and spade connectors to connect any 12awg wires together. Combined with the plastic heat shrink tubing (with adhesive) seemed a decent fix. Also in the ethos of utilizing as little heat on the cells as possible, i decided to improvise the main power lines onto the negative and positive bus bars, by drilling holes through the nickel strip then using ring connectors via nuts and bolts to fasten them together. After tightening them right up, i then epoxy resined over the fixing, for added stability/security. (vibrations would have a habit of loosening nuts over time i reckon) Way i figure it is if upwards of 500w of power is persistently flowing through a system, you wanna make damned sure that the fixing ent gonna crumble away. I reckon those solder joints on the main power lines could be a weakest link. Having solder in 3 places adds redundancy for sure, but i speculate that a hard fixing point is the way forwards. Meh i'm no professional electrical engineer though tbf ;)
VERY EDUCATIONAL......THANK YOUUUUUUU I AM AN AVID FAN OF EBIKE ESCOOTER CAN I ASK YOU A QUESTION, I NOTICED THAT YOU DIDN'T PUT FUSE IN THE CHARGING PORT, I ASKED THIS QUESTION BECAUSE I MISTAKENLY SHORT CIRCUITED THE CHARGING TERMINAL AND THE RESULT THE CHARGER STAYS GREEN WHICH SUPPOSED TO BE RED AND WILL ONLY GREEN WHEN IT IS FULLY CHARGED. CAN YOU GIVE AN INSIGHT TO THIS PROBLEM PLEASE
Most likely you'll just need to replace the charge port. Try charging from the discharge side (provided you have common port BMS aka 2 wire BMS that allows charging and discharging from same wire) Hope this helps !
Hey Tom, thank you for the comment! We are actually just using a black hot glue that can be found easily on Amazon. I've attached a link here; tinyurl.com/yc2dt5d3 Seems to work very well for our purpose. Best regards Myles
Great video I learned alot and I definitely want to build my own battery packs Only other comment is that you could've explained in a bit more detail why you ran the BMS wires the way you did and why. Thanks for the video Definitely want to take the course
first u should tell the capacity of each cell . if they are 2.6 Ah u can take 48v 10.6 AH 13S 4p , 52 cells but i did one for myself 48v 20AH with 52 cells but they are 21700 5 Ah each .
you state you do not need to do the positives as no current, can i ask how you worked that out, current flows from negative to positives as amps are not used in a circuit but are returned, i have never seen like this before from any other battery builder.
@@ElectricBikeLaboratory It's not my call. I'm trying to find a battery cell source that's less than $6 each. At $6 a piece, it would cost $468 in 18650 cells to make a 20ah battery. And over $550 total cost.
@@ecocentrichomestead6783 I ordered from a Dutch company called NKON. Imported here to U.K worked out about £3.50 a cell or so. Samsung 50e's - 21700. Decent cells.
Does the p stand for the group.4 pos 4 neg in each group on each side. Looks like I have seven groups on each side. That would make this a 14 s 4 p . Can someone confirm that. Not making it trying to fix it. 52 volt 20 amp hour
@@ElectricBikeLaboratory And all the leads need to be connected in order from - to + going down The Daly BMS lead . Or do the only ones that need to be in order are the positive and negative. If that is the case and they need to be in order I probably should number them before I put this BMS on.
Wow, love it, what a great project, thank you, Subscribed. Wondering if one can swap batteries from another bike battery to another bike ? Which Batteries are like what you said please? you missed an important part 😂 young man, also where to get that kit or what is its Exact name, as one I saw was $895
Haha yes , you can have 2 bases one on each bike and use the battery interchangeably. We're working on getting together more DIY kits but check out our site we do sell many of the cases and affordably priced cells "AEB 18650" www.affordableebikes.ca

FOLLOW UP TO THE QUESTION WHAT HAPPENED WHEN THE BOTTLED BATTERY IS NOT CHARGING AND I AM PRETTY SURE THE CHARGER IS WORKING GOOD COZ THE CHARGER IS WORKING TO OTHER EBIKE AND SCOOTER

what is the difference between black hotglue and transparent? i everywhere see black on youtube but wat is the difference?
What a good video that was.
You guys put out some fantastic content. Thank you!

Just a wild guess but
Have you done this before

How true that battery case can build 36v 50ah? i found it from Ali express, i wanted to buy one for my ebike
Question about the ribbon of balance wires: can't you route them without crossover? It doesn't matter which wire goes to which tab, right?
I get it now, black wire #1 is most negative, #2 2nd most negative ... order matters.
first u should tell the capacity of each cell . if they are 2.6 Ah u can take 48v 10.6 AH 13S 4p , 52 cells but i did one for myself 48v 20AH with 52 cells but they are 21700 5 Ah each .

Top quality!

Not really sure what you're asking here, we hook up the positives. Battery would not work otherwise?
About the tapes you are using... What would be the width of the Kapton and fish tape you would recommend to buy?
We like to keep 25mm / 50mm / 75mm / 100mm on hand
For fish paper we keep 65mm and 70mm on hand so they are the perfect width for the cells
What good is it to make a video on how to build a battery when the price of battery cells makes it too expensive for most people to both with?

How long does it take you in real time?
Building the pack around 2 hours but testing it is a lot longer if you factor in time to charge / discharge etc

Black Hot melt adhesive, and low temp hot melt adhesive (clear)
