hell
honestly not the worst thing I ever saw.
Itâs not completely terrible from a functionality perspective, but thereâs something uniquely fucking weird about it, probably the colors and my hatred for e-tape in general

donât forget the speaker wire
soldering is real neat though.
I respect the builderâŚyou gotta have nerves of steel to build and then USE a battery like this.

Or just be completely unaware of the potential safety issuesâŚa far too common occurrence IMO.

Anyone have some 20mm by 0.2mm nickel? Only need 400ish mm
Ive got 25x0.15
I still have like half a kilo of that too 
I can cut some 25mm down I guess, I just donât want to

Anyone ever checked how out of balance your cells are in the end of a deep discharge? This is the first board I have with a BMS that lets me check it, but seems too much off
Pack made of VTC6, 10S5P, unfortunately the cells didnât all arrive with the same voltage, some were at 3.8 v and some at 3.6 v, I should have taken the time to test each one for capacity and resistance
The sad part is that this is the only place I can get cells here, nobody ships and no other seller of high capacity cells, itâs that or nothing
Only thing I can do maybe is increase my cut off voltages a bit, that group 1 is what worries me most
Do you own a lipo charger that can balance? This large of a difference will take ages to balance out with a BMS. But you could bring them all up a bit then balance charge each group to 3.7 or whatever setting the lipo balance charger will allow. Iâve done this plenty of times.
I have, but they were perfectly balanced at the start, Iâm letting them charge, looks like they are getting closer again
But that sucks, to have to open everything and replace a P group, specially if the vendor doesnât replace it for free
Hm. The cells seem a bit suspect in that case⌠Can you balance and charge fully, then stop multiple times next ride for a few mins and get screenshots of the spread as they drain? See if it widens constantly or just dives off at the end.

Thatâs a good idea, will do, and I can also do with my adjustable charger, this is charging to 35ish V, will let it go to 38 next
Better but not great

Iâd say wait a bit, I had a p-group like that too, but it eventually evened out.

Is that black stuff potting compound?
Is it alright practice to make fully potted waterproof packs?
Nah itâs just black hot glue, we like to use it
