Looks alright man!

Jokes on me… I’m glad I thoroughly check balance voltages before connecting. One of these little buggers got twisted in the base and I mis soldered. Easy fix if you check things first.

I would be more concerned with the soldering on these then the routing of the balance wires…

This is why I never paid these prices and started building my own…

You using an expensive ESD mat on top of your sacrificial work mat :rofl:

EDIT: oh I take it back, its just a fancy silicone mat.

I wouldn’t go as far as to say “fancy” by any means haha

What I was thinking is that A+ meant there was nothing you can possibly point out that is bad, basically flawless. Where there is ambiguity, I just tend to compare to the others I guess. IDK we will figure it out.

Got a lin- never mind I watched the video. I don’t have a battery pack like his, mines are lipos. Soldering the balance wires are easy money, just need to know where the charge port goes

Ok, its a DC port. Does it not matter where the wires go or it goes in a certain part?

Could I solder the positive to the battery harness main positive, add my fuse holder in between the negative wire to the BMS power?

You need to connect your charger to the balance port and determine which pin is which with a multimeter. That’s the only sure way of doing it.

Be careful, don’t lick the terminals while the charger is plugged in.
