Looks like just one layer. And with series connections like that, one layer is plenty.

Personally, i would have located each solder point directly in the gaps between the cells, but I’m just nitpicking.

This pack can deffinetly pull 180 amps for a few seconds, but I don’t recomend maxing any cell like that. Rralisticly this is a 120 amp continues battery easily. 14awg x3 for series connections

Reason I have them closer together is because I want to route balance leads straight through the middle. I guess I could have still separated the series connections to be in between each cell

I appriciate the vote of confidence. Yeah I decided to switch to soldered series connections, as much as possible and only using smart bms. I’ve had 2 packs come back last weeks, both had folded nickel series connections that gave way to flex. Thankfully with the smart bms it was easy to see where the problem was right away. Had to rebuild both packs. Decided no more folding nickel! Atleast as much as possible lol.

I’ve also noticed that the places where the folded nickel gave way, was on 30qs possitive terminal…the terminal is, a bit concave after an insulator ring is glued on, and there is alot of stress on the welds. Other packs I have built with folded nickel series connections are still going strong…for now lol :sweat_smile:

The bms came with short balance wires and the connector is all full of somesort of silicone, would be an absolute pita to try and determinate it, so I spliced
