You try changing the BMS to static balance and letting it run overnight to fully balance out the pack? That’s what I had to do with one of my groups.

I did not try a static charge. I ordered 4 more cells and plan to replace the Pgroup. @kook these cells are brand new, less than 5 cycles.

Yeah I need to clean them again. Just did some digging for fireworks tonight. Received the charger at the same time

Static isn’t charge, it’s just actively balancing until it satisfies your maximum voltage difference setting.

Im pretty sure the cells in that pgroup have a higher internal resistance. They won’t go above 4.16v

measure (that’s what she said) right at the tip… a 4mm plug will be about 3.6mm

12S4P Molicel P42A ready for spot welding. This will be a flat pack in TB40 deck. However, my AliExpress nickel order is stuck somewhere. Anybody got 0.2x25 or 0.2x30 nickel to sell in the US? I can pick up in Bay Area. @Skyart @KfromtheBay @ZachTetra? Also, comments about pack construction so far are highly appreciated! Thanks!
