Hey guys, just got a 12s4p pack and I can’t go back to 10s, lol. It’s Samsung 30q cells and has a BMS on the outside of the pack. Charges fully within 4 hours with the 4a charger I’m including. Has a 7.5a fuse for safe charging. Has 10-15 cycles on it and have had it for about a month. Never fully drained it, always kept above 20%. Would like to get 280$ with the charger. Charges through a antispark and discharged through a regular xt90 Here’s pictures
The one on the left. Will include replacement fuses.
