Apparently I have burned-up two JBD AP21S01 6S-to-21S BMS systems. In both cases, it happened when programming parameters using the XiaoXiang APP (For example, I was adjusting the 20/40/60/80% points). I got smoke from overheating the first few channels of the sensing/controlling circuits by burning-out some of the 510 ohm and 1K resistors. The conformal coating is brown now.
A.) I have no idea why this consistently kills the BMS--anyone understand this? and,
B.) are there more-recent model suggestions of a rock-solid BMS for a 48V, 16S over-100 Amp application today?
I have 16 new and perfectly top-balanced 304 AHr LiFePO4 EVE cells. The BMS ran beautifully. All cells within 30 mV. I ran the pack up and down just fine. The fully charged state was reading 18% capacity so I re-programmed the percentage SOC parameters and poof...
Suggestions would be really appreciated.... Tom.
