100 W
I have to 72 volt lithium ion battery packs each with its own internal BMS. They are hooked in parallel. The rated cutoff is 56.9 volts. Today they cut off at 69 volts. I have ridden at 65 volts and still had juice left. Is it possible that one pack was low enough to cut off causing the entire system to stop even though 1 pack had enough juice to register at 69 volts? If this is so would it be better to fix some sort of switch to switch between the two batteries and run out one at a time? Any advice would be greatly appreciated
