Re: BMS alternative cell level charge protection only.

For discharge, I plug a cheap lighted volt meter into the battery charge port and if/when that goes OFF, I then know about a potential cell voltage problem even though power is not disrupted going to the bike. It shouldn’t be too hard to rig slightly more elaborate warning lights/buzzer that simply...

Re: BMS alternative cell level charge protection only.

I have already one of those (white ones) on my actuall pack. use it for charge only and works so far. But what you say about price is totally true, just doubt about size now and maybe to built splitable packs to carry them on flights.
