Dear electric vehicle enthousiasts,
A couple of days ago I decided to build a new cell-package for my Bionx 48v battery.
Once finished the bms started behaving wierd and the battery does not charge or power the bike anymore.
Once I first connected the charger I heard a rapid series of beeps (about 10) and then the charge port started flashing red.
When I now connect te charger I hear one beep and the charge port lights up red once and than nothing.
The charger continues to give a green light.
When connected to the bike sometimes the display turns on and other times it shows the message 'protect' and then turns itself off.
When the display stays on the battery indicator is 3 bars and the lights will work.
When I refurbished the battery I did resolder the temperature resistors, maybe this influenced something?
I checked the balance wires and main voltage, but everything seems to check out. Battery at 48v all the individual groups at around 3,72v.
The BMS does work, as it turns on, beeps and the charge port gives light.
Maybe someone has had a similar kind of problem or can help me out?
All help is greatly appreciated.
