Ned a new BMS for hailong battery

[lcarron]

Hi

I inverted the charging polarity on the charger and of course damaged the BMS of my hailong battery. I can still charge the battery but the battery is always on even the switch is off. Do you know where i can buy a new Bms?

What's the problem with it being on all the time? Don't you have a switch on the controller?
