I have bought the 12s 40A BMS. (for use with 12 headway cells)
linergy-shop.de/product_info … 73—.html
It corresponts with the type 1 help diagram.
P+ (Discharge +)
P- (Discharge -)
B+ (Akku +)
B- (Akku -)
Ch- (Charge -)
Ch+ (Charge +)
Everything works perfect. But Charging does not work on the wire connected to CH- and CH+
Should I Try CH- AND B+ instead ?
Also B- did not have a xhr pin. So I hard wired this one.
