    BMS failed, need help selecting new one

    Hi,
    My BMS failed in a 1.5 yo battery. The BMS that is currently in the battery does not have a balance connection, only a P and C connection. I don’t see any replacement BMS with a C connection and no B connection. Any suggestions on how to connect a new one or where to get a new one to match my connections? Is the balance connection important and can I add in a balance connection on my existing battery.
    Battery is 14S 52V 15AH

    Also, failure mode, bike dies under heavy load. 5 PAS etc. If I disconnect and reconnect the BMS it comes back and works fine until I push it hard again.
