Swap JK or JBD contactor BMS for regular JBD bms

[Quattrohead]

I am trying to parallel multiple battery packs and read the data from all of them. I managed to grab five JBD BMS but cannot use either a JK or JBD with the contactor. Therefore I'm wondering if anyone has the opposite problem of me and would like to swap equivalent BMS. I am in central East Coast Florida.

Hi @Quattrohead , please share details of why you cannot use it?
