Thanks for that. I did see the Daly Pack Parallel Module. I have not been able to get comfortable with the BMS units where the charge and discharge current is passed through and regulated by it. I've settled on 1 string of cells at 304 Ah for now. I bought a REC 2Q BMS that just controls a contactor to interrupt charging/discharging if parameters get out of bounds. I like this way because it's easy to bypass the contactor in a pinch. REC do have the ability to parallel strings. I think (not sure) it would be 2 BMS plus a master module. I finally just had to get off the fence and do something, so I took the easy way out and went with a single string.

Does the Daly BMS allow for 200A current - I'm guessing your motors are 48v/10kW?
I have twins in my cat but a single 1,000AH/48v pack with Winston cells - 16s. Much simpler than two packs.
what model Daly handles parallel connections safely
