The Calb specs are Max. Charge Rate: 1C, Standard Charge Rate: 0.25C.
I can or do charge @100A MAX for the 400aH bank as a rule. But, now I am thinking that this may be too much for a 4p4s setup......
What I am trying to avoid is purchasing 4 separate BMS for reasons of simplicity, avoid component redundancy and cost. It would be nice if I the model you suggested was modular where up to 4 of the mini balance boards could be added to the main board.
Question regarding charging.....
For a 16 x 100aH cell bank (400aH @13.2V nom.), are there any concerns or differences with charging @100A if it is a 4p4s or 4s4p configuration?
What I'm scratching my head over is this....
I have a 4p4s setup with 16 100aH cells, which is essentially 4 400aH @3.2V 'batteries' in series that create the 400aH @12.8V bank.
In my mind, I see my 100A @12V nom. charger current inputting into one of the 400aH @3.2V batteries first, and this...
