Hi all good morning. I've noticed that balancing current varies tremendously from BMS to BMS. I'm still working on finalizing my design for my battery build which will be somewhere between 64 and 128 LifePo4 cells....I still haven't decided as yet but seriously considering starting with 64 now and adding another 64 later. Is there a general rule of thumb for balancing current based on battery capacity (Ah)? I'm leaning towards using a BMS with an integrated active balancer. I'm seeing varying options from 1A to 5A but I am not sure where the 1A balancing current BMS should be used vs a 5A balancing BMS? I would imagine the 5A would be used for bigger capacity batteries but what exactly does bigger capacity mean in the context of an active balancing current for 1A, 2A and 5A? I've seen 10A balancers as well but those seem to be standalone dedicated balancers.
Appreciate the feedback and thanks in advance.
