I'm building a new battery bank with 28 EVE 280Ah cells, and I'm wondering wether the following setup is valid. At 0.5C the battery pack can continuously handle about 400A, but in reality I will only use 200A (0.25C). Everything is designed on 400amps though. The system is 24V.
The Batrium Watchmon 4 will monitor and actively balance all 28 cells. The BMS will also control both Victron chargers, but as a fail safe it also can close the Gigavac contactor (rated 400A).
Is this setup valid, or am I missing something?

- Is it safe to use a common contactor for the parallel batteries?
- Should I add a MEGA fuse to limit the current to 400A (or just use 1C as max current = 840A)? Or add fuses on each of the 3 batteries to avoid high currents between the packs in case a cell short circuits?
- Do I need protection for inrush currents on the contactor and how to do this?
