This question may have been answered (potentially many) times before but I'm struggling as a noob. I have two separate 4S battery packs (8 cells in total) in a 12V system. Each one will be equipped with its own Overkill 120A 4S BMS(es?). I have a typical off-grid, camper van DC load and a 2000W inverter. If each other the packs are connected to two 300A fuses is that okay? Will the two 120A BMS units be enough to cover the load?
Bonus question: How would I connect these to the Victron Lynx Distributor battery in side? I have a Master Disconnect Switch and Battery Monitor shunt that I would prefer to just have one positive and negative wire. Should I use bus bars rated for 300A? If that's the case, would I even need to have two fuses or could I fuse the entire bank (pack #1 and pack #2 combined at the bus bars) "after" the bus bar, on the side towards the Victron? (I'll attach a schematic.)
