I am upgrading the battery in my RV to one built from 8 280 ah EVE cells. The rest of my system consists of a Victron multiplus 3000, mppt 100/50 SCC, BMV702 battery monitor, and Venus GX controller and 6 100w 12v solar panels. Its a 12 volt system. I think I've narrowed down the battery configuration and BMS to two options. Option 1 would use an single Electrodacus SBMS0 with the EVE cells configured as 2p4s. I would get rid of the victron venus GX and the SBMS0 would be able to turn the multiplus and mppt SCC on or off and I'd connect it to a victron battery protect to be able to disconnect the other 12v loads. Option 2 would use 2 JBD150a 4s bms and 2 4s batteries in parallel and would keep all my existing victron equipment as is. Option 1 only requires one bms and it directly controls the inverter/charger and scc, but uses paralleled cells within a battery. It might cost a little more up front but if I sell my Venus GX that would offset the added costs. Option 2 lets the victron venus gx control the charging with the JBD bmss acting as a failsafe and monitors every individual cell, but there are two batteries in parallel that might get out of balance over time. I'm interested in opinions on which is the better approach? There is one other confounding factor to consider, my existing battery is a 300 ah with internal bms. My plan was to remove it from the system. But If I wanted to include it that would steer me to option 2 with three batteries in parallel each with there own bms. Am I missing something to consider?
