I am in the planning stages for building a battery to replace the the 300 ah lithium battery in my travel trailer with something about twice that big. I'm considering using 270-320 3.2v cells arranged in two 4S batteries with their own BMS put in parrallel. I was planning on using two of the JBD/Overkill solar 12 V 4S 120 a bms. I know the alternative is to go 24 v with an 8S bms but I think I want to stay at 12 V because thats what my trailer is. Need to be able to draw up to 200-240 amps at 12 V. So does that design sound like the right option? I am curently following discussions on the forum about sourcing the cells. I have a Victron solar charger and Multipluss 3000 inverter charger in my trailer. Thanks--Frank
