    Wire gauge for JBD 150a bms

    I am building 2 12v 280ah 4s batteries each with a jbd 150a bms that will be connected in parallel. Each bms has two screw terminals for the B- and two for the C- connections. I am not counting on using the full capacity of the bms but seems reasonable to design the wire for 150a since that's...

    Is paralleling batteries just wrong?

    I'm in a conversation on the Electrodacus forum in which I asked opinions on a configuration with an Electrodacus SBMS0 bms and a 2p4s battery pack versus two 4s batteries each with there own JBD 150a bms, both based on 8 280ah EVE cells. Electrodacus replied that paralleling lithium batteries...

    Electrodacus SBMS0 with 2p4s or 2 JBD with 4s2p

    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...

I am planning on...

    Can't decide between these configurations and bms

    I'm want to build a battery pack for my travel trailer with 8 280-310 ah cells. Can't decide whether to configure the cells as 2P4S wirh a single Delgreen/Daly 4S 250A BMS or as 4S2P with 2 JBD/Overkill 4S 120A BMS's. Cost is not that different and I've seen people argue both ways on these...
