I have 2 12 volt batteries consisting of 4 eve 280 ah cells and a jbd bms in parallel and a victron multiplus charger. My cells seem to be behaving well and are very close in voltage. Balancing kicks in at 3.4 volts but cells are typically plus or minus 0.01 v. But at the very end of the bulk...

Pictured is the system in my travel trailer with my newly built batteries barely visible though the center opening (8 eve 280 AH cells configured as two 12 V batteries), 2 JBD 150 A BMS, and some other Victron equipment. I was testing every thing out and when drawing 200+ amps the battery side...

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...

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...

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've been commenting in some other threads but think its time to start my own thread on this. I have a Victron multiplus 3000, victron mppt scc, victron battery monitor, and victron venus GX device currently powered by a Lithionics 330 ah lithium battery in my travel trailer. I am planning on...

I need to purchase 2 JBD 4S 12v 120a BMS with bluetooth and UART usb com. Anyone have a suggestions where to purchase? Appears they are in stock at Overkill Solar but if I want to try and get them cheaper from China any suggestions? Has anyone used IC GOGOGO store on AliExpress ...

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...

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...
