I'm redoing the system in my 40' fifth wheel. I first installed the solar & batteries in 2015 using Fullriver 6v AGM x4 & 640w with a Xantrex pro 2000w PSW I'm updating to LFP and a 3000w inverter charger. The batteries are 8x REPT 280Ah from Exliporc and I sourced two JBD BMS units through...

Not sure if this is the right place to put this post or not. I decided to make my own bus bars and terminal posts as anything that looked reasonable was shipping from outside of Canada when I looked on Amazon. The posts use 1/4" bolts that press in from the back. They are printed using PLA and...

I'm building two 12v banks using 280ah cells in a 4s setup each with a JBD BMS. The BMS is longer than the batteries if I use the bus bars and put them face to face (right side of pic) and clamp as normal. If I put them in pairs and put a clamping rod in the center then the pack suits the BMS...

Just finished building my 2nd battery with the JBD BMS. Is there a way for the Xiaoxiang app to connect to more than one BMS? It just randomly picks the first one it finds and it takes a few tries of killing the app to get to the other and there's no way to know which I'm on without looking for...

I'm changing out my 6 yr old AGM batteries (fifth wheel trailer) for Lithium and this means that my onboard DC charger likely won't be able to properly charge the batteries as it has no profile for Lithium. The system is currently 640w solar into a Rover 40A MPPT to 4x Fullriver AGM and I have...

I searched but didn't find what I was looking for but maybe I'm not searching using the right words. I have two newly built 4s packs using 280Ah cells. They each have a JBD 150A BMS on them. I top balanced all the cells to 3.65 until the current draw was negligible. I have one of the packs...
