They are EVEs 304Ah but I buy them from Docan in China. Have bought plenty there before for home solar system. They are hooked up to JK BMS with a 2A active balanced which integrates with the Victron Cebro. To balance weight I put a Victron multiplus in the other side bed storage…

How do you charge that battery bank? And how long does it take?

Bruce
So I got 800w Solar on the roof which usually keeps it charged. I have a little generator I can top off if needed. Theoretically plugged in from 0-100% it takes about 9h.
When we travel distance a lot of times we drive in the evenings and work from the trailer during the day so even if the solar would not cover for the whole power consumed on not so nice days… the battery bank at least allows us to do this for a few days until we get to a destination where we check in at a campground…
For extended boondocking out west next year my next project are some diy foldable solar panels. To add another 400w or so…
