Do my chassis batt and house batts need a trickle charge to stay viable?
Would a monthly top up work just as well?
How deep should I let them drop before charging?
I have a 3 panel 45W total solar panel and controller.
Can I just connect all batteries 12V+6V+6V leaving the first positive and last negative open for the controller connections. I can use 1 or 3 panels.
So.... pant pant, how many panels should I use as a trickle charger to keep my batts alive but not boil them
