Just purchased a used Truck camper with a 100w solar /100AH battery set up. I bought Will Prowes' book and he said that you "CAN" use float charger to keep batteries charged while the unit is stored inside. He didn't however state if you need to make any special preps. Can you use the float charger, the one i have is a .75A Noco smart charger, as you normally would or do you need to disconnect anything ie. the panels or charge controller. Just dont want to fry anything.
