OK I am looking to get batteries. found some 1100 cc 950cca 6v industrial tractor batteries for $50 each or 1050cc 750 cca 12v marine for $75
What is better the 6v or 12v and can you mix batteries like four 6v and two 12v running a 24 volt system
Does anyone no of a good cheap mppt charge controller for a 100 amp 12/24 volt system.
At the moment I have one of the ebay blue fake mppt controllers. I bought 8 old panels and he gave me the controller.
I am just getting started.
