Im gonna have to read up on that. Im assuming that its a charging unit only. I am using the atwoods as converters so i would have to add that unit to my electrical "system" i am not sure if i can use the 3 bank system as my batteries are tied together in parallel and not easily accessable. I think i could use one bank for the agms and one for the cab bats, but if the cab selinoid sees 13.6 it will connect them together. Then i would add one more disco to the system and complicate things a little more. Sooooo many ways to do this I would just like it to be simple and reliable.
