I had 2 - 4D batteries, which were to heavy for me to handle. I installed 4 -24 group batteries in their place, hooking 2 together in each box. Thus 2 banks of 150 hrs each.
I have an old heart converter/charger that has died, I also have on genset for 110vt power.
When I read all about Xantrex systms, the truecharge 20+ seemed like the one. However they claim the "battery " has to be 100-150 APH to work. My question is will 2 -75 Aph be the same, or will it over cook the batteries.
