You are spot on, another thing to consider the (3)-31's "should" only be discharged down to 60% which would give you 150 a/hrs of usable energy. While (2) GC2's can be discharged down to 40% conservatively which would give you 138 a/hrs. I would take 12 a/hrs less power for batteries that will charge faster via solar & last twice as long personally..... Agree??
