Thanks again for all of your help. I am happy to report that i seem to have solved the problem, although i am also sorry to say that i seem to have waisted your time.
The problem was a bad connection at the busbar of the charge controller. I think what happened was that i forced the screw too much the first time i hooked the system up. Then, when i disassembled everything to change my setup to parallel instead of in series, what happened was that the wire of the battery somehow went under its prescribed hole in the busbar instead of into it. I noticed the bent busbar when i disassembled my charge controller to see if there was any bad wiring inside. I bent the busbar straight again with some pliers and everything seems to be working fine now. So as you said, the problem was a lose wire. Will even mentions the poor build quality of the rovers busbar as one of its major downsides in his review of it.
Completely my mistake, im sorry to have wasted your time.
