I need help with wiring multiple 12v lithium batteries in parallel!
I have the following setup for my RV:
Magnum PT-100 Solar Cell Charge Controller
Xantrex freedom SW 2012 (100amp charge)
(8-11??)- 280watt solar panels
8- lifepoe lithium (k2B12VG27-3)100amp/hr batteries
RV QG 5500 generator with 20/30 dual breaker
I did not install this at the time and have been trying to learn since. I have Xantrex controller setup for (manually programed) lithium charging and use the gen to top of the batteries. However I can never seem to get them all fully charged with the wiring setup there currently in (all 8 in the same parallel string). Most of the info i see states that u should only put 2 lithium batteries in parallel. Does that mean i should do 4 sets of 2 lithium's in parallel, with all 4 positives from each set wired to one +lug to Xantrex and all 4 negatives from each set wired to the - lug to Xantrex? or all 8 separately? Anyone with experience in this?
