We just got back from a boondocking week, living on one 100ah LiFEPo4…it is a game changer (even though I hate that phrase)…turns the trailer into an iPhone…I estimate the two batteries I purchased, during the summer (low furnace use) would allow the trailer to go 4 days without charging. Battery at 20%? 80%? 47%? Doesn’t matter…lights are bright, TV/Sat is available, slides move snappy.
We have a 150 watt portable cell that we use to top off the battery or other portable stuff (CPAP battery) and use the Genset to do the bulk recharging…overnight drainage takes about an hour to bring back up to full.
SUCH a much better experience than the first year with the 12 lead acid and the second year with the two 6v golf cart batteries.
