Batteries

Deep-cycle batteries for RV, van, marine and off-grid cabin systems — the house bank that keeps everything running when you are not plugged in. Two chemistries are stocked here: LiFePO4 lithium from Victron Energy, and sealed AGM from Sun Xtender. Lithium gives you far more usable capacity for its weight and a much longer service life; AGM costs less up front and works with simpler charging. Which one fits depends on your loads, how long you go between charges, and what is already charging the bank.
