Selling two Dragonfly Energy 100Ah 12V Lithium-Ion (LiFePO4) deep cycle batteries It is in excellent, like-new condition. This is the heated model (Model: DFTHO10012H) with the built-in "Heat Enable" feature. Standard lithium batteries cannot accept a charge in freezing temperatures, but the internal heating technology completely solves this issue. It is absolutely perfect for winter RV camping, van builds, or off-grid solar setups up in the Utah mountains.
