This is a charger for 8-series LiFP battery packs, nominally 25.6V (8 x 3.2V), which charges at 29.2 volts (8 x 3.65V). The bulk charge current is 3000 mA. It is a multi-stage li-iron LiFePO4 recharger with universal AC input. Includes a slow start feature and a 4-segment fuel gauge. These are state-of-the-art battery chargers that can be used on-demand, or left permanently on the battery for maintenance. The slow-start function helps battery cycle life, especially with deeply discharged batteries. The charger is fully isolated from the mains, has universal AC input, and a removable AC cord. Will accurately charge lithium-iron-phosphate packs.
