This intelligent charger has four independent charging slots to charge any combination of Ni-MH, Ni-Cd, Li-ion, or LiFePO4 cells at the same time. The microprocessor monitors each battery and provides a safe and effective charge using precise Pulse Width Modulation (PWM) technology. A single Li-ion or LiFePO4 cell can also be fast charged at up to 2A. The high contrast LCD screen provides real-time battery monitoring, including charging current (A), charging capacity (mAh), voltage (V) and battery power (%). Features include alarm and error messages for bad batteries, reverse polarity protection, short circuit, over-charge, and over-temperature. Power comes from an available USB port or USB wall charger using the supplied USB Type-C power cable.
Suits a huge array of battery types:
3.6-3.7V Li-ion, 3.2V LiFePO4: 10340, 10440, 14500, 16340 (RCR23A), 17335, 17500, 17650, 17670, 18490, 18500, 18650, 20700, 21700, 22650, 26500, 26650 etc.
