The UM4 automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging LiFePO4 batteries. Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the UM2’s four microcomputer-controlled charging slots then monitors and charges the battery independently. Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current while an intelligent automatic power-off function terminates current when charging is complete. The Nitecore UM4: The world’s most advanced fully-automatic digital charger. It’s as simple as insert, detect and charge.
