Introducing the D4 Digicharger from Nitecore, a sophisticated and efficient four-channel battery charger. The sleek and informative charger is compatible with a wide variety of battery sizes and chemistries. Capable of charging four batteries simultaneously, the D4 is capable of charging everything from Lithium-Ion, to LiFePO4, to NiMh, to NiCd chemistries, and automatically detects the battery type and status before entering automatic charge mode (CC, CV, dV/dt). The D4 Digicharger also automatically detects battery power status and selects the appropriate voltage and charge mode, with the exception of LiFePO4. You will have to manually select LiFePO4. Also, gone are the days where you have to sit around and wait for the battery to finish charging, as an automatic power-off function will cut off the current when charging is complete.
