4 x EagleTac 3100 mah 18650 batteries + Nitecore D4 Digicharger + Car Charger Adapter + Going Gear LED Keychain Light

Charger: The Nitecore D4 is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The D4 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 D4'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 and time while an intelligent automatic power-off function terminates current when charging is complete. The Nitecore D4: The world's most advanced fully-automatic digital charger. It's as simple as insert, detect and charge. Battery: These second generation 18650 cells offer the highest available energy storage capacity, especially under heavy loading condition. During discharge, our 18650 3100mah maintains high voltage and high capacity output for better product performance.
