Battery charger Li-Ion 1A for 2x 18650

RND Power, 3-stage charger for 3.6 (3.7) volt Li-ion batteries. Compatible with multiple cell sizes: 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 25500, and 26650. The charger is highly safe and specifically designed for Li-ion cells without a built-in protection circuit. Also works with Li-ion cells that have an integrated protection circuit. The charger features two charging channels that are individually controlled by a microprocessor. Red LED indicates charging. Completed charging is indicated by a green LED. Because the charging process is controlled, harmful wear is limited, helping to maintain optimal cell performance over time, even after many charge cycles. Charging current: 0.5A per cell.

3-stage charging function:

• Stage 1 – Temperature-controlled charging (TC)
• Stage 2 – Constant current charging (CC)
• Stage 3 – Final charging with constant voltage 4.2V (CV)

Thanks to the 3-stage charging process, fully discharged battery cells can be revived. The charger includes built-in protection against overcharging, short circuit, reverse polarity, and faulty batteries. Supplied with a micro-USB to USB-A cable. Supplied without USB power adapter and without battery cells.
