Product description
XTAR SC2 is a 3-stage fast charger for 3.6 (3.7) volt Li-ion batteries. Suitable several different cell sizes: 14500, 14650, 16340, 17500.17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 25500 and 26650. The charger is very safe and specially designed for Li-Ion cells that do not have their own protection circuit. It also works with Li-Ion cells that have a built-in protection circuit.
The charger has two charging channels where each channel is controlled by a microprocessor. With two separate charging channels, each battery is charged individually according to its own conditions. No risk of overcharging or damaging any cell. This means you can safely charge two cells with different states of charge (SoC) or two completely different sizes or two different cell types at the same time. Blue LED indication shows the charging progress of each channel.
Controlled charging limits harmful wear and tear, ensuring that optimal cell performance can be maintained for a long time, even after many charging cycles.
Operation of 3-stage charging:
- Step 1 - Temperature controlled charging (TC)
- Step 2 - Constant current charging (CC)
- Step 3 - Final charge is with constant voltage 4.2V (CV)
Thanks to the 3-step charging method, fully discharged battery cells can be brought back to life. The charger has built-in protection against overcharging, short circuit, overheating and incorrect polarization of battery cells. The charger comes with a USB-A to micro-USB cable. Supplied without USB charger and without battery cells.
