21700 Li-Ion XTAR cell - 4900 mAh.
The 21700 Li-Ion cell from XTAR has protection against discharge, overcharge, overload and short circuit.
Safety features built into the 21700 cell
The lithium-ion cell is equipped with protection against discharge, overcharge, overload and short circuit . This is to prevent overcharging or overheating, which in some cases can lead to the explosion of the cells. Using a regular battery without protection can be problematic for users who have never had contact with this type of cell. Using unprotected batteries provides the same performance, but requires more care when charging and discharging.
How to properly charge an Xtar 21700 cell
When charging the Xtar battery, high-quality chargers with a charge cut-off at a voltage of no more than 4.2 V should be used. Avoid overcharging and discharging below 2.5 V to extend the life of the cell. The battery should not be discharged at currents higher than those specified in the specification, nor charged at currents higher than those specified in the specification. For safety reasons, do not use cells if they are damaged or have a dented casing. It is important to avoid contact with water or other liquids. In addition, the product should be protected from overheating.
