XTAR 21700-HP 25A (Ampere) *5000mAh 3.6V - 3.7V Li-Ion battery electronically protected.
Item number: 100644
Manufacturer: Xtar
While the protection electronics (**BMS) ensure maximum safety, the battery provides a powerful and reliable power supply with an impressive maximum continuous discharge current of 25A and a capacity of 5000mAh.
The built-in industrial cell was developed for applications such as heavy-duty drones, racing, industry, mobile energy, electromobility, LEDs, etc. With integrated protective electronics, it is particularly suitable for torches, diving lamps, underwater lighting and laser pointers.
**PCB / BMS protected 21700 Li-ion battery with 25A (Ampere) discharge current.
The high discharge current of 25A is protected by a gold-plated protection circuit (**PCB), which protects the battery against overvoltage, undervoltage, short circuit and reverse polarity at high currents. An explosion-proof valve completes the maximum safety.
Please note the dimensions of the cell before purchasing! Due to the built-in electronics, the cell is not suitable for every application!
Height and diameter are larger than a standard 21700 cell without PCB. Not suitable for e-cig.

Safety instructions:
Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by qualified persons.
Incorrect handling or short circuits can lead to fire or explosion.
Further properties:
Lithium-ion batteries are thermally stable and are not subject to a memory effect.
They work on the basis of lithium and are characterised by a high energy density.
* The specified capacity of a battery indicates the amount of energy it can store under ideal laboratory conditions. This value is measured at a constant temperature and under defined conditions in order to create a reliable reference for the performance of the battery.
**A PCB (Printed Circuit Board) is the printed circuit board on which the circuit is located.
**A battery management system(BMS) or simply battery management is a measure, but usually an electronic circuit, which is used to monitor, control and protect batteries.

Notes:
Charging lithium-ion batteries requires a special charger that charges the batteries according to a special charging procedure. (CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.1 volts, as this significantly increases the service life or number of charging cycles (possibly up to double). Only lithium-ion chargers may be used for charging. However, cheap chargers sometimes have the disadvantage that they do not switch off safely at the end of the charging process, but continue to charge the batteries with a low charging current, which can be dangerous.
Furthermore, rechargeable batteries and batteries do not belong in household waste! Please dispose of them as prescribed by law in the municipal collection centres or in the [usually green] containers provided for this purpose by retailers.
