Keeppower 21700 15A 4000mAh 3.6V - 3.7V Li-Ion Battery PCB Protected P2140R
Item number: 12075
Manufacturer: Keeppower
Due to the use of a high-current cell from Samsung, the P2140R battery offers higher voltage levels at high loads than nonhigh-current batteries. Applications such as torches or model making benefit from the voltage level. Lamps shine brighter, electric drives get more voltage even under load.
The 21700 battery from Keeppower has an output of 15A in continuous load.
Equipped with Seiko (Made in Japan). Protection/PCB with short circuit, overcharge and deep discharge protection as well as overcurrent up to 30A, the Keeppower battery is suitable for almost all applications.
Recommended use: torches, diving lamps, video lamps, model making, industry and all applications where the 74.5 mm length and 21.4 mm thick cell fits and is suitable according to the specifications.
Please note the dimensions of the cell before buying! 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-cigarettes.

Notes:
A special charger is required for charging lithium ion batteries, which 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 the number of charging cycles (possibly up to double). Only lithium ion chargers may be used for charging. However, the 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 small 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 at the municipal collection points or in the [usually green] containers provided by retailers.
