Keeppower 21700 - 5000mAh, Li-Ion 3.7V - 3.6V - PCB protected with USB-C charging option P2150TC
Item number: 12076
Manufacturer: Keeppower
A charger is not necessarily required to charge the 21700 P2150TC battery from Keeppower; it can also be charged via the integrated USB-C socket. The option of charging the battery in a charger for Li-Ion batteries is still available.
The integrated PCB/BMS with USB-C allows discharge currents of 8A.
IC-Protection/PCB with short-circuit, overcharge and deep discharge protection makes the battery suitable for all devices that do not have their own protection electronics and is perfectly protected against incorrect handling, which guarantees a long service life.
High capacity and flexibility speak for the P2150TC from Keeppower
Charge your batteries in the charger or on the go at any USB-5V port, (smartphone power supply, powerbank, laptop etc.), so you stay flexible and always have a charging option at hand.
Integrated LEDs on the positive pole inform you about the charging status of the batteries.
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.

Safety instructions:
Please note that lithium cells may only be used by competent persons.
Incorrect handling or short-circuiting can lead to fire or explosion.
Further properties:
Lithium-ion batteries are thermally stable and are not subject to memory effect.
They work on the basis of lithium and are characterised by a high energy density.
Scope of delivery:
1 x 21700 Keeppower battery with USB charging option.
When ordered in pairs (two pieces), the batteries are delivered with a battery storage box and USB-A to USB-C cable.
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.
