Keeppower 21700 - 5000mAh, Li-Ion 3.6V - 3.7V - with USB-C input and output
Item number: 12091
Manufacturer: Keeppower
The ultimate rechargeable battery for anyone who needs power for their devices (torches, wildlife cameras, night vision devices, etc.) as well as an emergency power supply for smartphones, headsets and all other devices that have a USB input.
A combination of 21700 battery and power bank
To charge the 21700 battery P2150TC2 from Keeppower, a charger is not necessarily required, charging can also be done via the integrated USB-C socket. However, 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.
With IC protection/PCB with short-circuit, overcharge and deep discharge protection, the battery is suitable for all devices that do not have their own protection electronics and are perfectly protected against incorrect handling or use, which guarantees a long service life.
High capacity and flexibility speak in favour of the P2150TC2 from Keeppower
Charge your batteries in the charger or on the go at any USB 5V connection (smartphone power supply, power bank, laptop, etc.), so you remain flexible and always have a charging option to hand.
Integrated LEDs on the positive pole provide information about the charging status of the batteries.
Please note the dimensions of the cell before purchasing! Due to the built-in electronics, the cell is not suitable for every application!
The height and diameter are larger than a standard 21700 cell without PCB.

Safety instructions:
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.
Scope of delivery:
1 x 21700 Keeppower battery with USB C charging option.
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.
