2 pieces of Samsung ICR21700-50E with protection electronics and USB-C charging function. Charging the 21700 battery P2150TC from Keeppower does not necessarily require a separate charger; it can also be charged through the integrated USB-C charging port with a USB-C charging cable. However, the option to charge this battery externally in a Li-ion battery charger remains available. The integrated PCB/BMS with USB-C allows for maximum discharge currents of 8A. It is also well-suited for the ACEBeam E70 LED flashlight.

With the IC protection/PCB that offers short circuit, overcharge, and deep discharge protection, the battery is suitable for all devices that do not have their own protection electronics, and it is perfectly protected against misuse, which nearly guarantees a safe and longer lifespan. The high capacity and flexibility make the 21700 battery (76.2 x 21.4 mm) P2150TC from Keeppower a great choice.

Charge your 21700 batteries in the charger or on the go at any USB-5V connection (USB power supply, smartphone charger, power bank, laptop, etc.), allowing you to stay flexible and always have a charging option at hand. The integrated LED at the positive terminal constantly informs you about the battery's charge level.

Please note the dimensions of the cell (76.2 x 21.4 mm) before purchasing. Due to the built-in electronics, the cell is not suitable for every application. Note: the height and diameter are slightly larger than a standard 21700 cell without PCB.
