5200mAh 26650 Li-Ion battery 70.3x26.5mm with integrated USB charging port. The 26650 P2665U battery can be charged via the integrated USB charging port or in a charger designed for Li-Ion batteries. The built-in electronics protect the battery from deep discharge, overheating, and short circuits. Please pay attention to the dimensions: approximately 70.3x26.5mm. Three charging options are available: via Micro-USB, charger, or in application. With IC protection/PCB featuring short circuit, overcharge, and deep discharge protection, this battery is suitable for all devices that do not have their own protective electronics, ensuring protection against misuse and guaranteeing a long lifespan. Keeppower P2652U with BMS/PCB and charging electronics. Charge your batteries in a charger or on the go at any USB 5V port (smartphone charger, power bank, laptop, etc.), allowing you to stay flexible and always have a charging option available. Please check the cell dimensions 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 26650 cell without PCB.
