Ansmann 21700 5000 mAh Battery with Integrated USB Type-C Charging Port

This Ansmann 21700 Li-Ion battery combines high capacity with integrated USB Type-C charging capability, making it ideal for modern high-demand devices such as tactical LED flashlights and headlamps. The cell features a built-in protection circuit board that safeguards against overcharge, over-discharge, short circuit, and deep discharge conditions. The integrated safety circuit extends the cell length by approximately 3–4 mm compared to unprotected standard 21700 cells, ensuring reliable long-term performance across thousands of charge cycles. Charging is straightforward via any standard USB Type-C cable connected to a computer, power bank, or 5 V USB adapter. Alternatively, the battery can be charged with dedicated lithium chargers. An LED indicator on the positive terminal provides real-time status feedback: red during charging, green when fully charged. The 21700 Li-Ion platform delivers approximately double the energy density of conventional NiMH batteries in identical form factors, with extremely low self-discharge rates and support for up to 2000 recharge cycles. Combined with low weight and an operating temperature range from −20 °C to +60 °C, this battery is equipped for intensive field use and demanding tactical applications. Specifications: Cell Type: 21700 Li-Ion | Nominal Voltage: 3.6 V | Capacity: 5000 mAh | Energy: 18 Wh | Operating Temperature: −20 to +60 °C
