Li-Ion battery 21700 5000 mAh with USB type C charging socket, Ansmann

Easy charging

The battery can be charged with a standard USB type C charging cable. A PC, a power bank or a USB power supply (5V) can be used as power supply. Alternatively, a lithium charger can be used.

Perfectly protected with a safety circuit

The integrated safety board protects the cells against overload, short circuit and deep discharge, so the rechargeable battery is protected against incorrect usage, which guarantees a longer lifetime.

Higher energy

Compared to conventional NiMH-batteries, the Li-Ion technology provides approximately double the energy density for the same size.

Low weight, low self-discharge and high cycle stability

The ANSMANN 21700 Li-Ion battery is extremely long lasting and can be recharged up to 2000 times even under tough operating conditions. With a very low self-discharge the battery keeps its energy for a long time, even when not used. The power to weight ratio is much better than other battery technologies (eg. NiCD/NiMH/PB), with Lithium being much lighter.  

Versatile applications

The high quality Lithium-Ion battery from ANSMANN is ideal for use in modern devices like LED torches, headlights, e-cigarettes, laser pens, etc. With its high capacity of 5000 mAh this is perfect for use in high power devices. Also, this battery can be used in a wide range of temperatures from -20°C to +60°C.

Information:

Because of the integrated safety board the battery is longer in size compared to the unprotected 21700 Li-Ion batteries. It s approximately 3-4mm longer.
