Tenpower 50ME 21700 Battery – 5000mAh

The Tenpower 50ME is a high-capacity 21700 rechargeable lithium-ion battery, designed for applications where extended runtime is more important than high power output. With a substantial 5000mAh capacity, it is an excellent choice for lower-power devices that require long periods of use between charges.

While the cell is rated for a maximum continuous discharge of 15A, a discharge current of up to 10A is recommended to achieve optimal performance and maximise available capacity. Each battery is supplied in a protective storage case for safe handling and transport.
