2-power Main Battery Pack - Akku - 50 mAh (2P-TN70C)

Compact power for miniature electronics: the 2-Power 2P-TN70C is a single-cell lithium-polymer battery engineered for devices where space and weight are critical. With a 50 mAh capacity and integrated protection circuit, it delivers safe, stable energy for IoT sensors, wearables, and medical accessories that demand a slim, lightweight power source.

Highlights

• Ultra-compact Li-Po cell with 50 mAh capacity and 3.7 V nominal voltage
• Integrated overcharge, over-discharge, overcurrent, and short-circuit protection
• Lightweight PVC shrink wrap housing in black for easy integration
• Standard 2-pin connector with red/black polarity for simple wiring
• CE and RoHS certified; up to 300–500 charge cycles

In daily use

This battery is a drop-in power solution for low-drain applications. Its 0.5C charge and 1C discharge rates suit microcontrollers, wireless sensors, and wearable health monitors. The integrated protection board prevents damage from common misuse, while the flexible flat profile fits into tight enclosures. Self-discharge stays below 5% per month, so devices remain ready after storage.
