2-power Main Battery Pack - Batterie - 50 mAh (2P-5B10W51818)

For ultra-compact electronics where every millimetre and milliamp count, the 2-Power 2P-5B10W51818 delivers a dependable 50 mAh lithium-polymer cell in a slim pouch form factor. Unlike bulky cylindrical batteries, this flat pack slips into wearables, IoT sensors, and custom embedded projects without adding unnecessary weight or volume. Its built-in protection circuit guards against overcharge, over-discharge, and short circuits, so your prototype or production device stays safe across hundreds of charge cycles.

Highlights

• 50 mAh capacity at 3.7 V nominal – ideal for low-power sensors and microcontrollers
• Lithium polymer (Li-Po) pouch cell with bare-wire termination for flexible integration
• Integrated protection circuit (overcharge, over-discharge, short circuit)
• Rechargeable with 300–500 cycles to 80% capacity
• CE and RoHS certified, 12-month warranty

In daily use

This battery is a practical choice for makers and engineers who need a compact power source that can be soldered or connected directly to a PCB. The bare-wire leads allow you to choose your own connector, while the pouch format conforms to tight enclosures. It performs reliably within a charging range of 0°C to 45°C and a discharging range of -20°C to 60°C, making it suitable for both indoor and outdoor sensor nodes. Storage between -20°C and 45°C ensures the cell remains stable when not in use. With a single cell and an energy rating of 0.185 Wh, it provides just enough power for intermittent data logging, BLE beacons, or small wearable accessories.
