2-Power pääakku - akku - 50 mAh (2P-5B10W51854)

For ultra-compact IoT devices, wearables, and custom electronics, the 2-Power 2P-5B10W51854 Main Battery Pack delivers a 50 mAh lithium polymer cell in a remarkably small footprint. Unlike bulkier cylindrical cells, this flat Li-Po pack integrates a protection circuit module (PCM) and a 2-pin JST-PH connector, making it ready for direct integration into space-constrained designs.

Highlights

• 50 mAh capacity at 3.7 V nominal (0.185 Wh)
• Integrated PCM for over-charge, over-discharge, and short-circuit protection
• Compact Li-Po format with 50 mm wire leads and JST-PH connector
• CE and RoHS certified for safety and environmental compliance
• Wide discharge temperature range from -20°C to 60°C

In daily use

This battery is built for low-power applications that demand reliability in a tiny package. With a maximum continuous discharge of 25 mA (0.5C), it suits sensors, beacons, miniature medical devices, and DIY electronics. The integrated PCM ensures safe operation, while the flexible wire leads simplify soldering or connector mating. Expect 300–500 charge cycles before capacity drops to 80%.
