2-Power Hauptakku-Pack - Batería - 50 mAh (2P-5B11M90071)

Unlike generic button cells or bulky power banks, the 2-Power 2P-5B11M90071 delivers a compact 50 mAh lithium-ion solution engineered for micro-electronics, IoT sensors, and wearables where space and weight are critical. Its prismatic form factor and integrated protection circuit module (PCM) ensure safe, reliable operation in demanding embedded applications.

Highlights

• Ultra-compact prismatic Li-ion cell: only 25 x 12 x 4 mm and 5 g
• Integrated PCM guards against overcharge, over-discharge, and short circuits
• Nominal 3.7 V output with 0.185 Wh energy for low-power devices
• JST-PH 2-pin connector with 50 mm leads for easy integration
• 300–500 charge cycles with CE and RoHS certifications

In daily use

This battery is ideal for backup power in small electronic devices, sensor nodes, and portable gadgets. The built-in protection circuit allows safe charging at 0°C to 45°C and operation from -20°C to 60°C, making it suitable for both indoor and outdoor applications. The black casing blends discreetly into most device enclosures.
