2-Power hoofaccupack - accu - 50 mAh (2P-5B10W51826)

Compact, reliable, and built to keep small electronics running, the 2-Power 2P-5B10W51826 is a 50 mAh lithium-ion battery pack that delivers steady 3.7 V power in a space-saving single-cell design. Unlike generic coin cells or bulky multi-cell packs, this unit offers a true rechargeable solution with integrated protection against overcharge, over-discharge, and short circuits—ideal for IoT sensors, wearables, and backup applications where every millimetre counts.

Highlights

• 50 mAh capacity with 3.7 V nominal voltage for consistent low-power output
• Lithium Cobalt Oxide (LiCoO2) chemistry for high energy density and stable discharge
• Integrated protection circuit guards against overcharge, over-discharge, and short circuit
• Compact 1S configuration with 2-pin JST-PH style connector for easy integration
• CE and RoHS compliant, with a wide operating temperature range from -20°C to 60°C (discharge)

In daily use

Whether you're prototyping a wearable device, powering a remote sensor node, or replacing a worn-out cell in a handheld gadget, this battery pack provides dependable performance. The 0.185 Wh energy rating supports low-current draws up to 50 mA continuous, while the 0.5C charge rate (25 mA) allows safe recharging in under three hours. The flexible operating temperature range ensures functionality in both cold storage and warm indoor environments, and the integrated protection means you can design without adding external safety circuitry.
