Description

The EEMB 3.7V 1100mAh Li-Poly battery pack delivers steady power for small radios, Bluetooth speakers and other portable devices that use a JST connector. Its compact size (34.5 x 51 x 6.3 mm) fits tight housings while providing enough capacity for hours of playback. Built with PCM protection, the pack safeguards against over-charge, over-discharge, over-current and short-circuit conditions, extending cycle life and preventing leaks. You can trust the battery to stay safe even in demanding environments. Each unit weighs only about 22 g, keeping your gadget lightweight. The 1100 mAh typical capacity (minimum 1000 mAh) offers reliable run-time, and the 3.7 V nominal voltage matches the requirements of most small audio and radio modules. Important: verify that the connector polarity matches your device before purchase. Mismatched polarity can cause a short and damage equipment, because this battery is not universal. Choose EEMB for an affordable, high-performance rechargeable solution that combines safety, durability and consistent power output. Enjoy longer listening sessions and reliable operation with a battery that holds its charge over many recharge cycles.

Key Features

PCM protection monitors the cell and automatically stops charging or discharging when voltage, current or temperature exceed safe limits, guarding against over-charge, over-discharge, over-current and short-circuit events.

Typical 1100 mAh capacity (minimum 1000 mAh) delivers several hours of continuous playback for radios and Bluetooth speakers, reducing the need for frequent recharges.

Measuring just 34.5 mm x 51 mm x 6.3 mm and weighing about 22 g, the pack slips easily into cramped device enclosures without adding noticeable weight, making it ideal for portable use.

No leaking construction and long cycle life give you dependable power over many charge-discharge cycles, so the battery stays reliable even after months of regular use.

Check the JST connector polarity before buying; using a battery with opposite polarity can cause a short circuit and damage your radio or speaker, because this model is not universal.
