I recently had the opportunity to try out this 3.7V 104080 Lithium Polymer ion Battery, and I must say, it’s been quite an experience! This rechargeable battery pack boasts a capacity of 4000mAh, making it perfect for a variety of devices such as MP3/MP4 players, Bluetooth wireless headsets, GPS devices, and more. Its size, at 10 x 40 x 80mm, is compact enough to fit comfortably in most devices.
The battery comes equipped with a JST 2.0mm Connector, ensuring a secure and reliable connection. However, it’s important to note that this battery should not be used for power-intensive devices like UAVs, electric toys, power tools, and the like. It’s designed primarily for low-current devices.
I’ve been using it with my smartwatch and Bluetooth speaker without any issues. The battery holds its charge quite well, and it’s always ready when I need it. The charging process is straightforward, although it does take a bit longer to reach the maximum charge voltage of 4.25V/2000mAh.
One thing that stood out for me was the customer service. Despite being an electronic product, there was a personal touch to the interaction when I had questions or concerns. The team responded promptly and addressed my queries within 24 hours.
Overall, this Lithium Polymer battery has been a reliable companion for my electronic devices. Its specifications make it suitable for various gadgets, and its compact size means less bulky packing. I highly recommend it for low-current device users who are looking for a dependable power source.
