3.8V high-voltage li-polymer provides higher discharge voltage, improving device responsiveness and performance.
Enables larger capacity in the same volume, extending working time without increasing battery size.
Supports higher charging efficiency while maintaining safety, suitable for high-end wearables, medical devices, and premium electronics.
Maintains stable voltage during discharge, reducing voltage drop and ensuring stable device operation.
Widely used in premium smart watches, Bluetooth earphones, GPS trackers, and industrial sensors that require high performance.
3.7V lithium polymer provides higher working voltage than 3.2V LiFePO4, delivering stronger power output and better performance in small electronics.
Traditional 3.7V li-polymer offers higher capacity and energy density in the same dimensions, supporting longer runtime for compact devices.
Matches the charging and discharging logic of most small smart devices, with better compatibility and simpler circuit design.
Stable supply chain, lower cost, and higher consistency for mass production compared to LiFePO4 polymer in small-capacity sizes.
Performs more stably in cold environments than most 3.2V LiFePO4 batteries, making it suitable for outdoor and portable devices.
