Advantages vs 3.2V LiFePO4 Batteries
Higher Nominal Voltage
3.7V lithium polymer provides higher working voltage than 3.2V LiFePO4, delivering stronger power output and better performance in small electronics.
Higher Energy Density
Traditional 3.7V li-polymer offers higher capacity and energy density in the same dimensions, supporting longer runtime for compact devices.
Wider Application Compatibility
Matches the charging and discharging logic of most small smart devices, with better compatibility and simpler circuit design.
Mature Mass Production
Stable supply chain, lower cost, and higher consistency for mass production compared to LiFePO4 polymer in small-capacity sizes.
Better Low-Temperature Performance
Performs more stably in cold environments than most 3.2V LiFePO4 batteries, making it suitable for outdoor and portable devices.
