Advantages of 3.7V Li-Polymer vs 3.2V LiFePO4 (LFP) Li-Polymer 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 in same size: Traditional 3.7V li-polymer offers higher capacity and energy density in the same dimensions, supporting longer runtime for compact devices.
- Wider application in consumer electronics: Matches the charging and discharging logic of most small smart devices, with better compatibility and simpler circuit design.
- More 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 discharge performance: Performs more stably in cold environments than most 3.2V LiFePO4 batteries, making it suitable for outdoor and portable devices.
Applications
- Consumer Electronics: Bluetooth speakers, headphones, smart bracelets, GPS trackers, portable medical devices
- Smart Home: Smart door locks, sensors, cameras, remote controls
- Electric Toys/Small Appliances: Electric toothbrushes, shavers, robot vacuums, handheld fans
Quality Assurance
- A-Grade Battery Cells: High-quality materials, sufficient capacity, long battery life, safe and non-explosive
- High-Performance Protection Board: Stable voltage output, prevents overcharging, over-discharging, and short circuit
- International Standard Lead Wire: High-quality wire with strong conductivity, supports high-probability discharge
- Wide Nickel Tabs: Excellent thermal and electrical conductivity, reduces heat generation, ensures stable current output
