Voltage Comparison: 3.7V vs 3.8V Batteries
3.7V Lithium Battery
Nominal discharge platform voltage is 3.7V, full charge voltage typically 4.2V, discharge cutoff voltage generally 3.0V.
3.8V Lithium Battery
Nominal discharge platform voltage is 3.8V, with some models reaching full charge voltage of 4.35V. Discharge cutoff voltage mostly set at 3.0V or slightly higher.
Energy Density
3.8V batteries typically use advanced cathode materials, allowing them to store more energy in the same volume or weight, resulting in higher energy density.
Cost & Safety
3.8V batteries are more expensive due to complex materials and processes. 3.7V batteries are technologically mature with lower costs and easier safety assurance.

Advantages of 3.7V Li-Polymer vs 3.2V LiFePO4 (LFP) Li-Polymer Batteries

Higher nominal voltage3.7V 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
