Description
BYD 4680 15Ah LiFePO4 Cylindrical Battery
SPECIAL ORDER ONLY – FOR TESTING ONLY – WE ARE UNSURE IF THIS
Standardized Design
- 4680 industry-standard size, enabling easy and streamlined pack assembly.
- Incorporates innovative Laser Cleaning technology and central-tabs design to reduce internal resistance for better performance.
High Safety Standards
- Successfully passed Fire Burning, Nail Penetration, and Over-Charging tests.
- During the Thermal Runaway Test, no severe chemical reactions such as fire or explosion occurred.
Superior Performance
- Cycle Life:
- 6,000 cycles at room temperature (25℃, 0.5C charge/discharge, 70% retention rate).
- 2,000 cycles at high temperature (45℃, 0.5C charge/discharge, 70% retention rate).
- Increased Power: 6 times the power of the 21700 battery, reducing costs, optimizing heat dissipation, production efficiency, and improving charging speed, energy density, and cycle performance.
- Non-Polar Ears Design: Full-polar ears design shortens electronic movement distance, reduces internal resistance, and significantly improves charging/discharging capabilities.
