Why This New 21700 Cell Is Worth Your Attention
Overseas buyers often face the same problems when sourcing 21700 cells:
- Inflated capacity claims
- Short cycle life and high warranty risk
- High internal resistance and heat build-up
- Unstable supply and long lead times
- Weak low-temperature performance
- BMS mismatch and pack design issues
- Incomplete product documentation
- Pressure to reduce material costs
The BAK N21700CX-65E is designed to address these pain points with clear, testable specifications and stable bulk supply from Becell.

What Makes the BAK N21700CX-65E a Strong Choice?
Real Capacity, Not Just a Label
Rated capacity is 6350mAh and typical capacity is 6500mAh, measured under standard charge and discharge at 25°C. This gives buyers a clear baseline for pack design and testing.
Long Cycle Life
At 25°C, the cell retains ≥80% of its original discharge capacity after 501 cycles. That means lower warranty risk and better long-term value for battery pack makers.
Low Internal Resistance
With internal resistance ≤8mΩ, the cell runs cooler under high-current operation. This helps reduce voltage sag and supports stable BMS performance.
Strong Rate Discharge Performance
Relative capacity at different discharge rates:
- 1C: 100%
- 2C: ≥95%
- 3C: ≥90%
This makes it suitable for applications that need both capacity and reasonable power.
Good High and Low Temperature Performance
Relative discharge capacity:
- 25°C: 100%
- -20°C: ≥80%
- -10°C: ≥82%
- 0°C: ≥85%
- 45°C: ≥90%
- 60°C: ≥95%
This is important for buyers serving markets with cold winters or hot climates.
Safety and Environmental Testing
Safety tests are based on GB31241 and UL1642 test methods, including short circuit, overcharge, forced discharge, low pressure, temperature cycling, vibration, shock, drop, crush, impact, hot oven, and combustion injection. The cell also meets BAK’s hazardous substance management standard or customer-specific requirements. Please confirm the certificates required for your market with our sales team.
