Built for High-Current Applications
The INR21700PL delivers up to 12C / 60A continuous discharge with an 80°C temperature cut-off. This makes it suitable for high-power 21700 battery packs that need strong current capability without sacrificing too much capacity.
Its rate discharge performance is solid. Compared with 1A discharge capacity, the cell is specified to retain:
- 10A: ≥97%
- 20A: ≥96%
- 30A: ≥95%
- 40A: ≥95%
- 50A: ≥90%
- 60A: ≥60%
For high-drain 21700 designs, pack-level thermal management and BMS cut-off settings are still essential.
Fast Charging and Low Resistance
The cell supports 3C / 15A fast charging to 4.2V with a 50mA cut-off at 25°C, with a maximum cell surface temperature of 50°C. Its internal resistance is ≤5mΩ, which helps reduce heat and improve current efficiency in high-rate packs.
Charging current should be reduced at low temperatures. Proper BMS settings and thermal design are required for safe fast charging.
Cycle Life and Temperature Performance
Cycle life depends on charge and discharge rates. The datasheet lists:
- 1000 cycles at 8A charge / 10A discharge, ≥80% of initial capacity
- 500 cycles at 8A charge / 40A discharge, ≥60% of initial capacity
- 300 cycles at 3C charge / 30A discharge, ≥60% of initial capacity
For low-temperature discharge at 40A, capacity retention versus 25°C is specified at ≥80% at -20°C, ≥90% at -10°C, and ≥95% at 0°C. At 45°C, the datasheet lists about 85%.
Storage recommendations are 1 month at -20 to 60°C, 3 months at -20 to 45°C, and 12 months at -20 to 25°C.
Safety and Mechanical Reliability
The specification includes mechanical and safety tests such as vibration, 1.2m drop, 13kN crush, overcharge, forced discharge, 130°C hot box, short circuit, 55°C short circuit, and thermal cycling. Acceptance criteria include no fire, no explosion, and no leakage where specified.
These tests support the cell’s use in protected battery packs, but final pack safety still depends on enclosure design, BMS protection, cell spacing, and thermal management.
Typical Applications
The INR21700PL-5000mAh is well suited for:
- High-drain power tools
- E-bikes and e-scooters
- Portable power stations
- Garden and outdoor power equipment
- Industrial battery packs
- UPS and backup power systems
