Molicel INR21700-P42A 4200mAh (Gray)

Official specifications:

Rated typical capacity: 4200mAh
Rated minimum capacity: 4000mAh
Nominal voltage: 3.6V
Standard charge current: 4.2A
Maximum charge current: 8.4A
End of charge voltage: 4.20V +/-0.05V
Continuous discharge current: 45A (Cycle life is reduced at high rates)
End of discharge voltage: 2.5V
Typical impedance: <15mOhm AC 1kHz
Cycle life: 500 cycles at 4.2A charge and 10A discharge for 80%
Operating temperature: Charging: -20°C ~ 60°C, Discharging: -40°C ~ 60°C
Storage temperature: <35°C, recommended <35°C for long term.

This is a 21700 high current cell with good capacity.

The two cells match just about perfect and capacity do not really change with load.

I forgot the temperature sensor with the first battery.

Conclusion

This is good high current cells.

Notes and links

The batteries was supplied by N-Power Energy for review.
