Cycle life: 500 cycles to 75% at 23°C or 70% at 45°C (Charge=0.3C, Discharge=1C)
This is a high capacity cell in the new 21700 format.
Nice tracking discharge curves with fairly constant capacity, but the cell cannot handle above 10A without heat problems, this is acceptable with a maximum rating of 9.6A
I only discharge the cell to 2.8V, not the rated 2.5V and get a bit less than full capacity.
Battery gets to hot and i stop the discharge.
Conclusion
This is highest capacity 21700 cell at the current time (Jan 2018) and it looks very good, but it is not designed for high current discharges or fast charging.
Wondering whether the 48G would be okay to use for a pulsed, low duty cycle (5 sec. on, 30+ sec. off), 45-50W max. application with a 3.3V cutoff voltage.
Max. discharge current: 9600mA (Not for cycle life)
Max. pulse discharge current: 30A for 10sec, 25A for 30sec, 18A for 60sec
It looks good enough (I would expect double current needs four times the cool down time, i.e. 25% duty cycle at 2x9.6A)
But is would not guess on cycle life.
