UltraFire BRC26650 7300mAh (Gray)
- Capacity: 7300mAh
- Voltage: 3.7V
- Chemistry: Li-ion
- Recharge: up to 1000 cycles
This cell is specified with record capacity, but the measurements does not confirm this.
The real capacity is about 2500mAh and the two cells do not track very well when current is above 3A.
The cell is sold with wrong specifications, the performance is very bad and the wrapper lies about protection.
I will call this a bad cell.
