A fairly high capacity 18650 battery that can deliver a decent amount of current.

The two batteries matches nicely, the battery is fairly constant it capacity with different loads, but it gets warm at high currents and I damaged one of the batteries at 30A.

Thanks HJK. It seems that even at 200mA discharge, the claimed capacity of 3000mAh isn’t achieved. Aren’t these rewrapped, reputable cells that should have full capacity? Am I interpreting the first graph wrong? Thanks

My gratitude to those who are willing and able to help others (in whatever way you can)! Being human is more than just existing for yourself. Smile

All brands may show lower than rated capacity. Rated capacity is measured at a specific temperature, may be measured with a timed constant voltage charge (It may charge slightly more capacity into the cell) and it is measured down to the specified minimum voltage of the cell, where I always stops at 2.8V
