Li-Ion 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours
Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
The Li-ion is stronger and has more run time.
So as the example below, it’s easy to calculation the WH of Sony np-f970 battery.
Chemistry: lithium ion
Capacity: 6600mAh
Voltage: 7.4V compatible with 7.2V
