To convert the mWh into mAh use the following conversion. You will need to know the battery’s voltage to complete the conversion.
First convert the mWh (mega watt hours) into Wh (watt hours):
mWh / 1000
50810mWh / 1000 = 50.81Wh
Next Multiply the Wh and voltage to find the Ah (amp hours):
Wh * Volts
50.81Wh * 11.1v = 4.577Ah
Last step to find the mAh (milli-amp hours) by multiplying the Ah (amp hours) with 1000:
Ah * 1000
4.577 * 1000 = 4577mAh
