To convert watt-hours (Wh) to milliampere-hours (mAh), you need to know the voltage (V) of the battery. The formula is:
mAh = Wh × 1000 ÷ V
For example, if you know the battery voltage is 5V, you can use this formula to calculate:
mAh = 100 Wh × 1000 ÷ 5 V = 20000 mAh
So, if the battery voltage is 5V, 100 watt-hours would be equivalent to 20,000 milliampere-hours.
If you have a different voltage value, simply substitute it into the formula to get the accurate result. Please provide the battery voltage for a more precise calculation.
