You decide to use a battery labeled "205 mAh 1S" with a total voltage of 3.7 V. What is the overall energy capacity of the battery?

Answer: 0.7585Wh

Explanation:

Battery capacity = 205 mAH

Nominal Voltage (V) = 3.7

The overall energy capacity of the battery is measured in watt-hour. Which is the product of the battery capacity in Ampere-hour (AH) and the nominal voltage of the battery in volt (V)

205mAH = 205/1000 = 0.205AH

Therefore, energy capacity:

0.205AH * 3.7 V = 0.7585Wh

This gives us the amount of energy stored in the battery per hour.

Therefore, a battery with nominal voltage of 3.7V and current capacity of 205mAH has a maximum energy capacity of 0.8585Wh.
