How would we calculate how much energy a particular battery can store, and how would we size this up against the devices we will need it to power? In this post we will explain the use of Ampere-hours (Ah) as the common measure of capacity, evaluate the use of Kilowatt-hours (kWh) as an alternative and more flexible measure, and determine how to calculate Kilowatt-hours (kWh) using Ampere-hours (Ah) and Voltage (V)....
