11 Battery Charging and Discharging Parameters 1. Voltage: Voltage is the electrical potential difference between the positive and negative terminals of a battery. It’s the driving force that pushes current through a circuit, and it’s one of the most fundamental parameters to understand. Nominal Voltage: This is the average voltage during discharge. For example, a lithium-ion battery typically has a nominal voltage of 3.7V. Fully Charged Voltage: When fully charged, the voltage reaches its peak. For a LiPo battery, this is usually 4.2V. Discharged Voltage: This is the minimum voltage before the battery is considered empty. For most LiPo batteries, this is around 3.0V. 2. Capacity , measured in milli ampere-hours (mAh), indicates how much energy a battery can store. Think of it as the size of the battery’s fuel tank. Theoretical Capacity: This is the total energy the battery can store under ideal conditions. Actual Capacity: In real-world scenarios, the usable capacity is often lowe...
