It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.
Load power calculation is a fundamental concept in electrical engineering and is essential for understanding and managing electrical systems. By considering voltage, current, and power factor, you can determine how efficiently electrical energy is being converted into useful work.
Load (ampere or watt): Specify the load value, and select the load unit. For example, 100 Watt. Or 10 A. Use an average value if it is a cyclical load. Voltage (Vdc): Specify the battery voltage in volts DC, if the load type is watt. Required duration (hours): Specify the duration that the load must be supplied for.
The battery size calculator calculates the battery size in ampere-hour (Ah). Load (ampere or watt): Specify the load value, and select the load unit. For example, 100 Watt. Or 10 A. Use an average value if it is a cyclical load. Voltage (Vdc): Specify the battery voltage in volts DC, if the load type is watt.
These assumptions include: Battery capacity: The runtime calculation assumes that the battery has a specific capacity, usually expressed in ampere-hours (Ah), which represents the amount of energy the battery can store. Load: The calculation assumes a specific load that the battery will power. This not usually the case.
