Results Will Vary
Motor efficiency, spring strength, gear ratio, wiring, MOSFET, temperature and battery condition can all affect actual runtime.
Estimate your airsoft battery runtime, usable capacity and approximate number of shots before recharging.
A higher value represents a less efficient or higher-load setup.
SPM means average shots fired per minute of active play.
Avoid planning around 100% of the battery’s stated capacity. An 80–90% allowance is more conservative.
Motor efficiency, spring strength, gear ratio, wiring, MOSFET, temperature and battery condition can all affect actual runtime.
Use the correct charger and follow the battery manufacturer’s charging, storage and minimum-voltage instructions.
A second charged battery is recommended for long game days, high-rate builds and colder operating conditions.
This calculator provides planning estimates only. It does not measure the actual electrical efficiency, current demand or condition of your airsoft gun or battery.
