runtime calculator.
Enter your setup. Get an estimated runtime and a battery-size target for the hours you want to fish.
Roughly 24 hours and 56 minutes of power.
For a 10-hour session with your selected settings.
Estimates assume a relatively steady load. Real runtime changes with temperature, battery age, discharge rate, voltage cutoff, wiring, and screen settings. Don't use as a guarantee.
No magic numbers.
Just transparent math.
Battery amp-hours × nominal volts estimates stored energy. We adjust for your usable-capacity assumption, conditions, and system losses, then divide by the total draw in watts.
