How long does one 12-volt deep cycle marine battery last with this trolling motor?

The runtime depends on the Amp-Hour rating of the battery. Theoretically, a 50AH battery on our 55lb thrust motor will run continuously on the highest speed for an hour. See "Choose Your Motor" for run times. You can also check out our articles Calculate Motor Run Time for detailed information on this.

Note: This does not take into account environmental factors such as wind and water speed, or boat size and load.
