Lithium Battery Selection for Marine Trolling Motors: 12V/24V/36V — Matching Runtime and Thrust

Choosing the right lithium-ion trolling motor battery may have more impact on your day on the water than choosing the motor itself. Get the voltage wrong, and the motor won’t even run properly. Underestimate the amp-hour capacity, and you’ll be heading back by early afternoon. Pick the wrong battery type, and charging and discharging both become a headache. This article breaks down the selection logic from three angles: voltage, capacity, and runtime calculation.
