Things to Consider When Buying a Trolling Motor Battery

Finding the right battery for your trolling motor can be a bit of a challenge. However, whenever you’re looking to make a well-informed buying decision, here some aspects to check.

Battery size

Batteries for trolling motors come in different sizes. You must find the right size for your trolling motor and balance it with its power requirements. Check this out before you purchase so that you don’t have issues later on.

Voltage

Trolling motors need either 24V or 12V depending on their power requirements. Motors that have higher thrust will require up to 24V. If you need a high thrust option, you may need to double 12V batteries. Whatever the case is, always check for the voltage requirements of your trolling motor before purchasing a battery.

Run time

The question that begs an answer here is: how much run time do you need? This has to do with the duration you run the trolling motor during each use. If you run for extended periods, then you need a battery that can match up to your requirements.
