What Is Trolling Motor Battery


When it comes to batteries for electric trolling motors, you may choose from a wide variety of models. Traditionally, anglers have relied on marine deep-cycle batteries such as lead-acid wet cells, absorbed glass mat (AGM) cells, and gel cells. However, there is a new alternative that has several positive features. You should seek a Trolling Motor Battery if you plan on using your trolling motor often. In contrast to a beginning battery, which is until utilized short spurts of power, deep-cycle batteries are designed to be gradually depleted and replenished. Choosing the right trolling motor battery for your situation requires consideration of the following factors:


Choosing the Right Battery:

Consider your battery’s kind, its ampere-hour rating, and your financial constraints. We need to first determine the power requirements of your trolling motor at different speeds in order to choose the appropriate trolling motor battery. Your electric trolling motor requires a battery (or batteries) with high amperage hours (Ah) ratings. Avoid using CCA-only-rated batteries. Cold Cranking Amps (CCA) measure a battery’s ability to provide the current needed to crank a turbo or petrol engine to start. AGM batteries are a kind of lead acid battery; however, they are maintenance-free because of their sealed design.

Lithium Marine Batteries - Deep Cycle & Starter Battery for Boat

A high-quality battery, if cared for, should last for at least two to three years. Consumers often associate huge and heavy automobile batteries with starting batteries, however deep cycle batteries also suit this description. It takes a deep-cycle battery, which is specifically designed for low-current discharge over a lengthy period, to power a device.  Starter batteries, on the other hand, may discharge a high current for a little period. It’s not good for a starter battery to be discharged to below 50% and then repeatedly recharged. Starter batteries won’t hold up for long under these conditions.


Both battery and the trolling motor will eventually wear out from the constant use of a starting battery. The lithium iron phosphate (LiFePO4) deep-cycle battery is the kind used in trolling motors. As its name implies, it is designed to power trolling motors at a low and consistent rate. While 12-volt lithium trolling motor batteries are the norm, 24-volt batteries do exist. When batteries are linked in series, their voltages are added. When many batteries are linked in parallel, their combined amp-hour (Ah) capacity is calculated.


The output of two 100 Ah 12-volt batteries linked in parallel is 200 Ah. The voltage of a trolling motor may range from 12 to 36 volts. There is no universal rule for determining the ideal battery amperage hour rating outside of the context of its intended use. If you plan on using the at full The speed for two hours straight, you’ll need. However, a battery with a rating of 50-100 AH will be enough for two hours of use at slower speeds with rests. Estimating your battery requirements with the use of the above-mentioned calculation can help you to choose the one that works best for you.
