How to Choose a Battery for Trolling Motor

Voltage Options (12V, 24V, 36V)

You need to match the voltage of your battery for trolling motor to your motor’s needs. Most trolling motors use 12V, 24V, or 36V systems. A 12V setup works for small motors with 30–45 lbs of thrust. If you want more power, a 24V or 36V system is better. Higher voltage motors give you more thrust and run more efficiently. For example, a 24V 80 lb thrust motor with a 54Ah battery can run up to 14 hours at moderate power. Always check your motor’s manual before you buy a battery.

Amp-Hour Rating and Group Size

The amp-hour (Ah) rating tells you how long your battery for trolling motor will last. A higher Ah rating means longer run time. Most anglers choose at least a 100Ah battery. Group size matters too. Group 27 or higher is a good choice for most setups. Here’s a quick guide:

Motor Thrust

Recommended Battery Type

80 lb

Lithium

100–125Ah

2–3 hours

112 lb

Lithium

125–150Ah

1.5–2.5 hours

Tip: Lithium batteries can use their full capacity, so a 50Ah lithium battery may last as long as a 100Ah lead-acid battery.

Matching Battery to Motor Thrust

You want your battery to match your motor’s thrust. More thrust means you need more voltage and capacity. For example:

  • 30–45 lbs thrust: 12V, 100Ah battery

  • 70–86 lbs thrust: 24V, two 12V 100Ah batteries in series

  • 100–112 lbs thrust: 36V, three 12V 100Ah batteries in series

A higher capacity battery keeps your motor running strong, even at high speeds. If you use your trolling motor at full throttle, you’ll need more amp hours for longer trips.

Price and Value

Batteries come in different price ranges. Deep cycle batteries cost $175–$230. AGM batteries are around $1,225. Lithium batteries cost more up front, sometimes over $2,000, but they last much longer. For example, a lithium battery can last up to 20 times longer than a lead-acid battery and weighs about 40% less. You save money over time because you replace them less often. Some lithium models, like the 24V 150/200Ah LiFePO4, offer 6000 cycles, smart safety features, and work in hot or cold weather.

Powering Accessories

Some batteries can power more than just your trolling motor. You can use them for fish finders, GPS units, and other electronics. AGM and lithium batteries work well for this because they deliver steady power and need little care. Lithium batteries also charge fast and have built-in safety systems. If you want to run lots of accessories, pick a battery with a high amp-hour rating and reliable performance.

Note: Always check your boat’s needs before you buy a battery for trolling motor. The right choice helps you fish longer and keeps your gear running all day.
