The trick to rigging a Marine Battery boat with a trolling motor battery is ensuring the system will last for a long day of fishing. Follow the trolling motor manufacturer’s instructions for the amp-hours, group, and the number of deep cycle batteries required to power the motors all day. The latest and greatest trolling motor batteries are made of lithium iron phosphate. Unlike heavy, bulky lead-acid batteries, lithium is lighter and more compact. The compound also handles power more efficiently and lasts considerably longer with a greater tolerance for recharging. The downside is lithium batteries cost three times as much as a lead-acid battery.

The higher the voltage, the more pounds of thrust a motor can provide. Going with a higher voltage motor means you will need to run it off of more than 1 battery. Run at least 2 batteries for 24v motors, and 3 for 36v electric motors. The Universal Power Group offers this Solar Wind battery at a chopped down price. It is very similar to our #1 ranked VMAX battery, in that it offers 100 amp hours, and uses the absorbed glass mat.
The Best Trolling Motor Batteries Of 2025
It’s impressive how good my screen looks and how it’s good all day. We spent a lot of time testing their batteries in a variety of situations from powering electronics, starting an outboard and powering a trolling motor. Their battery management system (BMS) is very well designed, and we never encountered the first problem.

For kayaks or small craft, consider lightweight options like Ionic 12V 50Ah (14 lbs). Always secure batteries with vibration-resistant mounts to prevent movement in rough waters. The Marine Group 31 battery is a deep cycle lead-calcium flooded marine battery that is more powerful version of the group 24 battery above. Its dimensions are 13” x 6.75” x 9.5” and it weighs in at 60 lbs. As with the smaller version, the sealed unit allows the battery to be mounted up to a 45-degree angle without the need to worry about spills and leaks. Molded-in stainless steel studs and hex nuts help create a fluid connection and prevent corrosion to the exterior power joints.
As you can see, choosing a lithium battery is an investment to consider. You need to pay a lot, but you get reliable equipment that will work for you for many years. On the other hand, you need to save money on high-quality equipment, which excludes fast decisions.
However, if you have a 36V system you have a lot more leeway with one cell shutting down the battery. Ultimately, 36V systems in parallel are actually a better choice for anglers than three 12V batteries in a series. Your 12-volt batteries have 12V controllers and are somewhat limited on managing a 36V system. A 36V controller is way better equipped to handle your 36V power environment in each battery and as a system. One of the most notable features is the battery’s Bluetooth 5.0 connectivity.
