Think of it as a measure of how much time 24V lifepo4 battery your trolling motor battery will give you on the water. Max amp draw shows how much power your trolling motor needs when it’s running at full speed. Specifically, a trolling motor battery with more amp-hours than your motor’s max amp draw. Also listed as dual-purpose batteries, marine AGM batteries such as the 31M-AGM can crank engines and drain deeply on a trolling motor.

 

The Best Portable Power Stations Of 2025, Tested And Reviewed

 

Its patented SPIRALCELL technology is an assurance that it has more running time, can be recharged fast, and it has longer life compared to marine batteries or any RV batteries. Optima batteries are tightly wounded to minimize plate movement and damages caused by rough conditions. It’s also spill-proof hence it is maintenance free as well as environmentally friendly.

 

It weighs around 75 lbs, and the dimensions are 12.9 x 6.8 x 8.5 inches and have a power capacity of 120 AH. Hence, it is an ideal trolling motor for your Jon boat, giving more power with higher amperage. The service life of this trolling motor is about 8 to 10 years.

 

Marine Efb Batteries

 

With so many different types of batteries available on the market, choosing the right one can be a confusing and overwhelming process, even for experienced boaters. Dual-use batteries – are the compromise between a starting and a deep cycle battery. Deep cycle batteries – are essentially the opposite of a starting battery. Designed with thick, solid plates bathed in a catalyst medium, they can’t produce enough instantaneous power to start an outboard. But they excel at delivering steady power over a long time, making them ideal for trolling motors.

 

Each of these options has unique benefits and applications, ensuring that there is a battery to meet every mariner’s need. The has been constructed with top technology, which regards the acid inside the battery. None other than the Absorbed Glass Mat technology allows for a low-maintenance and spill-proof battery. It provides 12 volts with 34 Ah and can be safely mounted in any given position. Not only is this affordable, but it also cuts any risk of corrosion or leakage due to the highly porous absorbent glass mat.

 

However, a more powerful trolling motor for heavier boats may require 24 Volts, so you’ll need two 12V batteries in that case. The fact you can get several hours at top speeds showcases just how impressive this battery is – smaller batteries just don’t offer anywhere near the same run time at top speeds. Take things down a notch and expect the battery life to last even longer, giving anywhere between 6-8 hours depending on the motor draw and water conditions. Even with this, expect a good bit of charge to be left, as the battery will struggle to completely discharge unless used all day at high speeds.

 

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.
