Being an AGM also means the battery handles vibrations and shocks without lowering performance. If you’re on choppy water or driving at higher speeds the battery performance won’t take a hit, and you won’t need to worry about leakages either. It’s completely sealed and won’t require fluid top-ups, so there should be very little to worry about in terms of maintenance. Of course, a general rule of thumb is that the higher the Ah number the better, as it means you’ll get even more charge from the battery so you can fish for longer. Higher Ah ratings often mean a more expensive battery, although this is often worth the investment when fishing frequently.

The main battery of the boat should also be reserved for cranking and is designed to start with low amperage. As the battery for the trolling motor will require regular discharge and recharge when compared with the main boat battery it allows the main boat battery to last longer. Any common deep cycle battery may vary between 60 and 70 pounds. And by choosing the lithium-ion trolling motor battery, you can reduce the weight but only at a higher price. Overall, the Odyssey Trolling Thunder battery is an excellent choice for those looking for a high-quality trolling motor battery that will provide reliable power and performance. For a 55lb thrust trolling motor, a 12V 100Ah battery is typically sufficient for most recreational uses.

Trolling Motor Sizing For Different Boat Lengths And Weights

Each boat has unique properties or requires different power equipment depending on the engine capacity, size, engine, etc. Whether you intend to use the trolling motor battery for kayak or other boats, it’s important to follow some tips to prolong its lifespan and make the best use of it. To calculate the accurate trolling motor battery life, you need to check out the battery’s amperage hour (Ah) rating and the amperage draw of the trolling motor. If you are going with the lead acid trolling motor battery, be sure to get the sealed batteries instead of the flooded ones if you want a maintenance-free trolling motor battery. A deep cycle battery is designed to be fully discharged and then recharged.

Customers appreciate the battery’s lightweight design, noting it has the weight of a standard lead acid battery and is easy to carry, making it suitable for short trips. Customers find the battery works well and offers good value for money. They appreciate its battery life and size, with one customer noting it’s very compact and another mentioning it saves space. Good for up to 600 cycles, the LXD100 also features Deep Cycle technology, which provides a consistent flow of power and allows up to 70 percent discharge without damaging the battery. Priced way above any other products mentioned here, the BlueFusion GX100 has made it onto our list as it’s a Lithium-ion battery.

The VMAX MR127 12V 100 Amp Hour Deep Cycle Battery is our best overall pick. The VMAX is an AGM (absorbed glass mat) deep-cycle lead acid battery requiring no maintenance. With 100 Amp Hours, you’ll have enough power to motor around the lake all day and run whatever accessories you wish. Using a trolling motor battery exclusively for the trolling motor instead of using the main battery of the boat has several upsides to it. Since trolling motors are much smaller than traditional engine motors they require less power to get them started and to keep them running.
