So your choice of battery is going to depend 36V lifepo4 battery on what you can afford. If you want a battery that is durable and delivers excellent performance, AGM batteries would be the best choice. Lithium-ion batteries are lighter than both lead-acid and AGM batteries. They also charge more quickly and have a longer life than the two batteries.
Best Trolling Battery For Larger Vessels
The Power Series AGM is their top-of-the-line Group 27 deep cycle battery. With improved efficiency and storage, this battery is rated to fish all day and take a beating. The AGM has a higher cold cranking rating and longer reserve time than lower-priced models. Lithium batteries weigh 60% less than equivalent lead-acid models—a 100Ah lithium battery averages 26 lbs vs. 65 lbs for AGM. Reduced weight improves boat stability, fuel efficiency, and payload capacity.

Another thing you should care about the boat trolling motor battery is its group number. Oftentimes you’ll see the trolling motor battery marked with group 24, 27, 31, and etc. If you don’t want to replace the trolling motor batteries every year or every a few years, choose a good quality AGM battery which can last around 4 years, no maintenance needed. Having decided on the best type of battery for trolling motor, your next move would be selecting one that can perfectly fit your boating needs with enough power but not overkill.
The MR127 is at its best when paired with trolling motors with around 30-40lbs of thrust. With these motors expect up to 12 hours of runtime on lower settings, 7 hours on medium, and 2.5 hours on high settings. In fact, the ODYSSEY is one of the most versatile and highest-quality trolling motor batteries you can buy.
What many folks don’t know is that 36V controllers are made to work in 36V environments and give you way more leeway in one battery degrading your whole system. First, you have to understand in parallel or series systems, when one battery goes down, the whole thing is down. If, on the other hand, you want a light and high-performing battery that will last you many years, lithium is the way to go. I recommend you also read reviews and learn about other users’ experiences with customer support. It’s great if you know you can pick up your phone and get any advice you may need. In this case, your motor shouldn’t draw more than 60 Amps, preferably closer to 50 Amps.
