Any modern electric trolling motor should function with any deep cycle 12-volt marine battery. However, if you’re looking for a longer lifespan and runtime, you’ll want to invest in lithium trolling motor battery, particularly LiFePO4 (lithium iron phosphate). The options include the 24v and 36v lithium marine battery, and you can find these being sold online. You just have to be discerning and make sure you are buying a high-quality battery from a trustworthy source. Moreover, you need to examine the features of the battery to make sure that it is safe and reliable for trolling motor applications.
The best 36v or 24 volt lithium trolling motor battery will depend on your needs. For instance, a 36v 40AH deep cycle battery should easily fit 36V marine trolling motors from MotorGuide, Bass Pro, Caroute, and Minnkota, and it should deliver more power than three AGM or lead-acid batteries rated at ~12V +80AH. That means it should provide more than five times the lifetime of lead-acid and AGM batteries.
A 36v 80AH lithium iron phosphate battery offers plug-and-play convenience. It’s a single module 36v lithium marine battery that will occupy less space compared to when you connect three 12v100Ah in a series. If you’re looking for a more powerful option, consider the 36v 100Ah LiFePO4 battery that can potentially offer 14 hours of use on a 36v marine trolling motor. It’s a great option for pro fishermen and those who are likely to spend many hours on the water.
A 24v 40AH deep cycle battery offers more power than two AGM or lead-acid batteries rated at ~12v +100AH, with five times the lifetime of those alternatives. Powerful 24 volt lithium trolling motor battery would be the 24v 100Ah model that can provide over 12 hours of use on 24v motors by Bass Pro, MinnKota, Caroute, and MotorGuide.
Features to consider
When searching for the best 24v or 36v lithium trolling battery, make sure that it has a battery management system and a LED charge indicator. You should also check every model’s features and performance to verify their reliability for your specific applications.
