10 Best Trolling Motor Batteries 2025 in the United States

The LiTime 12V 100Ah TM Low-Temp Protection LiFePO4 Battery is designed specifically for trolling motors and other marine applications, making it a strong candidate for those who spend time on the water. One of its key strengths is its durability; the battery includes a built-in BMS (Battery Management System) that offers triple protection against dust, water, and salt, making it suitable for harsh marine environments. Additionally, it has a low-temperature cut-off feature, ensuring safe operation even in cooler conditions.

Another advantage is its impressive lifespan. With up to 4,000 cycles at 100% depth of discharge, it significantly outlasts traditional lead-acid batteries, which usually only last around 3 years. This can result in long-term cost savings and reliability, especially for avid boaters. The battery also offers automatic overload protection, allowing it to recover from overload situations without requiring manual intervention.

However, there are a few drawbacks to consider. Weighing in at 46 pounds, it may be heavier than some users prefer, and its size could pose challenges for compact installations. The battery is primarily designed for deep cycle applications, which may not be the best fit for those solely looking for a starting battery. Lastly, LiTime provides a 5-year warranty, which adds a layer of assurance for new buyers. This battery is an excellent choice for those who need a reliable, long-lasting power source for trolling motors and similar applications, but potential buyers should assess their specific space and weight constraints before committing.

The LiTime 12V 50Ah Plus LiFePO4 Lithium Battery is a lightweight and versatile option for trolling motors and various other applications like RVs, boats, and camping. Weighing only 11.57 pounds, it is significantly lighter than traditional lead-acid batteries, making it easy to handle and install. With a capacity of 50Ah, this lithium battery offers a high energy density and stable performance.

The built-in Battery Management System (BMS) protects against overcharging, discharging, and short-circuiting, ensuring safety and reliability over its 10-year lifespan. It also boasts an impressive 4000+ charge cycles, which is much higher than the 300-500 cycles of lead-acid batteries. With a voltage of 12V and a reserve capacity that allows it to maintain a flat discharge curve above 12.8V, this battery provides consistent power output for its entire capacity.

Despite its relatively high upfront cost, the long-term value is notable due to its extended lifespan and efficiency. However, it should not be used as a car, starting, or golf cart battery. In summary, the LiTime LiFePO4 battery is an excellent choice for those needing a durable, lightweight, and high-performing power source for their trolling motor and other similar applications.

The Interstate Batteries Marine/RV Battery (31M-AGM) is a highly versatile 12V 100Ah battery designed to meet the dual purposes of starting your motor and powering your trolling motor. With 925 Cold Cranking Amps (CCA), it offers robust performance for starting applications. The pure lead AGM technology sets it apart, providing 2-3 times longer battery life compared to conventional batteries, which is great for those looking for longevity and reliability.

Its high-cranking and extreme deep-cycle power make it suitable for both boats and RVs, allowing you to run multiple accessories without worrying about power loss. The battery's build quality is robust enough to withstand rugged conditions, making it a reliable option for outdoor enthusiasts. However, the weight of this battery may be on the heavier side, which might be a consideration if ease of handling is important to you.

Additionally, while the pure lead construction offers superior performance, it might come at a higher price point compared to standard batteries. If you're looking for a dependable power source with excellent longevity and deep-cycle capabilities, this battery could be a solid choice for your marine or RV needs.
