10 Best Trolling Motor Batteries 2025 in the United States

The LiTime 12V 100Ah Group 24 lithium battery is a solid choice if you need a reliable and lightweight power source for trolling motors, RVs, or solar setups. Using LiFePO4 technology, it offers higher energy density and longer life compared to traditional lead-acid batteries. Weighing only about 22 pounds, it’s much lighter and smaller than equivalent lead-acid options, making installation easier without sacrificing capacity. The built-in Bluetooth feature is a standout, allowing you to monitor battery health and performance easily via a smartphone app, which helps prevent damage from overcharging or extreme temperatures. Its durable build includes automotive-grade cells with certifications and an IP65 waterproof rating, meaning it can handle outdoor and rough conditions well.

This battery is not designed for starting engines or use in golf carts, so it’s best suited for energy storage and powering trolling motors or similar devices. The Bluetooth activation requires initial charging with a compatible lithium charger, which could be a small extra step for first-time users. The product comes with a reassuring 5-year warranty and responsive customer support, adding peace of mind for long-term use. If you want a compact, safe, and smart battery solution that lasts and is easy to maintain for trolling motors or RV applications, this LiTime battery fits the bill nicely.

The Renogy Deep Cycle AGM Battery is a 12-volt, 200Ah battery built with absorbent glass mat (AGM) technology, making it maintenance-free and resistant to acid leaks. This type of battery is known for durability and safer use compared to traditional flooded lead-acid batteries. It offers a strong discharge current, capable of handling up to 2000A max, supporting devices like trolling motors or RV appliances well. With a low self-discharge rate of just 3% per month, the battery can hold its charge for extended periods, which is great if you don't use it daily. It also performs reliably across a wide temperature range, staying efficient even in colder conditions.

The battery is quite heavy at around 128 pounds, which is typical for its capacity but might be cumbersome if you need to move or install it frequently. It's designed primarily for upright installation, so placement options are somewhat limited. The battery excels in durability and steady power output, making it best suited for users who need a robust, long-lasting power source rather than a lightweight or portable option. If you need a dependable battery for trolling motors in RVs, marine setups, or off-grid systems, this Renogy model offers solid performance with minimal upkeep. However, if you prioritize lighter batteries or those designed for frequent transport, you might want to consider smaller or lithium alternatives.

The LiTime 36V 100Ah LiFePO4 battery is a strong choice for powering trolling motors, especially if you want a reliable and long-lasting battery. It offers a solid 100Ah capacity at 36 volts, which means it can provide plenty of power for your boat or marine equipment over many hours. The battery is designed with a built-in Battery Management System (BMS) that provides over 20 types of protections, including temperature control and overload recovery, helping to keep it safe and extend its lifespan. One neat feature is Bluetooth monitoring, which lets you check the battery's status in real time using a smartphone app. Its IP65 rating means it’s well protected against water and dust — great for marine use.

The battery supports up to 15,000 charge cycles, significantly more than standard lead-acid batteries, making it cost-efficient over the long term. On the downside, it weighs about 63 pounds, which is heavier than some alternatives and might be harder to move around. Also, the battery dimensions are quite large, so make sure you have space for it on your boat or RV.

It requires a lithium-compatible charger and an initial activation charge, which is something to keep in mind if you’re used to simpler setups. While it’s pricier than basic batteries, its durability, safety features, and smart technology make it well suited for serious anglers or marine users who want reliable power and monitoring options.
