10 Best Trolling Motor Batteries 2025 in the United States

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.

The Litime 12V 100Ah LiFePO4 trolling motor battery is a solid choice for boaters and outdoor enthusiasts who want reliable, long-lasting power. It uses lithium iron phosphate cells, which provide a longer lifespan and more deep cycles (up to 4000+ cycles) compared to traditional lead-acid batteries. This means it can handle many charge and discharge cycles without losing much capacity, making it an excellent investment if you use your trolling motor often. Weighing about 22.2 pounds, it’s relatively light for a Group 31 size battery, which helps keep your boat faster and more maneuverable.

The battery also offers smart Bluetooth monitoring, allowing you to check its status and control functions easily from your phone—very handy for managing power on the go. Built-in low temperature protection and over 20 safety features make it durable and safe for marine environments, including rain and saltwater exposure, thanks to its IP65 rating. Its 1280Wh energy capacity gives you roughly double the range compared to typical lead-acid batteries, which is great for longer trips. It can also be expanded to create larger battery banks if you need more power for bigger boats or additional equipment.

However, this battery isn’t designed for starting engines or use in golf carts, so it’s purely for trolling motors and energy storage. Also, initial setup requires a special charger to activate the Bluetooth feature, which might be a bit technical for some users. The price and need to order three batteries as a pack could be a consideration for those on a budget. The Litime battery represents a lightweight, durable, and smart-powered option for trolling motors and marine use, especially suited for those seeking a long-lasting, low-maintenance battery with modern monitoring features.
