10 Best Trolling Motor Batteries 2025 in the United States

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.

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 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.
