10 Best Trolling Batteries 2025 in the United States

The LiTime 36V 100Ah LiFePO4 battery is designed specifically for trolling motors and marine use, making it a solid choice for boaters and RV owners needing reliable power. It offers a high capacity of 100 amp-hours and supports surge currents up to 500A, which means it can handle demanding electric outboard motors including popular brands like Torqeedo and Yamaha. The built-in battery management system (BMS) protects the battery with over 20 safety features such as low temperature cut-off and overload recovery, helping to extend its lifespan and maintain safe operation. Users can also monitor battery status via Bluetooth, which adds convenience for managing power on the go.

Its rated lifespan is excellent, with 4,000 to 15,000 cycles, and it is built to withstand harsh environments with an IP65 waterproof rating and temperature tolerance from -20°C to 60°C. However, the battery is relatively heavy at about 63 pounds and measures around 20 inches wide, which might be bulky for smaller setups or users seeking lightweight options. It also requires an initial activation charge with a compatible charger, meaning some setup is necessary before first use.

For serious trolling motor users who value durability, smart features, and strong power output, this battery is well suited. Those prioritizing long life and protection combined with modern monitoring will find this battery meets those needs well, although users sensitive to weight and size should consider these factors carefully.

The LiTime 24V 50Ah LiFePO4 Deep Cycle Battery is a solid choice for anyone needing reliable power for trolling motors, especially in boats, yachts, or RVs. It uses lithium iron phosphate (LiFePO4) technology, which is known for being lightweight and safe compared to traditional lead-acid batteries. At 24 volts and 50 amp-hours, it provides a good balance of power and capacity suitable for medium thrust trolling motors (70-100 thrust). The battery is compact and relatively light at 21 pounds, making it easier to handle and better for small spaces compared to carrying two 12V batteries. Its built-in battery management system (BMS) protects against common issues like overcharge, over-discharge, and short circuits, contributing to a long lifespan of up to 10 years and thousands of deep charge cycles—far more than typical lead-acid batteries.

An added convenience is the Bluetooth 5.0 feature that lets you monitor battery status in real time, helping avoid unexpected power failures. It also includes low-temperature cutoffs to prevent damage when used in cold climates. While lithium batteries usually require less maintenance than lead-acid types, they still need proper charging equipment and care to reach their lifespan potential. This battery is well-suited for users who want a durable, lightweight, and smart-powered option for their trolling motor or marine applications, especially if space and weight are concerns.

The Renogy Deep Cycle AGM 12 Volt 100Ah Battery is a solid choice for trolling motor users, campers, and RV enthusiasts looking for a maintenance-free power solution. With its lead-acid AGM composition, it boasts a robust voltage of 12 volts and a substantial capacity of 100Ah, which means it can run for extended periods without frequent recharging. This battery is particularly suited for environments with extreme temperatures, working efficiently from -4°F to 140°F (-20°C to 60°C). With a reserve capacity (RC) that allows it to sustain stable power output, it is capable of safely powering various appliances like fridges, microwaves, and laptops, making it versatile for off-grid applications.

The unit is hefty at 63.9 pounds and has dimensions of 13.1 x 6.9 x 8.6 inches, which may require careful planning for installation and handling. One of the standout features is its minimal self-discharge rate of less than 3% per month, reducing the need for constant recharging when not in use. The battery can handle a max discharge current of 1100A for short bursts, which is beneficial for high-drain devices. The Renogy battery is also designed for safety with its sealed and stable construction, eliminating the need for intricate troubleshooting.

However, its weight and size could be a downside for those needing a more compact and lightweight solution. Additionally, while it offers good performance, some users might prefer lithium batteries for even longer lifespans and lighter weight. This Renogy battery achieves a balanced trade-off between performance, safety, and maintenance-free operation, making it a reliable choice for most trolling battery applications.
