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.

This Battle Born 270Ah 12V lithium iron phosphate (LiFePO4) battery is a strong choice for trolling motor users who want reliable, long-lasting power. Its 270 amp-hour capacity offers plenty of energy for extended outings, making it well-suited for fishing or boating trips. The LiFePO4 battery type is known for safety, stability, and a long service life compared to traditional lead-acid batteries. At 12 volts, it's compatible with most trolling motor setups. The battery weighs 81 pounds, which is on the heavier side but typical given its high capacity and solid build.

Thanks to Battle Born's Dragonfly IntelLigence technology and Bluetooth connectivity, you can monitor the battery's status wirelessly, which adds convenience and helps protect your investment by preventing over-discharge or other issues. The battery's construction is robust, designed for marine and off-grid use, so it should hold up well against the elements and rough handling. While this battery offers excellent performance and advanced features, it may be more expensive and heavier than simpler options, which might matter if portability is a priority. This battery is ideal for serious anglers or boaters who need dependable power, smart monitoring, and durability, though casual users might find it more than they require.

The LiTime 12V 100Ah LiFePO4 battery is a solid choice for trolling motors and marine applications. It uses high-quality lithium iron phosphate cells, which last much longer than traditional lead-acid batteries—up to 15,000 cycles at lower depths of discharge. This means you can expect years of reliable use without needing frequent replacements. The battery has a built-in Battery Management System (BMS) with multiple protections against overcharging, overheating, and even harsh environments like salt spray or dust, making it durable and safe for boats and outdoor use.

Its voltage of about 12.8V is standard for trolling motors, and the 100Ah capacity provides a good balance between power and weight (about 22 pounds). Another handy feature is the auto sleep mode, which helps keep the battery charged when not in use by reducing self-discharge, so you won’t find it drained after storage. This battery is also expandable in larger systems if you want more power for bigger setups like RVs or solar power.

At 22 pounds, it is heavier than some lithium batteries on the market, which might matter if you need something ultra-light. The product comes in a 2-pack, which could be convenient or more costly upfront depending on your needs. Backed by a 5-year warranty and positive customer reviews, this battery delivers strong performance and peace of mind for trolling motor users seeking a durable and long-lasting power source.
