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 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.

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.
