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 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.
