10 Best Lithium Battery For Trolling Motor 2025 in the United States

The LiTime 2 Pack 12V 100Ah Trolling Motors Lithium Battery is designed specifically for users seeking reliable power for their trolling motors and other applications. One of its standout features is the Bluetooth 5.0 connectivity, allowing you to monitor battery status in real-time through your smartphone. This is particularly handy for keeping track of voltage and capacity while out on the water. With a remarkable capacity of 100Ah and a lightweight design of just 22.2 lbs, it offers a significant energy boost compared to traditional lead-acid batteries, effectively doubling the driving range, which can enhance your boating experience.

Safety is a strong point, too, thanks to its advanced Battery Management System (BMS) that provides triple protection against common issues like overcharging and short circuits. The low-temperature cut-off feature ensures that the battery can be safely used in colder conditions, making it suitable for various environments.

Despite its lightweight nature, the battery is still somewhat bulky and may require careful handling during transport. Additionally, while the battery is versatile for many applications, it’s not meant for starting engines or specific use cases like golf carts, which might limit its appeal for some users. The charging time and activation procedure could also be a little confusing for users new to lithium batteries, as it requires a specific type of charger to activate the Bluetooth function after purchase. Lastly, while the option to expand the battery system is a great feature for those looking for more power, it may be overwhelming for beginners who are just looking for a straightforward solution.

The LiTime 12V 100Ah TM LiFePO4 battery is a robust choice for trolling motors, yachts, marine applications, RVs, and home energy systems. Key strengths include its high battery capacity of 100Ah and stable voltage of 12.8V, making it suitable for a range of demanding uses. It offers an impressive cycle life of up to 15,000 cycles at 60% depth of discharge, ensuring long-term durability and reliability.

Additionally, it features a fast charging time and weight of only 22.1 pounds, making it relatively easy to handle and install. Safety is a standout feature with its triple protection Battery Management System (BMS), which guards against overcharging, over-discharging, overheating, and short circuits, plus a low-temperature cut-off function for added safety in harsh conditions. The auto sleep mode is particularly useful for reducing self-discharge, maintaining battery charge when not in use.

However, potential drawbacks include the relatively high upfront cost and the need for proper handling due to its lithium composition. Its expandability up to 48V 400Ah is a bonus for those needing more power. With a 5-year warranty and strong customer support, this battery offers peace of mind and reliable performance for serious trolling motor users and other applications.

The OGRPHY 36V 100AH lithium battery is a strong choice if you need a reliable power source for your golf cart or a trolling motor. It offers a good battery capacity of 100Ah at 36 volts, which can comfortably power a 3kW golf motor for about 30 miles, enough to cover a full round of golf. One standout feature is its long cycle life—over 5000 deep charge cycles and a 10-year lifespan—meaning it should last much longer than typical lead-acid batteries. The built-in 200A battery management system (BMS) provides strong protection against issues like overcharging, overheating, and short circuits, making it safer to use. You also get a smart Bluetooth connection to monitor battery health on your phone, plus an LCD monitor for real-time updates while you’re out. Charging is convenient with the included 25A onboard charger, which supports quick and safe recharging.

On the downside, the battery weighs about 63.5 pounds, which is fairly heavy and may require some effort to install and move. While it’s marketed mainly for golf carts, its robust power and protections make it suitable for other uses like trolling motors or small RV setups, but it might be overkill if your needs are very light. This battery represents a solid investment for those seeking durability, safety, and good monitoring features, though users should be prepared for the weight and upfront cost associated with its high performance.
