Built for Long Days on the Water with Lithium Power
The LiTime 36V 45Ah trolling motor battery delivers 1728Wh of usable energy in a lightweight 31.95 lb design, providing extended runtime without the bulk of traditional lead-acid batteries. Built with IP65-rated dust and water resistance, this LiFePO4 lithium battery supports reliable use in marine environments. Designed to power compatible 36V trolling motors, it is ideal for jon boats, bass boats, fishing boats, kayaks, and other small watercraft. Bluetooth 5.0 monitoring through the LiTime App helps you check key battery data in real time, while low-temperature cut-off protection helps safeguard the battery during cold-weather boating and fishing trips.
Stable Power for Strong, Steady Trolling Motor Thrust
Built for demanding trolling motor use, this 36V 45Ah lithium battery delivers stable voltage output and Max 90A continuous discharge to help compatible trolling motors maintain strong, steady thrust against wind, current, and frequent speed changes. It also supports Max 225A peak discharge for 1 second, helping handle brief power surges on the water.
Bluetooth 5.0 —Monitor Your Lithium Battery in Real Time
Stay connected to your battery through the LiTime App with real-time data on state of charge, voltage, current, power, and other key battery information. Before departure, during fishing trips, or while the boat is docked, Bluetooth 5.0 monitoring helps you check battery performance, track remaining battery capacity, and better plan your time on the water. It also helps reduce the risk of unexpected power loss, making your 36V 45Ah lithium trolling motor battery easier and more efficient to manage.
Cold-Weather Protection for Safer Boating
Low-temperature cut-off protection helps safeguard the LiTime 36V 45Ah trolling motor battery in cold conditions, stopping charging below 32°F / 0°C and discharging below -4°F / -20°C. When powering compatible 36V trolling motors, this protection could reduce battery stress in low temperatures and supports safer operation during cold-weather fishing or winter boating trips. Paired with durable LiFePO4 chemistry, it delivers dependable power when temperatures drop on the water.
