Pros® Lithium Trolling Battery packs long-lasting power at 1/3 the size

The Lithium Pros® TM3138-36 38.4V 38Ah Lithium-Ion Trolling Battery takes up ⅓ the space of regular batteries and gives anglers more motor space while reducing weight on their boats. The battery offers 92 minutes of usable power reserve, has a lifespan of over 2,000 charges, and is equipped with an internal battery management system for safe and efficient performance.

The lithium-ion trolling battery measures 13 inches long x 6.8 inches wide x 8.4 inches deep and weighs 32 pounds, yet provides as much trolling power as three lead-acid batteries. 12V BCI Group 27 Acid. That’s 1/3 the space and less than 1/3 the weight of legacy trolling motor power supplies.

Easy to operate while actively fishing, trolling motors are indispensable for quietly accessing shallow fishing spots or maintaining positions in the current. However, powering motors traditionally required bulky, heavy 12V batteries that needed frequent charging and had a limited lifespan.

Lithium ion batteries offer more advantages to boating anglers than lead acid batteries. They are smaller and lighter, charge faster, run longer on a charge, and typically last up to ten years, while lead-acid batteries typically last around three years.

Rated at 38 amp hours or 1459 watt hours, the Lithium Ion Trolling Battery provides 92 minutes of standby power for hours of fishing. The internal battery management system offers built-in protections against over-temperature, over-voltage, over-current and short-circuit conditions.

Built with Lithium Ion Phosphate (LiFePO4) cells tested to the UL1642 standard, Lithium Pros TM series batteries are recommended for inductive motor loads such as trolling motors, electric motors, motive power and other forms of Energy storage. They can be recharged with typical AGM battery chargers.
