The TM series

The Trolling Motor ("TM") series of batteries is made for trolling motor and other deep cycle marine applications that can benefit from fast recharge, superior charge efficiency, weight reduction, and cycle lives beyond 3,000 cycles. Built with Lithium Iron Phosphate cells tested to the UL1642 standard, the TM series of batteries is recommended for inductive motor loads such as trolling motors, electric motors, motive power, and other forms of energy storage.

The TM series of 36V lithium ion batteries feature an internal battery management system designed to auto balance the cells and protect for over temperature, over voltage, under voltage, over current and short circuit conditions. They can be charged with typical AGM battery chargers (see restrictions and notes) and are IP67 water resistant.

The TM series also features Bluetooth connectivity.  Download the LP Battery View App from Lithium Pros in the App store.  This App shows you Time Remaining, State of Charge, voltage, amperage, and temperature for each of your TM series batteries.

38.4V LiFePO4 compatible charger is required.

Why Lithium Pros?

MORE POWER

Power is the measure of the volume at which energy can be delivered.  Lithium Pros’ batteries have always been high power. 

Lithium Pros' batteries hold a higher voltage while loaded and recharge faster. That means a hotter ignition, faster starts, and more watts for your accessories.

LIGHTER WEIGHT

Lithium Pros' batteries are three times the energy density of comparable lead acid batteries. High energy means you can do more in the same footprint and do it with less weight.

The result is a lighter battery. In fact, some models are so light they float, making them ideal for racing and marine use.

FASTER RECHARGING

Lithium Pros’ lithium-ion batteries accept charge current up to five times faster than lead-acid batteries, and in many cases Lithium Pros’ batteries recharge in as little as an hour.

LONGER BATTERY LIFE

Lithium Pros’ LiFePO4 batteries provide over five times the cycle life at 80% DoD (depth of discharge) compared to standard lead-acid batteries, and easily handles 2,500 cycles and more.
