The Trolling Motor 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 2,000 cycles. Built with UL1642 certified Lithium Iron Phosphate cells, 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 12.8V 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 IP65 water resistant.

TM3190 12.8V 90Ah Lithium Ion Battery is a drop in replacement for BCI group 31 lead acid batteries for marine trolling motors. Featuring 207 reserve minutes of energy, it is the same energy as a typical AGM battery in a standard Group 31 case. (13″ L x 6.81″ W x 8.43″ T)

It features an internal battery management system that insures long life and trouble free service, all safely sealed inside a lightweight box. This BMS system monitors for over voltage, over temperature, over current, under voltage, and short circuits. In addition robust cell balancing keeps the pack at its peak capacity.

Charging is simple because your existing 12V AGM or Gel battery compatible charger will work fine.*

In spite of all the power contained in this battery, it still ultra lightweight at an amazing 27 pounds!

*Ensure the charger’s float voltage is 13.5V or less. Do not “de-sulfate” any lithium ion battery.
