The TM3190is an upgrade for BCI Group 31 lead acid batteries. It is intended for use with 12V trolling motors and 12V marine electronics. Featuring 207 reserve minutes of energy, it is the same energy as a typical group 31 AGM battery. (13" L x 6.81" W x 8.43" T)
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 2,000 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 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.
Charging is simple because your existing 12V AGM battery compatible charger will work.*
NOTE: Not intended for engine start or charging from an alternator.
*Insure the charger's float voltage is 13.6V or less and the output voltage never exceeds 14.6V. Do not "de-sulfate" any lithium ion battery. See instructions for more details.
