TM133 12V 33Ah Lithium Ion Battery

  • Perfect for kayaks!
  • Excellent for Lights and Electronics
  • 12V
  • 33Ah (422 Whr)
  • 65 Reserve Minutes 
  • BCI Group U1 size, 7.75"x5.12x6.37"
  • 10 lbs

The TM133 is an upgrade for BCI group U1 lead acid batteries.  It is intended for use with 12V trolling motors and 12V marine electronics.  Featuring 65 reserve minutes of energy, it is 30% more runtime than a typical U1 marine lead acid battery. At only 10 lbs and (7.75" L x 5.12" W x 6.37" T), its the perfect size for kayaks!

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.*

*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.

12 Year Warranty

All Lithium Pros products carry a 60 day risk free guarantee. If you are not satisfied with your purchase for any reason, you can return it to where it was purchased (with proof of purchase) for an exchange or full refund*. We have full confidence in our products, and are sure you will too!

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.
