TM-Series

Pricesely Designed Trolling Batteries

LiFePO4 Power for Trolling Adventures

The TM Series from Lithium Pros delivers genuine LiFePO4 performance to boaters who want trustworthy power at a price that makes sense. Each lithium iron phosphate pack weighs far less than comparable lead-acid banks, recharges in a fraction of the time, and holds its voltage under heavy trolling loads. That means more hours on the water and less downtime at the boat ramp.

 

Marine-Ready Construction

Salt spray, pounding waves, and summer storms are no match for the TM Series. The rigid case is sealed to IP67, keeping electronics dry even during occasional submersion. Every unit is engineered to meet the ABYC E-13 standard, ensuring the battery integrates cleanly with existing marine wiring and safety practices.

Intelligent Protection

Inside, an advanced Battery Management System monitors every cell continuously. Intelligent cell balancing continuously equalizes voltages, so the full capacity remains available after thousands of cycles. Safety circuits instantly isolate the pack if they sense abnormal voltage, current, or temperature, giving you peace of mind on long runs.

 

Cold-Weather Confidence

For boaters in warm and mild climates, the TM Series relies on its thermal lockout to stop charging when the pack is frozen. Simply bring the battery above 32 °F, and normal charging resumes automatically. 

 

Designed by Lithium Pros

All design work, firmware, and validation testing is handled by the Lithium Pros engineering team. Production takes place in an certified facility that builds exclusively to our specifications. Tight control of materials and processes lets us offer an industry-leading warranty to the original purchaser while keeping the price within reach of weekend anglers.

 

Ideal Applications

Choose the TM Series if you plan to keep your boat for four years or longer and want to enjoy the benefits of lithium ion without breaking the bank. The batteries are recommended for bass boats, bay boats, flats skiffs, and pontoon house batteries. Check with your favorite boat dealer or order factory direct here.
