At the same time, you are warned Marine Battery that if you run your motor at high speed (over 85%) for a long time, it could damage your motor. Many lithium batteries are rated at 1c, which means the maximum discharge current is equal to its capacity. For example, a 60Ah lithium battery can be discharged at 60 Amps. A lithium battery can keep your trolling motor at the same speed for almost twice as long as lead-acid batteries of the same rated capacity. Today, we discuss the pros and cons of having lithium batteries on board and what you should know before buying one. We also review popular LiFePO4 batteries used with trolling motors today.

We recommend using at least a 100 ampere-hour rating, group 27 rating, and 175 minutes of RC(Reserve Capacity). Here is a table for you to pick the right trolling motor battery according to the size and the voltage or Amp/ hour. Note that the Optima isn’t rated by amp hours, as the spiral cell technology involved doesn’t carry over to this conversion method. Rest assured, the Optima will outlast any regular plated battery in its own class.

Product Description

People say that the battery is great in hot weather and can go a long time between charges. Reviewers claim to get as long as six years out of their Optima Batteries. People also say that these batteries are great for storage because they have a low self-discharge rate, so even after long periods of non-use, they still keep a charge. If you do not have the right battery, you may not have enough power to turn the motor over, and you could find yourself stuck out on the water. Charge your batteries immediately after use, and keep them plugged into the appropriate charger until they are 100 percent charged.

I can monitor my battery’s status in real-time and manage its discharge with ease. The low-temp cut-off protection is another standout, ensuring the battery performs safely in temperatures as low as -20℃. Whether I’m running a trolling motor in the middle of a lake or using it for off-grid power, it’s reassuring to know the battery is protected in extreme conditions.

What Other Battery Types Can I Use For My Trolling Motor?

I ran the Millertech Dual Purpose 12V 135Ah lithium battery for several trips without charging and it was still more than 50% charged. Match battery voltage to your motor’s requirements—using insufficient voltage reduces thrust, while excessive voltage risks equipment damage. Lithium batteries maintain stable voltage output throughout discharge, unlike lead-acid batteries that lose efficiency as they deplete.
