Lithium Trolling Motor Batteries Review

Many fishermen are quite familiar with boat batteries. They may be of different types like gel, flooded, lithium-ion, etc. In this article, I will review the top 5 drop-in lithium batteries that are available in the market. But before that, let’s learn a few things about lithium batteries.

Overview

Drop-in lithium-ion batteries don’t require any specific lithium batteries charger. They can be charged with gel or AGM battery chargers because the BMS controls the charging. Lithium batteries also have many advantages over other trolling motor batteries. One of the biggest advantages is its longer-lasting power.

A regular 36-volt trolling motor runs from three 12-volt marine batteries in a series to achieve 36 volts. Three 100 Amp Hour (AH) lithium batteries in a series will provide this power. You may say, what’s so special about a lithium-ion battery then? The answer is very simple.

By far the biggest advantage to a lithium-ion battery is charge cycle life. A standard lithium-ion battery with a BMS can be cycled 2000 times, think about that, 2000 full day fishing trips. A high-quality AGM lead-acid battery can only cycle 500 times to 50% power, on average.  

Next, other marine batteries lose voltage when they are drained. When a battery reaches a 50% charge, they can’t produce enough power to run the trolling motor, and the motor stops. A lithium battery, on the other hand, doesn’t lose any voltage while discharging. This is why they can provide twice as much power as a regular battery for a longer period of time.

Other advantages of lithium batteries are that they are equipped with overcharge and deep discharge protection. This ensures that your batteries can be used for a longer period of time than a comparable lead-acid battery. They also weigh about half that of conventional lead-acid trolling motor batteries.

The final advantage of note is wire sizing. Because the voltage stays in a more consistent range then Lead-acid batteries you should not need to oversize any of your wires, saving you money. Technically speaking a battery with a BMS also has a short circuit disconnect built-in so you would not need a fuse or breaker, but it is still the best practice and ABYC wiring code.

After reading about so many advantages, you may think that there are no drawbacks to lithium batteries but I am sorry to say that you are wrong. The biggest and foremost disadvantage of lithium batteries is its price. Even the cheapest ones may be a bit too much for your budget.

So, is it worth putting the money upfront for lithium batteries? Well, that depends on your needs. If you want a long-lasting battery that is super durable, then I must say that lithium batteries are best for your needs.

Now that we have learned about lithium batteries, let’s look at the top 5 drop-in Lithium Trolling Motor Batteries Reviewed, on the market today. So, without any further delay, let’s get started.
