Lithium Ion Trolling Motor Battery: Introduction, Working, and Charger

Those who have fishing as their hobby must know the importance of trolling motor for their fishing expedition. After all, the trolling motor plays a big role in getting you closer to the fish that you want.

Since the trolling motor is important, fishers need to handle the trolling motor with care. One of the ways to do it is by giving proper care to the trolling motor, and one of them is by giving the trolling motor proper battery. One of the batteries you can use is lithium ion battery. Here, we will help you understand everything you need to know about lithium ion trolling motor batteries.

Can you use a lithium ion battery for your trolling motor?

Yes, you can actually use lithium ion battery for your trolling motor! In fact, any battery with 12-volt battery can work (make sure it’s also a marine battery, though). Lithium ion battery suits the requirement of the battery needed to make a trolling motor run.

Before you pick your battery, it’s important for you to find out what kind of trolling motor you need. Here are some things you can do to decide the trolling motor you need.

1. Decide how many voltages you need for your trolling motor

The voltage matters, as it decides how much power you will get from it. The bigger the voltage is, the more thrust the trolling motor provides. If you want something that’s simple and also inexpensive, you can opt for the 12-volt trolling motor.

2. Know the amp draw for your vehicle

Knowing the amp draw will help you to determine the battery you need. After all, you need to make sure that the amp draw you have cannot be less than the battery’s discharge rate. Doing so will never be lacking in battery power since your trolling motor won’t demand more energy.

3. Get a battery with continuous discharge

Make sure the continuous discharge of the battery is bigger than what you need for your trolling motor. For example, a 12-volt trolling motor can use 23 Ah batteries, but bigger trolling motors and will hold a heavier burden will need more than 23 Ah batteries.

4. Find out how long you want the battery to last

Yes, the amount of time you want the trolling motor to run does matter. The more time you want it to run, the bigger the volt and capacity should be. If not, there might be a chance where your trolling motor dies in the middle of your fishing expedition.

If you need some examples of lithium ion batteries for you, here are some whose specs you can check out:

1. VMAX V35-857 12 Volt 35AH AGM Deep Cycle Group U1 Battery

This is an example of a battery that has no vibration trouble. The 12 volt battery can be recharged quickly too, so you don’t have to take a long time to recharge it. The battery lasts for four to nine hours, depending on the time you will use the motor.

Some batteries need to be used often. If left alone, those batteries will lose their charge. Unfortunately, VMAX V35-857 is one of those batteries.

2. Weize Powermall 12V 75AH Deep Cycle Battery

Weize is another 12 volt battery, like VMAX, but it is a little bit bigger. What makes the battery great is the powerful energy it gives. Moreover, the battery can also be used for other things such as scooter, golf carts, solar, and so on. So if you want a lithium ion battery that can be used for many things, you should find a batter similar to this one.

3. Lithium Ion Deep Cycle Battery – Ionic 12V9-EP – 12V 9Ah – LiFePO4 with BMS

Lithium Ion Deep Cycle Battery is probably the ultimate lithium ion battery there is. It is at least 70% lighter compared to other batteries, as it weights below 3 pounds. Moreover, it has an amazing cycle that can last up to 5,000 life cycles. It is also small, making it pretty compact and suitable for most motors.

The battery packs 12-volt energy, so it is suitable for standard trolling motors.

How does a lithium ion trolling motor battery work?

They work like the usual battery, giving power when the trolling motor needs it. However, what makes it different is how the energy is given to the trolling motor. Traditional batteries, if used on trolling motors, will typically lose power as the trolling motor is on. It results in the trolling motor gradually losing thrust and trolling motor.

This is why you need a continuous discharge, as it can give the trolling motor full thrust nonstop and only dies out when the energy is drained at almost one hundred percent.

To make it even better, lithium ion batteries can be charged. So, there’s no need for you to buy batteries again and again. All you need to do is plug the charger and let the battery refills its energy until it’s at one hundred percent. Pretty easy, isn’t it?

Do you need a lithium ion trolling motor battery charger?

Since lithium ion can be recharged, yes! You do need battery charger for your lithium ion batteries. Without them, there is no way you can refill the energy that was lost and taken by the trolling motor. And no, you cannot gain energy by exposing the battery to the sun. use a charger and only charger to get the energy for your lithium ion battery. Once you have your charger, you can use it again for your trolling motor!

Using lithium ion is not so bad, isn’t it? It can give continuous power without losing thrust. Moreover, you can always recharge it whenever you want. Of course, you should also note that not all trolling motors can use lithium-ion, so it’s best to check your trolling motor first. If your motor is suitable, then go ahead and use it. If lithium ion battery is already the perfect choice for your trolling motor, then why not?
