What Is Trolling Motor Battery?
Trolling motor battery are used to power the trolling boat. For marine batteries, the engine must be started and then provide enough power to maintain the motors and equipment connected to the boat.
Trolling motor batteries are typically 12 V battery, 24 V battery, or 36 V battery, depending on your trolling motor spec.
How To Choice The Trolling Motor Battery?
When choosing a trolling motor battery, factors such as battery type, battery voltage, battery capacity,(amp-hour rating). Also we should also consider the battery dimension.
A trolling motor battery is a source of power that can provide a constant source of power to your boat. If the trolling motor battery is used for small travel, or for fishing purposes, a high power battery is required in this case.
You should always be very careful when choosing the right motor battery for your boat, always choosing the right type of battery for the right type of boat. There are many different types of trolling motor batteries available on the market, such as lithium-ion, deep cycle, and absorbent glass mat batteries. Generally speaking, the most cost-effective is the lithium-ion battery
There are usually three types of batteries available on the market. Lead-acid, AGM battery and lithium batteries.
Ordinary Lead Acid Battery
Lead-acid batteries are one of the most common types of batteries used with trolling motors. They are an affordable option with a lower initial cost and can also handle the everyday use of a trolling motor. They usually last about 2-3 years and usually require checking your battery to make sure there is enough water in the battery. If you are running low on water, add distilled water to prevent damage to the battery.
AGM battery stands for Absorbent Glass Mat. Unlike lead-acid wet batteries, these types of batteries are completely sealed. AGM batteries are more expensive than regular lead-acid batteries, but do not require any maintenance. AGM batteries usually last 3-4 years, which is a little longer than normal lead-acid batteries.
Compared with lead-acid batteries, lithium batteries can last 10 times longer while being smaller and lighter. As well as supporting 1-2 hours of fast charging time to ensure you get the most out of your adventure.
Some other notable advantages of lithium trolling motor batteries include:
- Longer Lifespan
- Light weight
- temperature resistance
- 1-2 hours fast charging
- Maintenance free
- Lower cost per cycle
- Safe and & Non-hazardous

Most of motor batteries usually are 12 volts. we recommend you to check the power system to determine if more voltage is required. Also some power systems require 24 or 36 volts.
The capacity determine how long your battery will last.
A higher amount of amp-hours will provide more energy to your trolling motor, and your trolling motor will last longer. This is one of the most important specifications that we need consider.
We recommended to use at least 100 amp hours in trolling motors to ensure your battery won’t fail. But higher amounts, for example, a 120 or 150 amp hour battery will last longer. It depends on what type of needs you have to determine what amp-hour would be best suited for you.
Usually, the battery dimension depends on the size of your battery space size. Please try to choose a battery that matche with your battery space size. if the battery dimension is too large to fit in the battery compartment, and the battery is too small will shorten the battery using time.
How Long Do Trolling Motor Batteries Last?
Lithium trolling motor batteries usually last for 4,000 times cycles, while lead acid batteries for 1,000 to 1,500 times cycles.
Also the lithium batteries are lower maintenance than lead acid batteries. Lead acid batteries need to be kept topped up with water to protect the lead plates inside them. And they will become damaged if they are allowed to get too hot or too cold. However, the lithium battery are sealed and maintenance free.
How Does Trolling Motor Battery Work?
While the battery is discharging and providing an electric current, the anode releases lithium ions to the cathode, generating a flow of electrons from one side to the other.
When plugging in the device, the opposite happens: Lithium ions are released by the cathode and received by the anode.
This process creates an electrical current that powers the electronic devices.

How To Charge The Trolling Motor Battery?
The actual charging process is actually relatively simple. For lithium battery chargers, the process is pretty much the same.
1.Step one, First unplugging your motor. Check the battery for leaks or damage, and make sure the battery terminals are clean.
1.Step two, Connect the charger to the battery. Positive to positive, negative to negative.
3.Step three, Connect the charger to the power source. Once connected, turn it on.
4.Step four, Monitor progress. When charging is complete, unplug it.

How Long Does It Take To Charge Your Trolling Motor Battery?
One of our most frequently asked questions is “how long does it take to charge your trolling motor batteries?”
Our experts note charging time depends on the specific charger in your system. Lithium-ion batteries have low internal resistance, so they will take all the current delivered from the current charge cycle. For example, if you have a 50-amp charger and a single 100-amp hour battery, divide the 100 amps by 50 amps to come up with a 2-hour charging time.
Another example is if you had five 100Ah (amp-hour) batteries for a total of 500Ah and a 100-amp charger. It would take about 5 hours of charging from empty to 100 percent while factoring in enough time to balance the charging cycle.
We don’t recommend you exceed this charge rate as it can lead to a shortened battery cycle life. In an emergency, the battery can be charged at a quicker rate if needed. But we don’t recommend you make a habit of emergency charging your battery.
