Features of Delong Lifepo4 Battery

LightWeight Lithium Battery For Your Trolling Motor

Compared to bulky traditional batteries, lightweight lithium batteries are more convenient to carry and replace. This is especially beneficial when you need to travel to distant wilderness locations and fishing spots, as it can save you a lot of physical effort. 

Lithium batteries have a higher energy density, which means they can store more energy for the same volume or weight. Using lithium batteries for watercraft such as trolling motors, fishing boats, kayaks, and tour boats not only saves space but also contributes to faster movement of the vessel, resulting in a better fishing experience.

How To Choose The Right Battery System For Your Trolling Motor?


When selecting a battery for your trolling motor, you need to consider the thrust, usage time, size and weight of the boat, as well as the conditions of use.

Generally speaking, the greater the thrust of the trolling motor, the higher the voltage required for the battery.

The longer the boat is in operation, the larger the capacity of the battery needed.

Larger or heavier boats require more thrust, which in turn requires a larger capacity battery.

Additionally, factors such as water currents and wind speed will also affect the choice of battery.

For a 12V system:

If the motor’s thrust is between 30lbs to 55lbs, you can opt for a 12V lithium battery with a capacity ranging from 50Ah to 100Ah, depending on the anticipated usage time.

For a 24V system:

If the motor’s thrust is between 70lbs to 90lbs, it is recommended to choose either two 12V lithium batteries connected in series or one specialized 24V lithium battery, with a recommended capacity of 100Ah to 200Ah.

For a 36V system:

If the motor’s thrust exceeds 90lbs, you will need three 12V lithium batteries connected in series or one specialized 36V lithium battery, and the capacity will likely need to be over 200Ah.

The battery is very lightweight but provides reliable power for my kayak.


The battery itself can self-protect and will cut off on its own when overcharged, which is great.


The size and weight are perfect for my canoe, and it can run all day, which is an amazing experience.


The battery is good, and after thorough testing and use, I will decide whether to purchase another two.


The company responds quickly, which I really like. I bought three batteries to connect in series for a 36V trolling motor. The batteries can run for a long time and also charge quickly. So far, they are highly recommendable.


FAQ About Trolling Motor Battery

This 12V 100Ah lithium trolling motor battery is a deep cycle storage battery and is not suitable for use as a starting battery.

Here are 3 ways you can charge your lithium trolling motor battery:
• 14.6V Lithium iron phosphate 4-string Charger
• Photovoltaic solar panels with MPPT
• Inverter (built-in AC to DC)

In theory, there is no limit to the number of lithium batteries that can be connected in parallel. However, in practice, connecting too many batteries in parallel can lead to faster degradation of the batteries. Therefore, Delong recommends adhering to industry standards, which is to connect no more than four batteries in parallel.
