What is a trolling boat motor?

A trolling boat motor is a type of electric drive device used on a trolling boat. Often referred to as a Trolling Motor or Trolling Boat Motor, this device is designed to be mounted on the stern or outboard side of a boat to provide additional power and boat control.

What are the factors in choosing a battery for a trolling boat motor?
When choosing a battery for a trolling boat motor, there are some key factors to consider to ensure that the battery will meet the boat's power requirements and perform well in use. Here are some important factors to consider:

Battery type: batterie with different characteristic types offer different performances. Common battery types include lead-acid, AGM, polymer, and lithium-ion. Lithium-ion batteries are typically lighter and more durable but may cost more.

Capacity: Battery capacity indicates the amount of electrical energy a battery can store. Selecting a battery with the proper capacity depends on the power requirements and usage time of the trolling motor. Increased capacity batteries can provide longer drive times.

Voltage: Trolling motors are usually designed  with a specific voltage range. Please Make sure the voltage of the selected battery meets the specifications of the trolling motor.

Cycle Life: Cycle life is an indicator of how many times a battery can be charged and discharged and still maintain performance. Consider the cycle life of the battery, especially if gapped charging and discharging is required at all.

Charge Time: Know how long it takes to charge your battery. Some battery types can be recharged more quickly, which may be important in situations where a quick charge is needed in a short period.

Environment: Consider how the battery performs in different environmental conditions, such as temperature ranges. Some batteries may suffer from performance in extreme temperatures.


What are common trolling boat motor batteries?
Types of batteries for trolling boats typically include:

Lead-acid batteries: lead-acid batteries are a common and economical choice, and are divided into wet-cell and AGM (absorbed glass fiber) batteries. They are relatively inexpensive, but have an increased weight and have some cycle life.

Lead Acid Wet Battery: Lead acid wet batteries consist of three parts: Bluetooth, the drastic, and static fluid.The spinning fluid is usually made of lead oxide and eventually lead sponge (Pb). The resting fluid is an aqueous solution of dilute sulfuric acid, which contains sulfuric acid.
Unlike AGM batteries (Absorbed Glass Fiber Batteries), lead-acid wet batteries have a continuous fluid, an aqueous sulfuric acid solution. This allows the continuous fluid to flow freely inside the battery, which encourages the chemical reactions in the battery.

AGM Battery: Fully known as an Absorbent Glass Mat (AGM) battery, it is a type of lead-acid battery. Compared to traditional lead-acid wet cells, AGM batteries use a special Absorbent Glass Mat structure that holds the dynamic fluid between the glass fibers, rather than allowing the static fluid to flow freely. With a sealed structure, they do not leak acid and are suitable for use in well-ventilated cabins. They are closer together and have better cyclic wear.

LITHIUM-ION BATTERIES: Lithium-ion batteries are becoming increasingly popular in many applications because of their high energy density, light weight and long life. They are also capable of providing a stable power output for applications that require continuous use. However, lithium-ion batteries are typically more expensive than lead-acid batteries.

There are great benefits to upgrading your trolling boat motor battery to a Gecenpower LiFePO4 battery.

1. Long cycle life: Gecenpower LiFePO4 batteries typically have a longer cycle life. They can withstand more charge/discharge cycles and have a better lifespan than traditional lead-acid batteries, which makes them more reliable for long-term use.

2. Lightweight design: Gecenpower LiFePO4 batteries appear to be lighter compared to lead acid batteries, which means that the efficiency and speed of the boat can be improved while saving weight.

3. Safety: Gecenpower LiFePO4 batteries are relatively safe, and they have a lower risk of thermal runaway compared to other lithium-ion battery types, such as lithium cobalt-acid batteries. This makes them more suitable for use in specific environments.

4. No maintenance required: Compared to traditional lead-acid batteries, Gecenpowe LiFePO4 batteries do not require routine maintenance, such as stopping fluid checks and additions. They are usually closed and require supplemental maintenance.



What is the typical power of a trolling boat motor?

The power of a trolling boat motor is usually expressed in "pounds of thrust" (lbs of thrust) rather than directly in "power" (horsepower). Trolling boat motors are available in a wide range of thrust capacities, usually from 30 to 150 pounds. Generally speaking, a thrust between 55 pounds and 80 pounds is a more common choice for trolling boat motors. Powerful motors usually provide enough power to propel a small to medium-sized trolling boat through lakes, rivers , or oceans.

Warm tips: While choosing Gecenpower lithium iron phosphate batteries, you can refer to the following data in making your selection.


1. Between 30 and 55 pounds, we recommend you use a 12V 100Ah lithium iron phosphate battery.


2. 55-80 lbs, we recommend you to use a 12V 200Ah lithium iron phosphate battery.
