Electric trolling motors play a vital operation in fishing. Electric trolling motors help us to operate the boat quietly and reduce the spooking of fish, which will increase your chances of catching fish. And with an electric trolling motor our fishing experience will be different, allowing us to enjoy life better.
For electric trolling motor, it is very important to have an efficient battery, with the progress of society, the development of science and technology, lithium batteries have become a good choice for electric trolling motors, because lithium-ion batteries have a longer lifespan compared with traditional lead-acid batteries, higher efficiency, and do not require us to maintain the battery frequently, in this trend, lithium batteries are more and more widely used. Then how should we choose lithium batteries for electric trolling motors? The specific steps are as follows:

Choose the right size of lithium battery
The battery size of the electric trolling motor is extremely important with the paired boat size, choosing the right lithium-ion battery can help us reduce the weight and space of the battery compartment, which can improve the overall performance of the boat. However, when choosing the ideal size of lithium-ion battery, there are battery size, usage time and other influences. The size of the lithium ion battery depends mainly on the following factors.
1. Thrust of the electric trolling motor
The thrust rating of the electric trolling motor plays an important role in determining the battery capacity. The smaller the thrust, the less power the motor needs and the smaller the battery capacity it requires, and the larger the thrust, the more power the motor needs and the larger the battery capacity it requires and the higher the battery capacity it requires.
2. Length of use
During our fishing, we need to consider the time we use the electric trolling motor, if we use it for a shorter period of time, we don’t need high capacity batteries, if we use the electric trolling motor for a longer period of time, we need to use higher capacity batteries to ensure enough power.
3. Battery Voltage
Electric trolling motors are usually available in 12V and 24V configurations. When choosing a lithium-ion battery, we need to be aware that the battery we choose will be able to provide the required voltage for the electric trolling motor.
4. Battery Weight
We need to consider the weight of the Li-Ion battery, especially if the boat has weight requirements, and the right Li-Ion battery can help reduce the weight of the boat and increase the overall capacity.
Choosing the right lithium battery
Lithium batteries according to raw materials, mainly iron phosphate lithium batteries, lithium polymer batteries and ordinary lithium-ion batteries, according to the core packaging, mainly cylindrical steel shell lithium batteries, soft pack lithium batteries and square aluminum shell lithium batteries these three.
1. Lithium iron phosphate battery
Lithium iron phosphate batteries in terms of performance than the general storage lithium-ion batteries, lithium iron phosphate batteries have a higher energy density, high temperature resistance, with a certain power of high-current discharge capacity. In electric trolling motors are basically improved lithium iron phosphate batteries, in the low temperature performance than nickel-metal hydride batteries slightly better than lithium polymer batteries, but the high temperature performance will be reduced, but this is just suitable for anglers. In terms of installation cost, lithium iron phosphate batteries have higher installation cost and are lighter in weight than ordinary batteries.
2. Lithium Polymer Batteries
Lithium polymer batteries have the advantages of high energy, miniaturization, lightweight and so on, in this advantageous condition lithium polymer batteries can be made into any shape and capacity of the battery, to meet the needs of various products. And lithium polymer battery external packaging using aluminum packaging, if the battery internal problems will immediately through the outside of the packaging performance, even if the problem will not explode, only bulging. But lithium polymer battery energy density and cycle times compared with lithium iron phosphate batteries will decline, and manufacturing expensive.
3. General lithium-ion battery
Ordinary lithium-ion battery is a lithium metal or lithium alloy as the anode material, has the advantages of high energy density and high vibration density, but the safety performance is relatively poor.
Summary
When choosing lithium batteries for electric trolling motors, we need to pay attention to the size of the lithium battery and choose the right lithium battery to make the electric trolling motor work better.
