What is a trolling motor?
A Trolling motor could be a self-contained unit that is battery supercharged and controlled via hand, foot lever, or remote furthermore includes a propellor. It is set on the bow or stern and used for moving a watercraft through the water methodically and quietly. Moreover, it helps to avoid spooking the fish.
What Is A Trolling Motor Used For?
The trolling motor permits a ship to remain in one spot once fighting against current or wind while not deploying a physical anchor. It additionally offers maneuverability, mobility, and fishing throughout the day.
This motor is the proper tool to move and maneuver a ship when one doesn’t wish to start a loud outboard engine. Trolling motors additionally use for linking up with fish-finder natural philosophy, and it will keep in one spot supported GPS location.
What Are The Types Of Batteries For Trolling Motor?
We can divide the Trolling motor battery type into two sorts, such as:
- Cranking or Starter Boat Batteries
- Deep Cycle Batteries
Cranking or Starting boat batteries
This starter battery is designed to start your main engine and discharge an outsized current for short bursts. Starter batteries can’t perform below 50% energy level. The deep cycle marine battery comes with a cranking Amps (CA) rating found on a battery’s label measures a battery’s beginning power. Also, don’t forget about cold-cranking amps so that you don’t get into trouble in the winter.
Deep Cycle Batteries
Deep cycle batteries are associate energy storage units during which a chemical change happens that develops voltage and ends up in electricity. These batteries’ style is to cycle (discharge and recharge) repeatedly.
There are different kinds of deep cycle batteries, such as:
AGM batteries (Absorbed Glass Mat)
AGM stands for Absorbed Glass Mat and also are observed as a Valve-Regulated lead-acid battery (VRLA) or Sealed Lead-Acid (SLA) battery. AGM batteries use electrolyte-absorbed mats. This permits oxygen to recombine with hydrogen gas to replenish the battery’s water content and alleviate refilling requirements. AGM batteries are maintenance-free that can also serve as dual-purpose batteries.
Gel batteries are full of a liquid solution gelled with silicates before the battery is sealed. They’re maintenance-free, sealed, low-temperature tolerant, shock/vibration resistant and have long cycle life.
Wet-Cell Boat Batteries
The standard lead-acid batteries we tend to all are familiar with the wet-cell or “flooded-cell” batteries. Every wet-cell battery contains a liquid mixture of sulfuric acid and distilled water. Lead Acid Wet-Cell batteries are the highest standard and cheap option for trolling motors.
What Size Battery For Trolling Motor: The Ultimate Guide
We have already mentioned the kinds of batteries. Now, we’ll look for the boat battery size. As a result of the battery’s incorrect size, you’d be out of power to run your trolling motor that interprets to be stranded, and it reduces the life span of the battery.
You initially have to be compelled to check out the space you’ve got obtainable for your trolling motor batteries in your boat. If you are attempting to put a trolling motor rated at 105 pounds of thrust on the back of your canoe or small boat, you may need to use three batteries, and you need to make sure of enough space for three batteries, yourself, and all your gear.
Now you ought to contemplate what quantity you’re going to use the trolling motor or what’s the capability of your trolling motor battery? Therefore, when you are looking for these queries, you should calculate the battery capacity of your trolling motor.
Two factors you’ll need to consider
It’s the measure of the quantity of charge the battery will hold. Different motors draw different amounts of current depending on the scale and, therefore, the engines’ speed of rotation.
An electric battery with a 115 Amp Hour Rating can beat a 100 Amp-hour rated battery in terms of endurance. If a trolling motor runs at low speed and pulls solely four amps, the battery will last up to (100Amp hour rating/4 Amps) = 25 Hours.
However, if it is drawing 40 amps, then the battery would last for 2.5 hours. So, the larger the score, the longer it’ll power your battery to operate at a particular speed.
Ampere draws of the motor
Another crucial issue is that the ampere draw of the motor. The measure of the ampere drawn by the engine per watts from the battery provided the constant speed.
Now having these two pieces of information, all you need is to divide the ampere-hour rating by the motor amperage draw. You’ll get to understand the calculable battery lifetime of the battery of your trolling motor.
For example, let’s assume the battery voltage is 12V.
If I would like to understand what size battery for a 36lb trolling motor is employed and its lifespan? The solution is we can use a 360W battery, and its Amp-hour rating is 29AH.
The Amp draws going to be = (360/the voltage of battery 12V) = 30 Amps.
So, the life span= (Amp-hour rating/Amp draws) = (29AH/30Amps) = 0.96Hour.
We will also contemplate what size battery for a 55lb trolling motor is needed together with its runtime?
Its battery requires 624W, and the amp hour rating is 52AH.
Amps Draw =(624W/12V) = 52 Amps.
So, Runtime = (52AH/52Amps) = 1 Hour.
From the above discussion, you may have learned how you can calculate the capacity of your trolling battery. So, whenever you buy a battery for your marine trolling motor, you should calculate the amps rating and the runtime of your trolling battery. It will help you to choose the best battery for your trolling motor.
