How to Hook Up Trolling Motor Batteries

Trolling motors are an essential piece of equipment for anglers who enjoy fishing on boats. These motors are powered by batteries, which need to be properly hooked up to ensure smooth operation on the water. If you’re new to using a trolling motor or need a refresher on how to hook up the batteries, we’ve got you covered. In this article, we will guide you through the process of correctly connecting your trolling motor batteries.

Step 1: Gather the necessary equipment
Before you start connecting the batteries, make sure you have the required equipment. You will need a set of batteries (usually 12V), battery cables, a battery box, a battery switch, and a multimeter.

Step 2: Position the batteries
Place the batteries in the battery box, ensuring that they are securely positioned to prevent any movement during boat operation.

Step 3: Connect the batteries in series
Take one battery cable and connect the positive terminal (+) of the first battery to the negative terminal (-) of the second battery. This will create a series connection, effectively doubling the voltage. Repeat the process for the remaining two terminals, connecting the negative terminal of the first battery to the positive terminal of the second battery.

Step 4: Connect the trolling motor
Attach the positive cable from the trolling motor to the positive terminal of the first battery. Connect the negative cable from the trolling motor to the negative terminal of the second battery.

Step 5: Install the battery switch
To control the power supply to the trolling motor, install a battery switch between the positive terminal of the first battery and the positive cable from the trolling motor. This switch will allow you to easily turn the motor on and off as needed.
