36v Trolling Motor Battery Wiring Diagram

Trolling motors help anglers navigate through the water silently and efficiently. The perfect trolling motor battery is the backbone of any great fishing trip. To ensure maximum performance and longevity, you need to install it correctly. Here is a comprehensive guide that teaches you how to wire a 36v trolling motor battery.

Benefits of Using a 36v Trolling Motor Battery

Using a 36v trolling motor battery has several benefits. One of the most significant advantages is that it provides more power to your trolling motor to help you maneuver through the water. It is an excellent option for those who fish in larger bodies of water where a weaker battery might not do the job. Additionally, 36v trolling motor batteries are more durable and last longer, giving you peace of mind while out on the water.

However, without proper wiring, you risk damaging the battery or the entire trolling motor.

Materials Needed

Before you dive into wiring the 36v trolling motor battery, it’s crucial to have all the necessary tools and materials. Here is a list of materials you’ll need:

Materials Quantity
36v Trolling Motor Battery 1
6-gauge wires 3
Wire Crimper 1
Wire Cutter 1
Heat Shrink tubings 4
Ring Terminals 4
Battery Terminal Covers 3
Multi-Meter 1

Step-by-Step Guide to Wiring a 36v Trolling Motor Battery

1. Safety First

Before starting the wiring process, it’s essential to put on safety gear like goggles and gloves. Also, ensure that the battery is disconnected from the trolling motor and is placed in an open space with good ventilation.

2. Connecting the Batteries

You need to connect three 12v batteries in series to obtain 36v. Connect the positive terminal of the first battery to the negative terminal of the second battery. Repeat the process between the second and third battery. Using 6-gauge wires, connect the remaining positive and negative terminals to the trolling motor.

3. Install a Circuit Breaker

A circuit breaker is an essential safety device installed between the trolling motor and battery to prevent damage in case of a short or overload. Depending on the motor, it’s recommended that you install a circuit breaker with a capacity of at least 60 amps.

4. Use Ring Terminals

To ensure that the connection between the trolling motor and the battery is secure, use ring terminals with 6-gauge wires. Crimp the wire using a wire crimper and cover the connection using heat shrink tubing. Finally, install battery terminal covers to protect the connection.

5. Test the Connection

After wiring, use a multi-meter to check the voltage across the terminals. The reading should be around 36v. Also, test the circuit breaker by simulating an overload. If the circuit breaker works, it should trip and disconnect the connection between the motor and battery.

Frequently Asked Questions

1. How long does a 36v trolling motor battery last?

A 36v trolling motor battery can last between 4-8 hours, depending on factors like the motor’s thrust and speed and the total weight on the boat.

2. Can I use a charger with a higher voltage to charge my 36v trolling motor battery?

It’s not recommended to use a charger with a higher voltage to charge your 36v trolling motor battery. Doing so can damage the battery, and it might not hold a charge for very long.

3. How often should I charge my 36v trolling motor battery?

It’s advisable to charge your 36v trolling motor battery after every use. Depending on the battery type, it can take up to 8 hours to fully charge.

4. What is the maximum capacity of a circuit breaker for a 36v trolling motor battery?

The maximum capacity of a circuit breaker depends on the motor’s amperage rating. For a 36v trolling motor, it’s recommended to install a circuit breaker with a capacity of at least 60 amps.

5. Can I use two 18v batteries to power my 36v trolling motor?

No, you cannot use two 18v batteries to power a 36v trolling motor. You need to use three 12v batteries connected in series to obtain 36v.

With this comprehensive guide on how to wire a 36v trolling motor battery, you can now enjoy a smooth and seamless fishing experience. Remember to double-check the wiring and test the connection before setting out into the water.
