24 Volt Trolling Motor Battery Wiring Diagram

Are you planning to buy a 24-volt trolling motor battery? If yes, you must know that wiring it correctly is just as essential as getting the right model for your boat. A properly wired battery ensures that your trolling motor runs efficiently, and your boat glides smoothly on the water.

The Importance of Proper Wiring

Before jumping onto the wiring diagram, let’s understand why it is so essential to wire your 24-volt trolling motor battery correctly. Firstly, incorrect wiring can damage the battery, the motor, and even pose a threat to you and the boat’s safety. Secondly, it ensures that the motor runs with maximum efficiency, which means longer runtime and better performance. Thirdly, proper wiring eliminates the chances of voltage drops, which can cause the motor to run slower and reduce the battery’s overall lifespan.

Wiring Diagram

Wiring a 24-volt trolling motor battery can be done in two ways- series and parallel connections. In this article, we will discuss both in detail.

Series Connection

In a series connection, the positive terminal of one battery is connected to the negative terminal of the other. This connection doubles the voltage and keeps the overall capacity of the batteries constant. Here’s a step-by-step guide on how to wire two 12V batteries in a series connection:

Battery 1 Battery 2
Positive Terminal Negative Terminal
Negative Terminal Positive Terminal

Once the batteries are connected, you will have 24 volts output. Connect the positive and negative wires from the motor to the positive and negative terminals of the series connection, respectively.

Parallel Connection

In a parallel connection, the positive terminals of both batteries are connected together, and the negative terminals are also connected together. This connection keeps the voltage constant and doubles the capacity of the batteries. Here’s how to wire the batteries:

Battery 1 Battery 2
Positive Terminal Positive Terminal
Negative Terminal Negative Terminal

Once the batteries are connected, you will have 24 volts output. Connect the positive and negative wires from the motor to the positive and negative terminals of either battery.

FAQs

Q. Can I use two different battery models for a 24-volt trolling motor?

Ans. It is not recommended to use two different battery models, as it can potentially damage one of the batteries or the motor.

Q. How can I ensure that my trolling motor runs efficiently?

Ans. In addition to proper wiring, make sure to check the motor’s thrust and match it with your boat’s weight. Also, keep the battery charged and maintained.

Q. What happens if I wire the batteries incorrectly?

Ans. Incorrect wiring can damage the batteries, motor, and even cause a fire hazard. It is crucial to follow the correct wiring diagram.

Q. Can I switch between series and parallel connections?

Ans. Yes, you can switch between series and parallel connections, but make sure to follow the correct wiring diagram when doing so.

Q. How long will my trolling motor battery last on a full charge?

Ans. The runtime of a trolling motor battery depends on several factors, such as the motor’s thrust, the weight of the boat, and the battery’s capacity. On average, a 24-volt battery can last for 4-6 hours on a full charge.

Proper wiring is crucial for the smooth functioning of your trolling motor. Follow the wiring diagram mentioned above, and make sure to take all safety precautions while handling batteries.
