Wiring Trolling Motor Batteries In Parallel: An Easy-to-Follow Guide
If you’re a boat owner looking to equip your vessel with a trolling motor, then you’ve got a bit of wiring to do. By wiring trolling motor batteries in parallel, you can increase the amount of power and the amount of time your trolling motor will run on the water. With the right steps, it’s not hard to wire up your batteries in parallel. Before you begin, be sure to read the manual and do your research to make sure you understand what you’re doing. This guide will walk you through the steps of wiring two trolling motor batteries in parallel.
Safety First: Preparing for the Job Ahead
Before you start wiring your trolling motor batteries in parallel, it’s important to take some safety precautions. Make sure to wear protective eyewear when working with electrical equipment to protect your eyes from sparks or debris. You should also disconnect the negative battery cable and make sure the wires don’t touch each other as you work. Additionally, it’s a good idea to wear rubber gloves while handling the cables and wiring in order to avoid any shock. Lastly, make sure to follow the specific instructions of your manufacturer to ensure successful wiring.
Gather the Materials Needed
Once you’ve taken the necessary safety precautions, it’s time to gather the materials necessary for wiring your trolling motor batteries in parallel. You’ll need two trolling motor batteries (12-volt, deep cycle batteries are ideal), two marine grade battery cables (at least 8 feet long), one series parallel switch or two separate switches, two battery terminals, and some cable fasteners to secure the wiring. If at all possible, use copper cables and terminals, as these will be more durable than aluminum alternatives.
Understanding Trolling Motor Battery Wiring Basics
Before you start the actual wiring process, it’s important to understand how trolling motor battery wiring works. Trolling motor batteries are wired in parallel to double the capacity of the system. When wiring two batteries in parallel, the positive terminals of both batteries need to be connected together, and the negative terminals of both batteries need to be connected together. This ensures that the voltage of the system remains the same, but the capacity doubles.
Step by Step Instructions for Wiring Batteries in Parallel
After you’ve gathered all of your materials, you can begin the wiring process.
- Start by connecting the positive terminal of one battery to the positive terminal of the other battery. Use the appropriate size cable and secure it with a cable fastener.
- Next, connect the negative terminals of the two batteries in the same way, using a separate cable.
- If you’re using a series parallel switch, connect the cable from the negative terminal of the first battery to the negative terminal of the second battery to the switch.
- If you’re using two separate switches, connect the negative terminal of one battery to one switch and the negative terminal of the other battery to the other switch.
- Then, connect the positive terminals of the two batteries to the appropriate terminals on the switches.
- Finally, once all the cables are connected, secure them with cable fasteners and turn on the switches. Your trolling motor batteries should now be wired in parallel.
Conclusion
By following the steps outlined above, you can easily wire two trolling motor batteries in parallel to increase the capacity of your system. Make sure to take the necessary safety precautions and read the manufacturer’s instructions before beginning the wiring process. With the right preparation and knowledge, you can easily wire your trolling motor batteries in parallel and enjoy more power and longer running times out on the water.
