Many customers have questions on the subject of wiring trolling motors and marine electronics. This step-by-step guide aims to simplify the process. Marine Battery Wiring Author: Wes Wiedmaier Many customers have questions on the subject of wiring trolling motors and marine electronics. The battery system on most boats can be broken down into two parts: a starter battery and a trolling-motor battery system. The volt starter cranking battery delivers cranking power to the outboard motor. It can also be used as the power source for onboard electronics, such as depth finders.
Batteries can be wired in an electrical circuit so that their voltages add together. This is an especially common problem with marine equipment, which frequently uses 24 volts, while many batteries are only 12 volts. With enough patience and the careful following of instructions, 12 volt batteries can provide 24 volts of battery of energy in no time. It's important to make sure you that your work space in clean and clear and free of any flammable materials like alcohol, gasoline, or other simple household items like flammable cleaning solutions as well as items of clothing, towels, and blankets that could easily catch fire if near a flame. You should also be careful to be free of any standing or puddled water while working. It's very easy to be electrocuted when working with batteries and voltage near and around water.
One of the best upgrades to small fishing boats is replacing the volt trolling motor with a more powerful volt model. In addition to producing more thrust, this upgrade will also let you spend more time on the water, as the combination of two trolling motor batteries will last much longer before charging is required. Determine a suitable location for the battery tray for the added battery.
Learn how to connect two 12 volt batteries to make one 24 volt battery unit. This is a common application needed to supply power to a trolling motor requiring 24 volts. Some larger trolling motors will require 36 volts by connecting together 3 deep cycle 12 volt batteries in Series. Similar to Flashlight Batteries. Connecting 2 or more 12 volt deep cycle batteries together need not be intimidating.
