Dual Battery charging

[dubob]

[font "Comic Sans MS"][#800000]That's what I thought; one of the batteries was probably to run an electric trolling motor. Here's the deal on that without knowing which brand/model electric motor you have. Your gas motor puts out 4 amps. Depending on how much thrust your electric motor has, you will draw anywhere between about 5 amps up to 50 amps per hour - depending on the electric motor speed setting. Your charging amps aren't anywhere close to being able to keep up with that much draw. And if you aren't running your gas motor the entire time you are running your electric motor, your batteries will discharge to the point that you will not be able to start your gas motor with the battery(s).[/#800000][/font]

[font "Comic Sans MS"][#800000]Set your second battery up to JUST run the electric trolling motor and charge that battery at home after each fishing trip with either a car battery charger or an onboard 1-bank charger made to be installed on the boat permanently. Leave all the other accessories on your boat hooked up to the cranking battery. The current draw from those other accessories is likely very little and a cranking battery with about a 100 amp hour rating will handle them just fine even if the gas motor isn't being run to troll with as I do with mine. I use my gas trolling motor to push the boat forward in a straight line and set the average trolling speed and then I use the electric trolling motor up front to steer the boat and fine tune the speed to account for wind direction & speed changes.[/#800000][/font]

[font "Comic Sans MS"][#800000]I would not recommend that you need to install one of the Perko switches for your application. Hope this helps with your situation.[/#800000][/font]
