Battery Hook-up

[silvercreek]

I have a Bass Tracker Pro-Crappie (2002) with two batteries, starting and trolling. My question is which battery should I hook the two Humminbird fishfinders too? Also any one have any experience with the Duracell AGM marine battery from Sams club. Thanks

Hook your electronics to the starting battery. Hooking them up to the trolling motor battery can cause interference.

Your trolling motor battery should be for that, the trolling motor. All other electronic etc should be ran off the starting/cranking battery. The starting battery should remain charged up and the electronics should function fine, on the other hand the trolling motor battery will get drawn down to low voltages where electronics will not function correctly, this is why trolling motor batteries are deep cycle type, they can survive being sucked down and recharged numerous times.

Thanks for the help, I have a little work to do.
