I have 3 batteries in my boat. One for cranking that is rated @ 750CCA. The other two are used for the 24V trolling motor. Both are 29 series batteries rated at 875CA.

My question is which battery should I hook the accessories up to? IE: Nav lights, fish finders, etc

Thanks

Chris

Run all of your accessories off the cranking battery. It gets recharged whenever the big motor is running. In addition, running the depth finders off the TM battery can result in electrical interference from the TM.

Everything except the TM to the cranking battery!
