hello all im a noob here. but this is the plan i came up for isolated batterys in my truck and running my stereo and amps off of a second battery, i often listen to music with my truck off the only thing else that i could think of was putting a relay on the switched power for the stereo because i dont know if the stereo could possibly create a bridge if you will between the two battery that could potentially fry the stereo. i figure that because my understanding of the isolator is that it will charge the primary battery and then the second battery and the primary if its full. do you guys think that this will work?
