I'm pretty sure I'm going to order a sure power 1314. The way I understand it is, the starting batt gets the alt hooked up to it, and gets hooked to the the #1 position on the 1314. Then the stereo batts get hooked to the #2 position and only get charged after the 1st batt is full.
One of the cool things about the 1314 is that if the start batt fails, the 1314 will connect and let the stereo batts start the boat. Thats the part that I have a question about.
My boat came with 2 batts and an isolator. I was thinking of using the isolator to keep the 2 stereo batts seperated. I could use 1 for each amp. The only problem with setting it up this way is if the 1314 ever let the stereo batts start the boat. It would pull a ton of current through the isolator all at once.
Do I even need to isolate the the stereo batteries from each other? It would be a lot easier to wire if I didn't.
