need help w/ extra battery
Hey there I was looking for some help here
I have a stock battery in my car which I want to upgrade to a newer larger battery. I wish to keep the stock battery in the car and connect it to the newer battery.
I want to have both batteries connected so that If i were to drain one somehow the car would always crank.
Also, I wish to use the stock battery as a capacitor for my stereo system, and also for a tank circuit so that when I crank the car the carputer stays on.
Have done a quick search, can anyone help me out here? Need to know: can I have the battery do all these things and also how should I wire it?
