Hello All! I am kinda new to the forum. I plan on running a 300 Watt stereo system in my razor and I was planning on hookin it up with a better battery. I want to run a smart battery seperator from Black Rhino and an oddessy battery. Would it be a bad idea to run my stereo and my two 4" HIDs off of the odessy and continue to use the stock battery as a cranking battery? I heard that it is a bad idea to mix batterys.
