Good Afternoon,

I have a 2012 Polaris razor 900 Xp. I currently only have one battery. I have a lot of accessory on my razor and i am wanting to put a second battery on it. How would i hook up two battery’s to keep 12v and hook all of my accessory’s to one battery and if i leave a light on or something it won’t kill my starting battery. I am wanting to keep engine only on main battery and all of my accessory’s on battery 2.
