Our famous 2nd Battery Kit includes a UTV Stereo Platinum Series Performance AGM Deep Cycle Battery. The Isolated system lets you drain the 2nd battery while the key is off preserving your stock battery's charge for starting. Once the car is running, both batteries are connected and being charged. We make it easy and reliable! Now you can sit with your lights on and music playing all worry free.
