I have another question about my 2009 XTZ. I have a few sets of offroad lights im running plus a radio . When night riding the lights dim obviously with the amount of power draw. I have been thinking about installing a 2nd battery in the underhood storage compartment but am wondering if the alternator can hold up to charging a 2nd battery. I was just going to use another atv battery. Has anyone done this? If so, what type of battery do you use and did you run into any problems?
