Hey guys, Just wondering... We do love to hit the Raider Games (I know we are suckers for punishment) and I thought it would be epic to use the Tesla for a pre game Tail Gate party. Can you sit with the Radio on, back hatch open, etc. for a couple of hours without running down the battery? Does the Radio use the same Battery Pack for it's power or do these have some type of standard 12 volt battery installed for the 12 volt car functions such as the radio? Any thoughts on if it would harm the battery to do such things on a regular basis?
