I think it depends on the battery (style & capacity). I've been running my 80w panel with no problems wired directly to the series pair of 6v 225ah floodies in the car. But when I ran it to a parallel pair of 12v 7ah SLA's, the voltage rose very quickly and they started gassing. If I'd left them hooked up, they would have fried in no time!
