I ran it for months on 5s in its stock form. It takes it easily. I know that Jim from Tekin even said it would probably take 6s. It has 30v components inside. But I personally havent tested it. With Arturs mod to it its now limited to 5s becasue he used a 27v component on it. But 5s is plenty for me. In stock form it ran my buggy with 5s and a Hacker 10xl geared for 38-40 mph or so without even breaking a sweat on the track.
