My son has a 60 ft drag race this weekend. We have a F150 with super 6 battery (also have a Jeep Wrangler with a super 6). We made a 12 volt battery up grade on it. Wow what a difference. The class rules only allow battery up grades. The . 24v fisher price battery is the most anyone is allowed to run. I'm wondering how much I can run threw the stock 6v motors before they fail?
