Im on a tight buget but dont want to buy crap, what have you guys had good luck with? I race every other weekend with my 2 kids. between my shortcourse, my sons slash and my buggy in open and my daughter running it in novice my charger has been getting a workout. Its an older hyperion ac/dc 6061 i think. It has worked great untill yesterday. If I charge at anything over 2 amps it shuts off at 8.1v. I would really prefer something with ac plug in if possible. What are my options? thanks.
