I am getting ready to get back into the hobby after a many year layoff for family and kids. I am needing some advice on a good charger. I know I want the charger to be AC/DC and can handle a 7 cell pack. Also what are good for batterys nowdays ? Last I was in we had the 2000's but I am sure there are better batteries nowdays. I don't have any plans on racing, so runtime is much more important that voltage. I have allready planned on getting a Stampede. Thanks for the advice.
