I just want to add a little more. The Main thing is that it can charge 2 bats at once that would be the feature that I would want the most but it has to be able to do lipos not just nicd and nimh I was looking at the super brain 989 but it doesn't do 2 but that is prob. going to be the charger I end up getting , or something close to that if I can't get my way.
