damn, is your dad paying for this! my parents have not put one cent into my hobby.... and if i want to go to the track (20 minute drive) i have to help around the house for ages... o well. wonder what they will say when they get my report card in a few weeks...
also, u can charge 2p a123's up to 30A safely, some even up to 50A... u just need an awesome cc/cv capable power supply, and then there is no need for more than one pack, as well as the fact they have awesome resell value... around $400-600 for most though :(
