Battery Charging Station

[aechmtwash11]

So now that the robot has shipped my focus has turned towards pit setup. In 2008 our team (2783) went to IRI as a pre rookie team (we used 554's robot). One of the team's there let us borrow a slot in their battery charger. It was a pretty nice one and now i'm trying to figure out how they made it. It had probably around 25 battery slots, each with an anderson connector attached to the side of the slot. Then above the connector there was a red and green LED that would display whether the battery was charged or not. If anyone is on this team or knows what team it is, I would greatly appreciate it. Also, does it use multiple kit chargers or what?
