How do I charge my 7.2v pack?
 

I have a supper brain, and I know what settings to use, but how do I hook it up?

you could use small alligator clips on charger wires, or do as I did, solder leads to the battery pack (after removing the contact springs) and use a small Deans connector set. I charge my 7.2 volt,6 cell battery at 1 amp on my Super Brain 959.

how fast is that cahrge

its not too long... might take 15 or 20 minutes, depending on how far down the pack is, Ive never actually run mine all the way down,super run times.
