Here are the settings I am using, and from my research this is what is recommened. Primarily they are the recommended seeting off the LRP Competition 2 Charger. Run the pack in the car till the pack dumps. Plug the pack into your charger and use these settings to DISCHARGE the pack all the way down. 10 AMPS at 5.4 Volts. Then put them into a discharge tray and equalize them down to .9 Volts, or till the bulbs go out on less expensive dischargers. Then CHARGE them back up at 5.0 AMPS at 10 mV. They get a little warm, so repeak them right before I go out to use them on the track; takes about 1-3 minutes.
Heres the link with the information:
