Novak 4 cell transponder voltage booster
This is a neat little thing from Novak, its a 4 cell transponder voltage booster which basically ensures that your 4 cell powered vehicle always has enough power for the transponder because after all theres no point in having power to continue your race if your laps aren’t being counted. Available in January 2007.
The module connects between the vehicle’s transponder and the receiver, and boosts voltage to the transponder for consistent lap counting—even when the battery pack is dumped.
