Unfortunately our customer support only has what is written in front of them. And then we have to look at how they interpret it. The packaging states 6 volts, but as we all know a 6 volt pack comes off the charger at around 7.2 or so, and then drops to a pretty solid 6.4 - 6.6 depending on amount of current draw. Most of our customer support guys do not fly or operate the stuff like the rest of us. So all they have is what they read. It would be awesome to have a customer support team that flies all the time but this is just not the case.
