Now that the new Charging Hub for P3 batteries is available from DJI: http://goo.gl/HjH2wD I'm pretty excited. Holly cow, $90! That's far and above anything I've seen out there both in price and functionality. I'm curious though...does anyone have any insight as to considerations in regards to a car inverter? I know I'm asking for a lot...wanna connect 4 batteries while I'm driving down the road. Anything I'd be well served to consider. On its own it sounds great!
