I just received a very sad advertisement for H accessories from CarolinaDronz. It starts out with a "special" deal for a "2-pack" of Ultrax 6300mA batteries. The price of the 2 pack has been "marked down" from $179.99 to $159.99. Worse, the add states the user might gain up to 8 minutes additional flight time by using them. Just got word from Frank at Caroline. It's a sad situation indeed. It seems the price he pays as a battery dealer is maintained higher that what Gens-Tattu sells them to the public for. Those private messages people get from "Betty" or some other name requesting people make a post about the batteries being available, giving the person posting an additional 10% off when they place an order, is the battery distributor under cutting their distributors.
