Folks, it's that time again and Tattu is holding one heck of a Black Friday sale on the Typhoon H 6300ma batteries. I don't think I've ever seen them priced this low; $49.30 each and you get free shipping if you buy two. That works out to ~2.5 Ultrax batteries for the price of a single Yuneec battery. I've had a couple for a year now, with both at 40 cycles each and they are still doing great, providing the same flight time as stock Yuneec batteries. At the price it's well worth taking a look.
