I have a Hyperion G3 VX 4S 5000mah pack. This pack is rated at 35C continuous and 65C peak discharge. They are also rated to charge at 5C. I bought this pack brand new and have only run it 2-3 times. The performance is fantastic, too good in fact. I have decided it's just too much power for the setup I am running and have moved down to 3S. The pack comes with a Deans connector pre-installed. The pack is perfect, with only minor scuffs from the chassis and battery hold down. Retail price for this pack is $153. PM for price. You can also find more info by looking on Hyperion's page here:
