Gens Ace 2S LiPo 40C Battery (7.4V/800mAh)
Works in my venom pro ok. Seems to have a longer run time than the stock battery.

Gens Ace 2S LiPo 40C Battery (7.4V/800mAh)
This battery works as advertised and makes my rodeo 110 fly for about 6 minutes. It does have a couple of issues. It is heavier than comparable batteries(I cut the balance and power leads and made it two grams lighter)and although rated at 40c, seems to have less power than the stock battery. My fpv feed seems to be affected by it too. There are faint horizontal transmission lines in my picture when I use these(bought two). It's strange because when I use the 520mah version of this battery from Gens Ace, there are no lines. The stock battery has no lines. I also have an Eflite 800mah battery and it too is transmission-line free. Don't know what to make of it. At less than ten bucks each, I can live with a mild annoyance.
