Pixhawk + S800

[eyeinthesky]

Hi People i have a new 3DR pixhawk and i want to install it into my DJI S800 frame.
The first thing i need is a Power module that can handle a 6 cell because the stock one doesn't.
I found this one.http://www.ebay.com/itm/301131264504?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT
Has anyone used this power module ?

I typically build my own but decided to try one of these ebay jobs out a while back. Big Mistake! During the test flight everything seemed fine after about a 15 minute flight and then when I was about 5 meters over my driveway and landing it desoldered and copter smashed on the concrete. Never had a problem with those I built myself. Do a search for "6s battery pixhawk module" and it should be the first hit.
