Advice for 100 watt thor build

Hello guys, I have a Thor cyclops with a 55 watt HID + ballast and stock SLA battery. It runs quite well but I am looking for more lumens/power and similar runtime (20-30 min +). I am thinking of going the route of a 100 watt HID. I tried reading through as many guides as possible such as Stollman's BFL 192 light and others but im still uncertain.

1) My first question is will an 'HB4' hid bulb fit the thor connectors? If so my plan is to buy a 100 watt HID HB4 kit off Ebay for this mod.

2) I was told to install a capacitor for safety... where would I install this?

3) Any advice for the optimal battery for the build? Stollman used a Flightmax, 14.8V LiPo Batteries, 15C, 5000mAh. Would something like that work well? Is there any guide about how to replace the SLA with the LiPo battery?

4) Any guide or advice you could provide in general would be great.

I promise to post beamshots once this beast is complete. :) Thanks.

How did this project turn out? I know this is an old post, but I figured it was worth a shot.
