I am working on creating a mobile xbox 360 playing station. that is small and easy to lug around. Currently I am having a problem with the battery pack arrangement. I would like to get a few hours of play out of it. The system itself uses 203 watts of power at 12 volts. plus what would be needed to power the flat panel monitor and small motherboard i would be using. I would estimate a total power draw of 16 amps dc power, and would also need a charger for it. if anyone has any info on battery arrangements or high performance battery brands, please let me know.
I am looking for a good cost effective battery that can be used, and must have a current rating of 20ah at a minimum, I would also be willing to cobble together many battery units to get to that point, as long as it is cost effective (under $400).
I finally found something. **broken link removed**. It looks like it will work with 3 of them giving me 29400mah which will power for about an hour and a half. I just have to find out if it has charge control within the batery packs, or if it needs an external charge control. Don't want any explosions.
