I've been thinking about using these for my enclosures. I think with the varied experience levels involving LiPo's of potential users, having a reliable battery is paramount in building a successful mod. The footprint of this one below seems to be the best I can find considering it being 1850mAh. http://www.maxamps.com/proddetail.php?prod=Lipo-1850-111-Pack Definitely is pricey but for the mod I'm working with an architect to design, the price point should offset the cost for building, at least in my case.
