Your PowerBar and PowerCape are great. PowerBar is quite interesting for Automotive applications where you got 12-14V power.
I'm really looking for a UPS like cape which can give me backup power via a LiPo/LiIon in case main power goes out and re-charge the battery. Maybe is a good feature for next version of PowerCape Currently we can only have 1 LiPo/Ion backup with the included TPS but just limit us to 3.3V rail of the BBB and not the 5V rail which usually supply extra capes and USB.
