Exactly. There are safety concerns as well given the prevalence of lithium ion chemistry batteries. You do NOT want a large one of those punctured or shorted. Cell phones and Kangaroos have pretty small batteries, and laptops are typically above the $400 cost limit (or considered too heavy). Punctures in even small LiPo batteries can be quite destructive, and a large lithium ion battery on a FRC robot sounds like a really bad idea when DC to DC converters (or doing vision processing on the driver station) are perfectly viable alternatives.
