I think I know where Mk.32 is coming from as I work in the same industry. These batteries can be hazardous and we put a lot of effort into battery level & system level protections to prevent catastrophic battery failures. I've seen enough damage to robot batteries over the past six seasons that FRC would probably be burning down two building per year if we went with most existing lithium batteries.
The OP was asking about demos and not suggesting using it for FRC. There are multiple threads on CD discussing LiPO for FRC. I don't see that happening anytime soon. But then I am not the GDC so that is just an opinion.

The company that made our battery makes custom batteries for the military. They know far more than me about designing a battery. Admittedly we don't slam our cannon into things full speed so it isn't getting the mechanical shocks typical in some games. Electrical loading wise it is in the middle of our last 8 FRC robots.
