If you make a COTS device that consists of the battery, charger and device you can work this rules set without major changes. I've brought this up before elsewhere on ChiefDelphi and passed that concept around with FIRST engineering a few times. (I reread this topic and note that FrankJ brought this up previously).

So it's possible to make a bundled Raspberry Pi based device with a battery and sell it as a unit COTS. You must sell it to the general public essentially engineered with safety in mind. So the battery boards for the Raspberry Pi do not really cover this because they are not bundled with the system or even enclosed.

The risk of *any* lithium based battery is already present because FIRST allows laptops with batteries on the robots, again they could always change that next year, but FRC11 has used a laptop with battery several times.

Once the risk exists already it's really hard to argue we can't regulate the hole.
