Yes, and that there should be a battery node. Possibly you should add
new properties battery.txt. It's curious that different properties are
needed. Ultimately, for a given battery technology I would expect
there's a fixed set of properties needed to describe how to charge
them. Perhaps some of these properties can just be derived from other
properties and folks are just picking what a specific charger wants.
Unfortunately, we have just a mess of stuff made up for each charger
out there. I don't have the time nor the experience in this area to do
much more than say do better.
