I know the rk818 has battery monitoring, but I don't know how it is
going to look or if it even uses the same values. Honestly I'm just
focused on the rk817 since that's what the only device I am working
with has on it. Do you think this should be a seperate binding or can
it be combined with the rk817 until we know for sure what the rk818
will look like (and someone ports the rk818 charger)?
