Mind you, a motor with Kv=1000 on 5cells is will give the same results the same motor wound for Kv=500 on 10cells.

Nitpicking:
Kv is a parameter, not a unit, therefore Kv=1000rpm/Volt, not 1000Kv.

I see what you are saying. Kv= 830 really should be Kv = .83, but that is not how it is usually used.
Likewise it would be appropriate to write .83 Kv to indicate 830 rpm/v. But again, that is not how it is normally seen.
But I see your point. The notation should be Rv not Kv. Would you agree?
The correct notation is
k_subscript_V where
k denotes the constant and V that it has to do with voltage.
k has nothing to do with the kilo prefix commonly used in the SI system. Thus, in the example above
kV = 830 rpm/V or
kV = 0.83 krpm/V are both correct, but the latter notation is seldom used.
Note that the kilo prefix is always written k not K.
