Controller temperature will go up do to higher current and it will go up further due to partial throttle operation.
Current will not go down much, albeit chopped/pulsed. The motor will see/feel average current (due to larger heat capacity(, but the (much faster) electronics will see/feel the peaks.

Not as much as when going from 3s to 4s though.
Extra current with one or two cells added, simple table

The temperature mentioned is much less of an issue for controllers with active freewheeling (= synchronous rectification), e.g. the APD controller family.

Propping down will always keep current in bounds, even when one makes a transmitter setup mistake.

I'm sorry FGNewbie, I must have missed your question. Or was it power system info?
