More Voltage = Less Amp Draw?

[joeling]

Hi,

From my dim memory :

P=IV where P is power & I is current & V is Voltage

where heat is wasted power probably using this formula P=IsquaredR (R is internal resistance of the system)

Of course efficiency comes in somewhere too.

From this, one can say that higher voltage X lower current gives a similar result to higher current X lower voltage. However, in the process, less energy is wasted using a higher voltage.

Does this make sense ? I hope I'm right here. Feel free to correct me if I'm leading everyone down the garden path.:o

I'm in the process working on something based on the above thinking. I am seriously thinking of using a higher voltage esc like the BK36120 or BK3695 with 8S & a 12XL motor instead of a 4S with 7XL motor.
