G+_David Keeler Posted July 15, 2015 Share Posted July 15, 2015 Silly question! Any reason I can't use a 5500 may 14.8V 47 battery on my HK 450? I believe I'll have to use my I inch props not 10 but can he KK handle the increased volts? My other batteries are only 11.7 volts I believe so thought I'd embarrass myself now and not just plug it in to see what happens.... Link to comment Share on other sites More sharing options...
G+_Fr. Robert Ballecer, SJ Posted July 15, 2015 Share Posted July 15, 2015 The FC always gets the same voltage (5v) from the BECs on the ESC. (Or from your independent ESC if you went that route.) -- For example, my ESCs can handle 3s-6s. So as long as I'm giving it between 11.1 and 22.2 v, it will supply 5v to the flight controller. Hope that helps! :) Link to comment Share on other sites More sharing options...
G+_Fr. Robert Ballecer, SJ Posted July 15, 2015 Share Posted July 15, 2015 BTW... 8" carbon props with a 4s battery is CRAZY fun to pilot. :) Link to comment Share on other sites More sharing options...
