5s vs 6s Battery on a Twin

(1/1)

Ken Culbertson:
I have a question about battery size on a twin.  I am building a full size (700sq) twin.  It is time to order the esc's and motors.  I have fixed on the BadAss 2320-820 motors.  I am knee deep in Jeti stuff so I want to use their ESC's. If I use a 5s battery I can use the Spin 33 ESC's but I will not be able to use a 6s battery which the motor supports.  I see very little difference in the 5s vs 6s in my other planes other than a better boost with the 6s which can be adjusted to be about the same using a 5s by the active timer.  Obviously I could use the Spin 44 but that is $40 bucks and 2 1/2 ounces heavier. 

I have been told that 2 23xx motors will actually use less mAh than a single 35xx.  If that is true than the 5s 2700 with a few more RPM's and a stronger boost may be the right answer.  Ironically my 5s batteries are 4grams lighter than my 6s so there would be no weight savings.
