Lipo battery sizing

Thanks for that,cap.I don't want unrealistic speed,I am inclined to go with 3S.I read on another site some guy was building with two motors powered with TWO 4S batteries.

Lipo battery sizing

LiPo`s are 3.7v per cell so 3s is 11.1v. As far as I know, 6s is the most cells generally used. 4s would be 14.8v.
As for the LED`s an in line resistor will reduce the voltage.
If it were mine, I would use 3s but of course, this will reduce the motor rpm. I am going to build this model next year and I will be using 3s probably with two motors.

I cannot promise to finish one project before starting another. I know, I tried.

Lipo battery sizing

Hello chaps. I originally searched for this subject under RC and electrics and was surprised no one had already raised it.
I am running a Tornado thumper 4260/06 500KV in my 46" crash tender,with a 90A Seaking ESC,and 55mm 2 blade prop.
The maker suggests a 3S to 7S Lipo battery.Does 7S even exist?
Question is, taking cost into consideration,what "s" voltage is appropriate? I will be switching 12V LED lights as well.Would 4S @
14.8V damage these? Grateful for any advice!
