|  Hitec 7950th Question
hitec 7950, says it is designed to work with a 2 cell lipo pack, can it work with a 3s? Like if you had a bec or something?

it would work fine with a bec on 3s. the servo is designed to work off 6v or 7.4 volt, it gets best performance when you supply power to it direct off a 2s battery. with 3s i would run a bec set at 7.4 volts just to power the servo and use the speed controllers internal bec to power the receiver. in a 2s system you dont need a bec, just run power direct from the battery and use the esc internal bec to power the receiver.

One thing a lot of guys don't realize is that you can program these servos for a wider than standard throw angle. This can help you get as much steering as possible when faced with certain link set-ups that force you to use a short servo arm. Narly1 |

im running my 7950 through a bec @ 7.4V, powered off a 3cell  like said, if you have a 2 cell just run some servo pigtails connected off the battery connector. |

I run mine at 6v simply because they are plenty strong at 403oz, the servo runs cooler, and will last longer than at higher voltages. | |

In your original question you asked if it could take a 3S. When Hitec says that it can run off of a 2S lipo....they simply mean that it can handle an input voltage of 7.4V. However you wish to supply that voltage is up to you.

If it can run straight off a 2s battery, the peak voltage of that is more that 7.4v. Something over 8v at full charge. Shouldn't you be able to crank your CCBEC up to 8-odd volts and the servo happily run on that? After all, the 7955 runs on 7.2v happily all day, and that's not even classed as 'high voltage'.
