| Hitech 7954sh question
Hey crawlers recently purchased a hitech 7954sh and it says its rated for 6V or 7.4V i understand you can hook this too battery power but i use lipo and its only increments of 4.2v? So the next one up is 8.4 too much voltage:/.... Can someone explain what and how i need too wire this? If all else fails i have a novak 3A/6V bec i can wire up no probs... Thanks for the help!! |

Lipo is 3.7V per cell 7.4V is 2S |

Yes you can run it straight off a 2 cell lipo. My 1.9 comp rig is set up with this servo in that manner. 2 cell lipo is nominally 7.4 volts, but max charge voltage is 8.4 v. |

So u mean like running voltage is 7.4 but a static full charge is 8.4?

Most esc's have a internal bec, voltages vary so it should be fine at 8.4v but it is a 7.4v battery so you should be good! If your worried you can always wire up the bec but I see no need!

BTW, most "listed voltages" are "nominal voltages", thus a 2S LiPO is nominally 7.4VDC but is higher when fully charged. | |
