8.4v is the top voltage of a LiIon or LiPo 2 cell pack.......

Yes as Exeter said, I meant a fully charged LiOn is 8.4V with a nominal operating voltage of 7.4V.

Re: Anyone Using 7955's on 8.4V LiOn???
that's interesting !!
i have 7955's on all surfaces except for throttle where i have a 6245 (using LiFe batteries 6.6v). i'm sure a lot of people would have the same sort of setup, a lower torque servo on throttle. so the 7955's can handle it but what about other servos? |

Re: Anyone Using 7955's on 8.4V LiOn???
For that one I'm using one of these... http://www.spektrumrc.com/Products/D...odID=SPMVR5203 It's meant for helicopter gyros that have problems with the high voltage but can be used for whatever you want. It does two channels which I was going to use the second channel for my Smart-Fly Ign cut off but I emailed Smart-Fly and he said they will handle the voltage fine. I've been using it on my throttle since the plane was new and it works great. |

Awesome, thanks Gents. Btw, what about a DA170 ignition. Can I run a LiOn direct on that too?
Thanks Robert
