Default High voltage servos

My question relating to this topic is how are they powered through the reciever that operats on 4.8 volts .How do you use a S2 batt and not blow the reciever.[&o]

Check with the manufacturer of your receiver as to what voltage is safe.
It is my understanding the servos are more of a problem with high voltages.
There is a forum here for Radios & Electronics where the manufacturers monitor
their sub forums. Here is the link:

Many receivers can take the voltage, check the specs of the reciever.

If you run a 4.8 volt pack, then whatever voltage you send to the reciever is what the servos are going to get.

If you dont feel like messing with a lipo and regulator, just run a 5 cell battery, its safe for just about everything out there.

the RX has a built in regulator to regulate the voltage to actually power the RX....

the servos are on a power buss and whatever voltage goes in, is passed on to the servos.

The High voltage servos are designed to be used with the new 2.4 gig receivers that can take the higher voltages.(Spectrum{9.6volts} and some of the high end JR's) are some that I know. The will still work with normal setups but may be slower that stated.

Use this. http://www.servocity.com/html/servo_power_boards.html Thats the cheap version. It isolates the power from the receiver. You provide whatever battery you want for servo power.

Default RE: High voltage servos

Many thanks for all the top information. I intend runing my Spektrum 2.4 system with the DS378 servo. On looking into the servo I noted they make a High voltage unit and was wondering how they were connected to a reciver so hence the question. I run 6volts already but wondered what would happen to the reciver with the S2 batt . with all the good information I will do some more research and may be back with more questions. Again thanks for the quick information Yours Paul T
