4.8v receiver advice needed

[Rob H]

Looking to experiment with 5 and 4 cell packs on my 1/10 but the receivers I have seem to be rated for 6v. Would there be a problem operating these on 4.8v, could it cause any damage.

If so what are some good 40mhz receivers to look at which can also run at 4.8v?

There will be no problem using a 6V rated receiver with a 4.8V pack. Most BECs deliver only 4.8V. But never use a speedo with BEC and a receiver pack together. If you use a battery and a speedo cut the red wire of the speedo.

Thanks for the reply but being a novice I am still a bit confused about this, can you explain the function of the wires. What do you mean by "never use a speedo with BEC and a receiver pack together" and "if you use a battery and a speedo cut the red wire".

My set up is the norm found these days in terms of connections, currently experimenting with Novak GTB based system which has a built in 6V/3A BEC, what would I need to do? would the output of the BEC be reduced to 4.8V with a 4.8V pack?

As far as i know the output of the ESC would not be reduced in any way. So if you use the BEC of your ESC and an additional 4.8V Battery there would be 10.8V delivered to the receiver. This could blow up the receiver or even the steering servo. On the other hand the receiver doesn´t mind to just get 4.8V instead of 6V. That won´t hurt him.

What i meant was that if you use a seperate battery pack to feed your receiver then you have to cut the red (might be orange on some plugs, so I will write red/orange further on) wire off the ESC plug which you insert in your receiver. The black/brown and red/orange wire on this plug is just there to support the receiver with energy. The third wire (white/yellow) is the signal wire through which the ESC gets the information what he is actually supposed to do.

I hope you can see more clearly now. If not there surely will be someone to explain this again in better English.

My advice would be to just leave evrything with the normal BEC Voltage provided by the ESC.

I see the confusion now, I am not using an additional 4.8v battery pack or a sepparate pack for the receiver. I want to try to use the system as it is with a 4 cell pack only connected to the ESC

Ah ok.

Then just to keep it short. You will be perfectly fine using your GTB System with just 4 cells. There won´t be any harm to any of your components. Less voltage than the device is capable would never damage anything.

I´m very sorry not to have figured out what you meant before.
