This may be a dum Q. Dealing with nitro planes servos operate off 4.8 or 6 volts depending on what rx battery you use. But on elec planes what voltage is ur servos getting if your using 3 cell lipo threw the speed control?

The voltage delivered to the Rx should be listed in the specs for the ESC but I would guess it will be in the 5.0-5.5V range.

As in post #2, BECoutput voltage should be stated on the ESC specifications.
Note, the voltage output is of less concern than the amperage available.
Most ESC with BEC will handle 3-4 servos with a 2S Lipo but only 2-3 servos with a 3S Lipo pack.
The higher the power pack voltage, the fewer servos that can be handled by the BEC. refer:

Alan,
I am using the A123 battery for receivers and wanting to buy a field charger to run on DC.
Which is the best in your opinion?

Unable to recommend a particular brand as so many are simply rebadged with local importers brand label (This enables more than one distributor in each country) - name change means a variety of prices for same item - (as many Mazda/Ford parts are identical off same production line except for the package & prices, so are many products sold for RC use.)
At present for field charging Lipo & A123 am using HyperionEOS 0606i because it was imo best available and priced right at that the time.
Technology advances since 0606i bought about 2 years ago, providemore choicesnow (suggest pick one which has a data port for upgrades such as most of the EOS series). Not knowing whatis in your locality, examples:
