Futaba digitals
Why are so many Futaba digital servos 4.8v only? This makes them useless for those of us who use lith. batteries with 6v regulators or those who use five cell packs. What happens if I use 6.v on them?

RE: Futaba digitals
Hi WLB,
Futaba does recommend only using 4.8V packs with any digital servos that are rated for 4.8V. But you should be okay to use 6 volts on a 4 cell pack, with them as long as are you are using a 6 Volt regulator.
You should not use a 5 Cell pack though as these packs when charged can carry a much larger voltage and this will run the risk of damaging the PC board in the servo.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.

Hi Krysta,
Thanks for your quick reply. I am not using a 4 cell pack as you alluded to. I am using a lithium pack with a 6v regulator so the servo would see a constant 6v. Please advise.. Thanks.

Hi Pile-O-Wood,
Battery packs are sold with a Standard rating of 4.8V, 6V, 9.6V, etc. This is the industry standard.
If the battery pack that you purchased has good cells in it, and most do, when you charge this pack and check it with a voltmeter, you will most likely find that a standard 4.8V pack has actually been charged up to 5.3V, 5.8V, or even 6V....this is why when you charge your transmitter battery, many times the voltage will show 11V and over although it is actually a 9.6V battery pack.
This is what we are referring to when we said that digital servos should only be used with 4 cell packs.....many 4 cell packs will charge up to and sometimes over the suggested 6 Volts.
