Default BLS 276 SV

Can this servo BLS276SV be run at 8.1 volts without any issues?
Thanks

Hi,

at least the German Futaba (RipMax) page is showing 6,0-8,4V operating voltage... even 6,0-7,4V is printed on the box. the 7.4V usually is the nominal voltage for hv servos (~2s lipo nominal)... i have no fear to use all of mine @ 8V (max. my bec is giving)

Ciao
Michael

Hello,

All of 3 of my BLS276SV instuctions state 6.0 , 6.6 and 7.4 volts. Nothing says anything higher. On my ESC. I set the BEC at 7.1 volts. It may run for awhile at 8.1 or 8.4 but may shorted the life span of the servo. Back in the day with gy601 with S9251 servo. This was a 4.8 volt servo. Guys were running 6. Volts since the other servos were rated for 6volts. They were having problem with the tail servo failures.
So I would think it could happen to your BLS276SV.
I have 2 helicopters setup with BLS272SV and BLS276SV at 7.1 volts and one with HC700'S and BLS276SV at 7.1 volts having no problems or needing more power( voltage). It doesn't matter which servo fails it sucks but I rather not increase the chances by using more than the instructions says.
To me if you use more volts then recommend you voided the warranty.
This is my 2 cents worth.

When Futaba lists 7.4 volts they are using the nominal 2S lipo voltage. So anything rated at 7.4 volts is designed for a 2S lipo.

As noted correctly by Phaedrus, the servo was designed and spec'd around the nominal voltage of an unregulated 2S lipo.
