Hi, a quick question:

The new RX from spektrum (SR3100) has a voltage specification of 3.5-9.6V.

Does it mean that a voltage regulator is no longer needed when using Lipo bats?

Thanks in advance for the answers

Lipo cells are good until they drop below 3.0 volts. If you have a 2 cell lipo (3.0 x 2cells=6.0volts) So if a 2 cell lipo drops below 6.0 volts it will ruin it.
the receiver works down until 3.5 volts so if you running 2 cell it would wreck the pack to keep running it.

You don't have to worry about this with newer escs (ex. Tekin Fx pro) that have built in voltage cutoff you can adjust.

Hope this helps

Ryan.

I think he is referring to the other end of the voltage spectrum. I would not thing that if the rx is rated to 9.6v that a regulator would be needed as long as your servos will handle the extra power.

My bad

If however the receiver will work with 9.6 volts that doesn't necessarily mean that it cuts the voltage down to 6.0 volts for the servos.

If you plug in a 9.6 volt receiver pack I'm pretty sure the receiver will send 9.6v to the servos, so I think you will need the voltage regulator, I'm not 100% sure though

Yes, I was talking about the other end, where the 6 volt cutoff is needed, if required by the servos.

Thanks
