how to run servo off battery
 

How can i run my servo straight off my lipo for power

is this on an electric car or nitro?? and is your servo high voltage compatible?

most likely what you'll need is a BEC.

Sorry about that its an electric sct with a savox 1256tg it has a rating of 8.4v max and im running 7.4 2cell lipo .

What reciever are you using ?

If your reciever is capable of handling a higher voltage you can run an external bec straight off your battery to your reciever

If your reciever cannot handle a higher voltage the external bec can be connected straight to the servo

You will need a servo 'y' cable to run the signal wire from the reciever to the servo

Why use a BEC to get 2S voltage from a 2S battery?

First, if the receiver is high voltage capable, pull and insulate the positive wire (typically red) from the ESC to receiver plug. If not high voltage, do the same with the servo to the receiver. (leaving the ESC to power the receiver only)

Then replace that power, either with a splice from the positive side of the battery to esc wire. Or another possibility that would provide switching, is to splice off of the switched side of the ESC switch. I used to do this with the old boosted KO servos that also used direct battery voltage.

This new wire goes either to the receiver, or to the servo, depending on the first step.

Oh, and remember not to toss in a bigger battery, like a 3S, for some speed run fun. If that is a possibility, then the BEC starts to make a whole lot of sense. :nod: (no comment on why I mention this :lol:)

Good point Dave,

For some reason I forget to read the OP's setup and assumed he was running higher than 2s as his main pack

Cheers

Thank you dave how can i tell if reciever is high voltage or not its a spektrum sr3000 would it specify h.v. anywere on it . Im just trying to cure a glitching problem using battery topower steering servo savox and mamba max esc dont play well together.thanks for the help

All Spektrum receivers are rated for at least 9 volts per their website to the best of my knowledge. Although they don't appear to list the regular SR3000 anymore.

So, I tried this method which was also recommended by tech support at Novak with my Novak Kinetic and airtronics receiver. The problem I'm having is that the esc starts acting funny when I quickly pull the throttle to full. Normally (using the esc to power the receiver) the car just blasts off when I pull the trigger quickly. With the high voltage, when I quickly pull the throttle trigger, the motor starts cogging very badly and the car won't get to full speed (or even close). If I pull it slowly and smoothly to full, there is no cogging and it's just like normal. The only difference is how quickly I pull it on. I've tried using a ground and power in it's own plug directly from the battery to the receiver, and just power from the battery to the esc's center plug in the receiver. It's a Novak Kinetic esc. Any help is appreciated. Thanks
