1S setups with 2s receiver packs… Bad!

it is non-intuitive that a higher voltage to the servo could be worse. i think the problem is that with increased supply voltage, the servo unloaded rate goes up, but the current required for a given load also goes up. so if the circuit is current limited, a higher voltage may perform worse.

What was your solution? Is it different from the ones already listed?

Tekin Pres,
Is it permissable to wire a booster into the switch line? My thinking is that it would be a more stable a supply using the speedo regulator than relying on a booster that might not have quite enough volts/amps for every situation.
Your advice appreciated, thanks.

Is this a good supported option?
So I have been trying to find an acceptable supported option. Would this be that option? Also if all is correct with the link below what rate would I charge this battery at?

This is the charger I have and now worried it won't charge the battery listed above????

If you read a couple of posts back you can run diodes ( in the correct direction) to drop the end voltage down. Generally a 1N4007 diode will drop about 0.6V for about .1 to .5A and above that the voltage drop can get up to about .8V
Now for a 2S lipo that fully charged can get up to 8.4V fully charged and they only go down from there. The only downside to using Diodes is the power usage only stops when you have no load on the system. if there is any current it will dissipate heat therefore using up Mah's

Yes putting a reciver battery in line with the switch looks pretty good. A little dangerous to let people start doing mods like this, but it is pretty straight forward and should be more robust than a booster or regulator.
You really only need to use another 1S lipo in the switch line. Now we are getting down to little micro helicopter batteries.
With this modification the voltage cutoff WILL NOT WORK.
Good options for 1S setups with the RS.
LiFe 6.6v receiver pack
4 cell, 5 cell or 6 cell Nimh or NiCd
1s or 2s lipo in line with the switch.
2s lipo with a 6v regulator
Booster connected to the main 1S lipo
Using a Diode to drop the voltage of a 2S is not bad, but a little more complicated to wire if you want full voltage to the servo.

Would running one of these make you run slower? Less Power? It seem to me since I installed one of these I have been slower then when I ran my SMC 2 cell Li-Po receiver pack with no regulator.
Also... Can you charge a Li-Fe pack on a Li-Po charger?

Good choice though, if you don't want a regulator. You can charge it at .2 to .3 amps.
I don't have a Tekin ( hint hint Tekin Prez hook a brother up ) but here is how mine is set up.
I run the castle CC-BEC reg,http://www.castlecreations.com/products/ccbec.html you can program it to run 4.8 - 9.6 volts. It only weighs 11 grams. I use a 2s lipo receiver pack.

is a life pack pretty straight forward? Is it just plug in and go? Reason I ask is because I just got a life pack and my esc dies at WOT?..Everything worked flawless with my novak booster before this setup?
