Help with Giant receiver batteries

Postby kemp83 » Mon May 20, 2013 6:10 am

Hi! I am building a Great planes extra 330s 27%.It is my 1st Giant! I will use a CRRC Pro GF50i, futaba R617 receiver, and 7 Spectrum A6010 digital servos.

Spectrum A6010 Technical details
Control: digital
Ball bearings: 2
Input voltage: 4,8-6,0 Volt
Torque 4,8 V approx: 62 Ncm
Speed 4,8 V approx: 0,19 Sek/60°
Torque 6 V approx: 72 Ncm
Speed 6 V approx: 0,14 Sek/60°

So, what I need help with, is what kind of receiver battery should I use to be able to fly 3D...hover and staff...

(1)I already know that NiMH are not good enough for my appplication. Is a pair of LiFe (A123.....is it the same?) batteries the best choice? Or a pair of LiPo?

(2) How shall I connnect them to the receiver and servos? Will I need a regulator like with Lipos, a special switch or just a heavy duty switch and a Y cable? I know that powerbox sensor is a good choice which uses in parallel both batteries and regulates the voltage at the same time, but is a little expensive...Are there any other options?

(3) How risky is it to use just this one and what switch should I use with it?

Turnigy nano-tech 3000mAh 2S1P 20~40C LiFePo4 Receiver Pack

Please give me specific products if possible and keep in mind that simplicity and low price are prefferable...
Thanks!

About the CRRC GF50i 50cc it's not all good news:

If you haven't bought one already perhaps you should reconsider.
If you are paralleling the battery packs for redundancy see this thread:

The battery packs you intend using will be fine, the voltage drop of the diode will bring them nicely into the 5-6 volt range for receiver and servos, no extra switching required.
