seperate batteries for Rx and servos

[Bob Reynolds]

What are my electrical connections for connecting a battery to the receiver only and another pack to the servos only. I plan on using 4.8v on each pack - probably 600a on the Rx and 2400a for the servos.

I'll be using a 2.4 RX that is sensitive to voltage cutoff. The servos will be digital and high torque. I don't want to take the chance that servo draw will bring down the voltage to get a failsafe condition on the RX.

Thanks,

Bob

Should be simple enough, red & black from the 600ma pack to the RX, red and black from the 2400ma pack to the servos, white from the rx to the servo for each channel. you may need to common up the blacks between both packs

If you dont, the only connection between the servos and the rx is the white wire and it wont work... :D

Exactly ;)

you could use a cross-loom, feed two batteries into one as normal, then splice off to form the X,

BATT BATT

Rx. SERVO

\This will not work as it does not isolate the receiver power from the servo power (the object of using two seperate sources). Do as post No.2 suggests but you definately need the common lead (black one) between the two batteries. This allows you to use a much smaller (less mah's) battery for the receiver as well.
