I have an unused Servo Power Board from robotzone.com which I fail to understand to its full extent. See attachments stating that it: "..cleanly isolate current and voltage from your receiver.." etc..
I can understand how it will protect my Rx from excessive currents Rx being "downstream" from the applied power supply and my big digital servos. But I fail to understand how it can protect my Rx from sulking due to a low voltage situation in case a servo(e.g. retract servo) would stall..!
When I measure resistance between the two positive battery connectors - one for the "upstream" servo part and the other for the "downstream" Rx feed the resistance is zero. The copper lanes of the curcuit board appears to be uninterrupted from the main battery connector to the "optional" Rx power connector in the other end of the board.
In my mind any smaller "optional" Rx battery (if added) will be connected in parallell to the main battery and will only slightly - due to the added battery capacity - delay the inevitable failure of the system in case of a servo stall. Or if I simply run out of battery for any reason.
Please enlighten me to the full function of the board and/or direct me to a suitable thread if there is one. My search may have missed it. Maybe someone out there has got one of these boards. Thank you in advance.!!
PS...I am unable to attach my jpegs...WHY..?????.please advise...DS

I was not able to attach my pics so I here add some relevant links to my Servo Power Board:

Hope this helps for you to answer my questions above...Thanks
