I have a Powerbox Evolution Spektrum receiver and wanted to get information on the STOP/RES LED's. I am running 7.4V LiPo batteries with the voltage set to 7.4V. I wanted to know what the threshold voltage is to turn on the RES or STOP LED's? Also, does the optional LED turn on with the RES or STOP LED?
the red lights go on at about 6.9V - the external LED are connected parallel to the internal red LEDs
