Worse yet, when the power runs low the RCX is likely to corrupt the firmware unless you put in code to monitor the battery level (something I'd suggest if you go this route). Standard Lego firmware is designed to detect low battery condition and put RCX into sleep before voltage is so low that RAM (i.e. firmware) becomes corrupted. It has two stages of low battery detection: At 6.7 volts it turns off motors and power to active sensors and start flashing low battery icon on the LCD. It generates a periodic beep. Shuts down (i.e. power off in sleep mode) after one minute. At 6.3 volts it shuts down immediately.

(...) And I've never had a problem with low battery firmware corruption... EXCEPT at BF while running the GBC trains. How often does the firmware check the battery level (it seems to be less often than the 3ms the other sensors are polled, based on (...) (19 years ago, 28-Nov-05, to lugnet.robotics.rcx.nqc)

(...) Speaker wire and small alligator clips will make a dandy solution for extending the basic wires - after all, you really only need one very long wire here (to the "remote station"), and yoiu have a working set-up.
