I would discharge the batteries down and do a range check for just curiosity and see how far down the leds would go before I loose range. Maybe discharge down one led at a time.
well i did this today and i was able to drain the battery clear down to the last led indicator while still controlling the servos. i was about 300 feet away. the receiver battery was still at 5.1 volts after all that. took about 3 hours to get the transmitter drained down. pretty happy with that.
