WEST INTELLIGENT BATTERY MONITOR
This intelligent unit works on 4.8v, 6v, and 7.2v, automatically sensing the battery connected, with 8 LEDs displaying voltages from (4.8V), 5v, 4.9v 4.8v, 4.7v, 4.6v, 4.5v, 4.4v, 4.3v. The unit is simply plugged into a spare receiver channel or if all are used via a "y" lead. It displays the voltage of the pack at the time but also records the lowest voltage that has been seen during the previous flight by the relevant LED flashing, so instead of simply measuring the voltage at the time, it also warns you if the battery voltage has gone below an acceptable level during the flight.
