Voltcheck

The Voltcheck displays your receiver battery voltage using LED's. I like this products because it tell you at a quick glance if you can make that "one last flight". The unit is very light weight and is made of two components; the main unit and a mounting plate that the included screws thread into. Installation of the Voltcheck is easy. Cut a hole for the unit to sit in and secured the unit to the airplane with the provided screws and mounting plate. The last step is to plug the wire into any empty position in the receiver.

When your receiver has power, the LED's will display the voltage. The unit came preset for a 4 cell (4.8V) pack. If you are using a 5 cell (6.0V) battery pack you can press the small button on the back of the unit until 5 LED's are lit. Clicking the button again will light up only 4 LED's, indicating the unit is set for a 4 cell pack. Every time power is applied to the unit either 4 or 5 LED's will be illuminated indicating which number of cells the unit is set up for.
