Hassle-free field battery status.
The VoltWatch 12V Field Power Monitor provides convenient, affordable peace of mind for busy modelers — a quick way to check field battery voltage levels. Field batteries are usually buried down deep inside a field box. This makes it difficult to get to the battery's terminals to measure battery voltage to see if the battery needs to be charged or not. By connecting the input lead on this unit to the battery, then mount this unit to the outside of the field box, you'll never have to worry about digging down through your box to get to your field battery anyway. Just push a button, read the voltage LEDs, and that's it.
- Features easy, one-button operation — the red, yellow and green LEDs clearly show voltage range from 11.0 to 13.0V.
- Comes with double-sided tape for easy, "anywhere" mounting.
