Get great peace of mind as soon as you switch on your model! This little Tower Pro battery monitor will show you the exact status of your onboard NiCd or NiMh receiver battery. The row of LED's light up as soon as you turn on your receiver, showing you if your pack is full, good, or flat.
Designed for use with either 4.8 volt or 6 volt receiver packs, the battery monitor simply plugs into any spare channel of your receiver. (If you don't have a spare channel, you can connect it with a Y-Lead along with any servo).
It's so small and light, with low current draw, it can easily be permanently mounted in your model.
