Thesealed unit is plastic and can easily be mounted to the transponder mount of your model or anywhere else you can mount it using double side tape.The switch also features a LiPo mode and by turning this on the switch unit will auto detect low LiPo voltage and cut off power to protect your LiPo from over dis-charging. This of course can be turned off if you have other safeguards in place or using Life/NiMH/NiCad battery. The switch can also indicate the remaining capacity within your battery via LED indicators.
