Yup, BP-Revo gave me the idea of using it to watch the voltage for the Lipos.

I tried wiring it to one of the packs directly but fried the telemetry reciever. So I got a new one and monitor the voltage to the BEC instead. I also like how it monitors the motor temp as well.

I have it setup to vibrate at 145F, but with the new 6.5HV in it I never get above 120F with 70/13 gearing. I should get it up and running this week to monitor the speed as well. Just have to figure out the "roll out" to program it.
