Lipo cut off

[kev kirk]

I am using a spare lipo pack to power my tire warmers at track side. After leaving them switched on once i realise i need some sort of low voltage cutoff. Can any one suggest a simple (read cheap) method of switching them off if a low voltage point is reached. I do have an old cut off unit designed for the receiver but don't know how to adapt it. Any ideas on this or other methods.
Cheers

About £25 for a novak smart lipos cutoff thingy, I assume you're using 2cell lipos?

Hi I already have a cut of thingy for use in a car but dont know how to adapt it as it goes inline with a reciever which in my project i am not using.

dont bother about the cut off. Search for lipo monitior on ebay, there are two types, one with a buzzer and the other with a digital readout. You might even find a combined one too. From £3 up this is a simple solution for you imho.

This looks purfect, why re-invent the wheel. I will just need to adapt the buzzer to operate a relay and job done.
