C-tek battery sense. Sends a blutooth check of your battery condition to your smartphone, either if it gets low, or if you haven't checked for a week. Could be very handy for some people with a vehicle they don't use all the time, like motorhomes, summer cars, etc.
about 40 quid
cheaper version
If you don't look for brand JMP
Accutire do them at 1/2 the price
No obvious mention of what the (battery killing) current drain is on the ones I looked at?

Then I looked at the JML one and it says 'about 2mW'. I make that about .2mA that I guess would be less than the other background loads of some modern cars?
