Hi
I have the CTEK Bluetooth sensor, works well easy to use app
I used a cheaper version on my Audi and it was never as reliable/successful but the App had more functionality.
Bought my CTEK from a recommendation on here, and as you as a means of monitoring battery drain etc.

I use one that’s sold as BM2 online. Usually under £20.

Cool, I'll have a look, my battery is inside car so a pain to get at without waking it up

Thanks I saw them on Ebay, how was reliability? Was a few issues in reviews but I did notice quite a few updates to software this year to fix inconsistent readings

Thanks

Hi
I just googled the BM2 and that was the one I had on my Audi which I never had much success with, though I will admit that I fitted it and soon after stopped using the car regularly and didn't open the App for ages as the car was laid up has been laid up for the last 18 months, I have recently put the car back on the road and now the sensor seems to be dead.
I would buy another but the CTEK I felt was a better quality, more reliable.

It’s been fine. Once or twice a day it sends a message to the phone regarding voltage. Seems consistent day to day, by which I mean the voltage gradually drops if the car is not in use. By the time it hits 65% we generally charge.
