Looks like an interesting product, has anybody tried one out?

It does look interesting.
I wonder if it is powered constantly, or only with engine running?
And if constantly transmitting, how much of a drain on the battery?
Lack of info on the site...

Interesting, but ... I wonder wat the benefit is over a wired monitor, as you only have bluetooth contact within a short distance (a few meters). So then when I am within that distance (particularly sitting in the vehicle Wink ), it is easier just to look at a wired meter than grab your phone, start the app, and read voltage... Shocked Laughing Cheers, Vincent

I was wondering what the benefit of it was too. I mean, it's quite neat but I don't really see the point! I can see that it would mean you could monitor the battery without opening the car door and therefore triggering the computer (if it has one) to wake up. Or in a vehicle where a voltage gauge couldn't be fitted nicely - but do that many people actually care?

According to their website it uses between 6 and 24mW - now if you had a 10k input impedance that would be 1.2mA at 12V or 14mW plus the BLE system but that's going to be not a lot seeing as you can run BLE off a CR2032 battery for ages. So yes, by Cupboard maths their power consumption claims seem plausible Laughing

Yes I agree prob not for everyone , I suppose if you don't want extra gauges this may an option. Maybe useful to some I suppose if using leisure batteries for camping or want to keep an idea on voltage drop when when ignition is off. The range is a bit rubbish …

Hmmm.... Not too sure this is a good idea...

It's a bit irrelevant when you're driving anyway.
