Smart phone Bluetooth Battery Monitor - BM2 - PRICE WARNING
There have been threads on this topic in the past, but none recently.
I'm looking for a smartphone battery monitor app. & associated hardware to monitor & report on battery condition for at least two batteries in my SL350 & one in the D4. If cheap enough I would add the stop/start battery in the D4 and batteries in my 2 MGs as well.
I need them to alert me to when charging is required regardless whether the vehicle is "switched on".
The CTEK 40-149 Vehicle Battery Monitor would be my first choice but at £45 per vehicle it's expensive & I'm not even sure it will accommodate 3 or more batteries.

I notice CTEK have introduced a Bluetooth monitor. I've not tried it.
