BM2 new battery monitor reads on android

Got feedback about static draw - is 1 miliamp
Yes this is battery monitor, just like one factory installs on most of the RV.
The advantage are graphs, so you can check your charging voltage and convenience of reading it within Bluetooth range.
Also you can clamp it directly to battery, so you avoid connection errors.
My TC has factory monitor with digital scale, but I figured out it reads 0.5V high as there is no way 5 yo battery sitting dry for a month can hold 14.2V
For me another use is to put it on my seldom used roadster, so when I decide to take it for a spin, I can check the battery status from my living room.

I think all it gives you is battery voltage.
