Sold on amazon

New toy I add to my "to buy" list.
Design for car use, where seem it can show you cranking amps with good accuracy, but I guess any RVer would like to see his batteries status and diagrams from comfort of smart phone.
I ask on another forum what is the idle draw for this monitor, so stay tuned....

I think all it gives you is battery voltage.

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.
