“I bought one for the 170Ah auxillary battery that I have for my camping stuff and ended up getting another one for the starter battery as well. It's very handy to see the state of charge from my phone... so easy to fit and setup.
The app shows both batteries at the same time.”
“Quite a handy piece of equipment. I have a battery in my van which is difficult to reach. I can now see with ease the state of charge & condition of the battery.
I'm getting another for the second battery in the back of the truck.”
