So that battery monitor system works but not exactly as described. At least not for me. Don't expect to be worn for your battery when your are close to your car at least for the first 5 minutes. Then if you have an apple watch also don't expect to work. You will receive a prompt from the watch to add the device on iPhone but nothing happens. It show the overall charge of your battery. It knows when is charging and you also can see if your car charges the battery correctly but that's it Don't expect something more.

Good stuff! Bought two, one each for the main- and auxiliary batterie (2 x 100 Ah) in my Defender. Simple little housing with self-adhesive tape and two wires. Mounting within minutes. The app "Battery Sense" shows all what I need. Absolutely recommendable. No more fear anymore;-)

"Nice to have" product. App is OK as well. It shows 0.1V less than my digital multimeter though. I use it to check the starter battery on my boat. I hope it is not draining my battery when my boat is resting at the harbor.
