Banggood

Bought this to monitor the leisure batteries on my motorhome as it causes problems with the alarm system if the battery gets to low fitted in minutes and connected automatically to the app which I had downloaded to my phone acts like a smart meter in your house giving battery condition power drain and history of charging and draining going back a month will be very useful whilst camping out off grid to see how much battery power we have left the working range is not great as my van is all weather

Very good item! I have installed it on my motorcycle today and went for a ride. It detects when the vehicle is started and measures the voltage during starting to check if battery is still strong. It also detects when you are riding the bike and checks the voltage during charging. Very easy to install and the app is quite good, with descriptions of the various tests. The app sync to your phone via bluetooth. I will probably buy another unit for my car as well. I TRIED TO POST PHOTOS OF SCREENSHOTS,

Yesterday I installed the Battery Tester on my sailing boat and I tested the device. It works great. Now I can easily check the status of my battery and the charging system. Furthermore I will get a warning if the remaining power falls below preset limits. I will also know when and if my battery needs to be replaced. Remark: Do not forget to activate the location service of your Android device, otherwise the device will not connect using Bluetooth.

Easy to install, no tricky pairing with mobile - it just works!

Good function and performance.
