I tell you what for $20 you sure get alot of very useful features/information about your batteries, I own 2 of these 1 for each vehicle & I know my voltage is a bit low to hit the remote start & let it charge up also I compete in car audio, so it helps to know the current voltage accurately & these are very close... Wish I was able to display both batts at once not have to go back & forth between them if I could suggest any additional features that'd be the only thing I'd improve... A+++
★★★★★
Great device for monitoring charge & discharge state of wet & AGM batterys. Occasionally it gets confused if to many Bluetooth sourses are being used. Ie it flips from one to another. I have six units in use.
★★★★★
The app works well, but the phone has to be pretty close to the battery monitor to connect. Anything more than 3 m or so away from the car and there's no connection. Ideally, the Bluetooth output level needs raising on the battery monitor.
★★☆☆☆
Location data is sent back to China. As proven in Hackaday. Runs on background invasively, drains battery. Beware!
★★☆☆☆
Doesn't appear to work with lithium as box says it does. It also wants your exact location, or it doesn't work. Why does a battery monitoring system want your precise location at all times.? I will be returning it tomorrow for refund.
★★☆☆☆
Keeps on closing in the Background on Android 13. Also on Android 14, even when set to use Mobile data and Battery Usage as Unlimited. Used to work like a charm on Android 12.
★★☆☆☆
RAC replaced EFB with new AGM battery and reprogrammed vehicle. Battery Voltage displays correctly, but selecting AGM in App says "Low Power @ 66%" for Voltages below 12.55v (should display 82% apparently, so useless). Cranking Test works OK. Charging Test shows "Charging System Abnormal" @ 13.30v - also useless. App desperately needs upgrading or replacing, hence just 1 Star. Does anyone know of another App that works properly with a Battery Monitor Sensor over Bluetooth?
★★☆☆☆
Unfinished app, crank test, idle test, time log all not functioning
