BUNKER INDUST Battery Monitor BM2 BM3 Bluetooth 4.0 Wireless Battery r 12V Automotive Battery Load r,Automotive Charging and Cranking System Monitor Digital Battery Analyzer for Android & IOS

Install requires tools and knows how to connect and disconnect a car battery. For me it is not as simple because the battery is under the back seat. Bluetooth has enough range to reach inside the house from the garage. Simple to pair with iPhone, Once downloaded, the APP works fine. APP needs option to specify battery type. So notification it is useless because my AGM battery has a higher voltage range than a standard battery. I just use the history graph to check every morning before the starting the car instead. APP always want permission to use the GPS always, I changed to 'while using the app' after know the notification is useless. My battery costs upward of $400 because it is not a standard size, so this tool is a good for avoiding another costly replacement in the future.

Unreliable.It gets locked (wouldn't start) and you have to disconnect and connect again to work (until gets locked again).Buy only a good brand!Disappointed as the first I bought (Ancel) works perfectly. (Needed second one for the trailer).Too bad I lost the warranty days before I decided to returned back!!

J'utilise ce moniteur dans un VR. Comme la batterie n'est pas en action tous les jours, les informations données sont très utiles. L'application BM2 est d'une très grande clarté. Je me propose de transférer le moniteur sur mon véhicule d'hiver. Très facile d'installation. Excellent produit.

Nothing online (caution if you find a PDF, it is a scam site). The package contained no instructions, the app does not automatically connect. The recommended passwords of 0000 or 1234 did not work. It is useless.

Good product does what it says it will do easy connect to Bluetooth however I do wish it would push notifications when the battery gets low. Alert that is audibleNo instructions
