12V Battery Monitor Bluetooth Wireless

12V Bluetooth battery monitor allows you to monitor your battery or multiple batteries (Up to 4) from your phone. You can see live data from your battery and perform a cranking test every time you start your vehicle to see more in-depth data* about your battery than just a primary battery monitor. Data is continuously graphed so you can view graphs to check on your battery, and the system automatically connects when you are close to warn you of any issues with your battery. Completely wireless, so all you need to do is connect the monitor to the battery and download the app onto your phone.

  • Easy to install 5-minute installation
  • Alerts if battery issues to your phone
  • Checks charging and cranking systems
  • Review data in graphs

FAQ’s

How do I install this? 
Installation is straight forward you just need to connect the modules cables to the positive and negative terminals of your battery. Then you can stick the unit to the side of the battery or where else you want it. Then download the app and follow instructions.

Will it warn me if there is an issue?
Yes it will. You will get a notification on your phone if there is a issue with the battery this could be low voltage when starting the engine or a issue with the charging system it will let you know.

How does it connect each time?
As it is the latest bluetooth it means that you can have multiple devices hooked to your phone. So as long as you have the bluetooth turn on your phone then when you get with 5-10m of your car it will automatically connect and update data into the app.

Can it help me find issues with battery?
Yes handy unit to have as it graphs your battery voltage so allows you to check what is going on and if there is a issue with your battery or maybe there is something that is discharging the battery that is causing the issue.

PRODUCT LIMITATIONS:

Due to the different types of battery production standards and other battery monitor standards, readings may be different by about 5-10% from other monitors. This is normal and is not indicative of a ‘faulty’/inaccurate battery monitor.

Bought three of these and connected them to my Tvan battery and the starter and auxiliary battery in my cruiser. Downloaded the multi unit app, now on one screen I can see the charge on all three batteries at once, even from inside the house.

    Pretty useful, but a bit temperamental, the cranking voltage test often doesn’t work. I have the latest firmware update.

    Very simple device and app to use. It would be a nice feature to have estimated remaining battery life in hours for those people who use it for camping purposes.
