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.

  1. Fred

    Easy to install and use, all the info you need, also for multiple units (no need to buy an app for multiple devices). Fairly short leads, but okay.

  2. Neil

    Easy to use and connect. It’s a great thing to have for dual Battery set ups
