This is great if you want to check the status of your battery. It allows you to check the voltage, the cranking charge and it even records the date and start and end times of every trip. If you use the car infrequently, it will help you maintain the health of the battery.

It displays alot of information if you want to closely monitor your battery.I have my monitor setup on my 2nd battery (100amp agm) so I can visually see when I need to connect my solar blanket and how long I can run my fridge for before it needs a top up. And possibly detect faults or show signs it may be on its way outDown fall is that it has a 5m connection range

Purchased More than one product to monitor multiple vehicle batteries; it was a great decision. You should consider this product.My batteries cost between $400-$600 per unit. Replacement is costly, proper maintenance is vital. Some of my vehicles drain their battery because of their internal electronics even when the vehicle is not being used. I need to know their voltages regularly to ensure that they remain above critical levels. This product does exactly that. Now I can see which batteries are reaching their end of life and those that require maintenance charging. Has eliminated the guesswork and unexpected battery failures.

Excellent little tool for monitoring battery consumption and status. Bluetooth functionality (within 10m) makes it a breeze when checking battery usage.The app that it pairs with is easy to use and navigate, and also displays the trends for battery voltage. Highly recommend for the standard and dual batteries.
I had to buy a new deep cycle battery. I always use century as they are made in Australia. When super cheap came out with this offer, I grab one straight away. The monitor came with battery for free. Been using it for a few weeks now and it is working great and has a few handy features that come with the app.
Easy to install and somple app to use. Takes the guesswork out of knowing if your battery is charged or not and helps avoid it going flat without you knowing.
Top build quality. Monitors not just battery voltage but Alternator's Charging health as well as CCA! That to, in remote and in live-time to the App on your phone. Best I have ever used!
Pros - easy to install, voltmeter is accurate, bluetooth range is OK at around 8-10m.Cons - battery percentage relative to the voltage is very inconsistent making the alarm settings useless as they are based on battery percentage not voltage. Even if it did work, relying on alarms that will only transmit when in bluetooth range and connected is of little value.Conclusion - if you want a good voltmeter just install one in your dash where you can see it without opening a phone app. If you want flat battery protection you are better off spending your money on an undervoltage disconnect relay.
its been 4 weeks, should have got a product like this ages ago. also Janya won 1st please breast stroke. yeah
