This battery monitor is perfect for my needs. Not only does it provide an instant voltage reading, it will provide a graphical view for you to analyse the voltage on your battery 24 hours a day. If you are not within Bluetooth range, it will store the data for up to 35 days and then automatically upload it to your phone once you are within range again. When looking at the graph, you can even put your finger on the time you want to check the voltage and it will do so in 2 minute increments. When looking at the instant voltage reading it’s updated around 2 times per second. This unit will also do a cranking test to measure the voltage drop plus also a charging test to make sure your alternator is working within limits. Compared to another brand (C**K) that I was looking at, this monitor is way more functional and the phone app is much better. The only minor negative I have is the other brand had a temperature readout, which I would have loved to see in this meter. So if they ever come up with a new model, I wouldn’t hesitate to buy another one if it included that function. Read full review

The monitor was a bit difficult to connect with my android6 device in the beginning and for a few weeks wouldn't work but suddenly one day it connected up automatically and has been doing so ever since, disregarding the initial problem, I have found the device works quite well, simple to use and lets me know when the battery bank is getting low.

This little device connects to my 7.1 android phone through three brick walls, I have a battery that has about 6 months before the warranty runs out. I'm hoping that this will warn me before it is totally dead. From what I have seen so far it will allow me to analyze the battery using graphs. Also it will provide evidence to the battery shop that the battery charging system is not faulty and not abusing the battery, I think I may buy another one for a second car, and track two batteries. This would have allowed me to predict the dying battery in our other car. This would make a good gift for anyone with a smartphone and a battery that needs monitoring.

It works really well and is easy to use. You can see the voltage graphed in two minute intervals very clearly and is very informative should you have solar and/or a fridge. My unit reads fractionally high but otherwise perfect. Screenshot is a fridge being run by solar with a high voltage cut-off

Amazing little piece of tech, does everything it says it will , bought it for the AGM's in the dual battery system in my 4x4 . Voltmeter is as accurate as my mid range multimeter which is more than accurate enough for my purposes of needing to know when battery is at 50% . Better value than other products such as C tek battery sense , however does lack temperature function . I've ordered another one to fit to the cranking battery and will see if its possible to monitor both batteries individually from the same app . Will post update once i know . Perth WA
