Pros & Cons

Pros

Fyi see the pros/cons below. It seems to work as advertised. But it was nice to be educated on what the problem was before i tried to fix the problem.

The battery monitor bm2 works well and is easy to pair by bluetooth with an iphone 6 or greater. Bluetooth range is good, well over 30 ft. I have the monitor hooked up to a battery in my garage and i am able to get readings from the monitor while on t...  Read More

E-450 battery/alternator can provide charge whenever its voltage is at least. Now i know when to deploy my ctek charger or when to just let it ride.



Cons

There are 2 main issues that practically disqualify it for me. Battery charge level scale is inaccurate and not even close to industry standards. The products specifications state that the voltage accuracy should the +/-. V as low power, but at 12.

The sensor can't connect to your phone or tablet without a pin. The app is so bad i really can't tell you much about the sensor itself. It's important to know this battery monitor will only communicate with a bluetooth device.

The android app insists on running in the background, even if the system is set to prevent it, and if stopped manually in settings - apps it resurrects itself. The only way to stop the app and regain use of your phone is to reboot it. Make sure that y...  Read More

Quality


It’s especially great to keep from depleting the battery to unhealthy levels


Very easy install and it hooked right up to the app no problem


This beats opening the hood every few days to check the voltage or avoiding an unwelcome surprise due to parasitic draw


Our car battery was draining after two days if it wasn’t driven

Price


For the price this is an amazing tool


I was looking at very expensive sophisticated systems when i stumbled across this little lowcost device which turned out to work great


This cheap device will pay for itself many times over


2 this thing is what i needed so that i dont have to be in two places at once to troubleshoot this i dont have two of them wond...  Read More

Competitiveness


Better than a auto parts store test because it tracks the voltage during an actual start


I won’t know for sure if it stays within that range but i plan on comparing it to other devices mostly multimeters and seeing j...  Read More

    This cheap device will pay for itself many times over


    Posted by a reviewer on Amazon

    As far as the app and connectivity i have some concerns


    Posted by a reviewer on Amazon

    First there doesn’t seem to be any kind of security when it comes to connecting to the device


    Posted by a reviewer on Amazon

    You open the app it starts searching and pairs with it and probably would try to pair with any others in the vicinity


    Posted by a reviewer on Amazon

    I only have one so i can’t say for sure how it’d react with more than one nearby


    Posted by a reviewer on Amazon

    Second concern would be naming the device itself through the app


    Posted by a reviewer on Amazon

    I may pick up a second one and see how it reacts to having two sensors to attempt to connect to


    Posted by a reviewer on Amazon

    Standby current draw was less than advertised
