BM2 Bluetooth Battery Voltage Monitors

[drivesafe]

Hi folks, I am now supplying the QUICKLYNKS BM2 Battery Monitors at a discounted price of $30 pre unit, with any Isolator or Kit purchase.


https://www.aulro.com/afvb/images/imported/2018/05/93.jpg


The BM2 Battery Monitor is a very inexpensive wireless battery voltage monitor that uses your SMART Phone as it’s display and has some unique features.


there is a FREE single battery monitoring APP and a $15-00 APP that allows you to monitor up to 4 different batteries at the same time.


The main feature is the ability to continuously display the designated battery’s voltage and the first picture is the single battery APP display, the second is the 4 battery APP display.


https://www.aulro.com/afvb/images/imported/2018/05/94.jpg


https://www.aulro.com/afvb/images/imported/2018/05/95.jpg


By far one of the best features is the 24 Hour Graph. this allows you to view the battery’s charging and discharging events for a 24 hour period ( or part there of when viewing the current day’s use ).


Again, the first picture is the single battery APP display, the second is the 4 battery APP display.


https://www.aulro.com/afvb/images/imported/2018/05/96.jpg

A major feature of the 4 battery APP is the ability to e-mail the data recorded.

This will make it very easy for someone who is trying to troubleshot a potential problem, to send the data to a third party, like myself, to have the data processed to see if there is a problem and to help resolve any potential issues relating to the battery and it’s usage.

The recorded data can also be used to show service people exactly what is going on and will make it much easier to determine if there is a problem with a faulty battery or an alternator not operating properly and you will have the evidence to make it easier to get warranty work done when it is proven there is a warranty issue.


Will post up more info relating to the features and how to use these units in the next few posts.

Hi folks and an update.

I have had quite a few people asking about the QUICKLYNKS BM2 Battery Monitors and I am now making them available to all and I have changed the info above.

If you are purchasing them when purchasing one of my isolators or any Dual Battery kits, they are now discounted to $33 per unit.

If you are just after the BM2, they are now $40 each, including free post.

How could this be connected both to a dual battery (w/bcdc) setup in the vehicle and another dual battery (in series, with an umbilical to the truck when driving and an mppt controller and solar panel as backup when not), to monitor all four batteries? Is this unit required for each battery or ???

I have experience with similar units of another brand, and yes, you need one of these units for each battery monitored.

Hi tc_s1, and if the batteries are together and wired in. parallel then you only need one BM2 for the battery bank, regardless of how many batteries are connected together.


If the batteries are wired in parallel but are some distance apart, you could install a BM2 on each battery but this would also depend on how far apart they are and what size cabling is used to connect them together.


The most likely RV setup would be a BM2 on the Cranking battery, a BM2 on the auxiliary battery, another one on any house battery or battery bank.


SPECIAL NOTE, While you could fit one to a Breakaway Battery, this will NOT meet the legislative requirements in NSW, where the CONDITION ( not just the voltage ) of the Breakaway Battery must be related to an indicator located in the tow vehicle, that is visible to the driver.


I have had two of these units in operation since October last year, and when I got two more, things got difficult with how you monitor more than one battery.


Initially I was using my iPhone for monitoring the cranking battery and my iPad for monitoring the auxiliary battery.


This worked fine but with 4 batteries, it is a pain having to change bluetooth connections between batteries and only one battery at a time is displayed.


With the Multi Battery APP, 4 batteries are simultaneously monitored and their voltages, displayed at the same time.


Plus you can either view the 24 Graph with one, two, three or all four batteries displayed as an over lapping graph, making it very easy to see what was happening in different locations ( battery locations ) at different times during a trip.

Hi Tim,
Do these have an alarm function?

[drivesafe]

Hi Ranga, and yes they have two alarm setting, which is are set in 10% capacity increments.

BUT, I have not had a chance to test this feature yet.

I am doing some more tests ( have a play ) with the devices over this weekend and will post up my findings.

I have also e-mailed the manufacturer with some questions and hope to give you more info soon.

[drivesafe]

Hi Folks and I have just received an e-mail from the manufacturer and they inform me that there is no Android version of the Multi-Batt App just yet.

The Multi-Batt App at present, is only available for iPhones and iPads at this time.

Yep, they need to get this done quickly.

PLEASE NOTE, there is both a free Android and Apple APP for single BM2 Battery Monitor use and you can add as many different BM2 monitors as you need and use them with the single unit APP, BUT it is a pain having to change between each individual monitor.

[tc_s1]

Deal breaker for me too. Could they give an eta for the android version?

[rangieman]

Yep there will be a few i for one [bighmmm]
So the world still rotates around Apple :bat:

[Pedro_The_Swift]

they can charge for it with silly apple owners is all...
a free android version will be along after apple owners have paid for it.

[drivesafe]

I have e-mailed the manufacturer and asked if they have an idea of when the Android version of the Multi-Batt APP will be available.

They have been very quick responding to my e-mails but I did not get my last e-mail off to them till Saturday, so with a bit of luck I will get a reply sometime today.

I did get info on another app that does even more than the Multi-Batt APP, but I am also waiting on an update on this as well.

As soon as I have a response, I post it up.

[drivesafe]

The manufacturer of the BM2 Battery Monitors has just informed me that the Multi-Battery APP for Androids, will be available next month.

[tc_s1]

Looking forward to hearing how it goes (but not to being on the bleeding edge of it myself after all my recent upgrades). Thank you.

[drivesafe]

Good idea tc_1s.

I do not have access to an Android phone so I will let everyone know when the Android version is available and workout some arrange with someone to test the APP.

[Chilly]

Email,sent to purchase.
Thanks

silly apple owners


Hmm... Perhaps you should read this.

Seems it might be Android users who are silly.

Any further developments on this unit?

[Witchdoctor]

Will these units monitor Lithium?

Hi and I am just waiting on an update on the Android version.

[drivesafe]

Will these units monitor Lithium?
Hi Dave and yes they will but it would be a waste of time because of the way lithium batteries maintain a constant ( same ) voltage over 80% of their discharge cycle, meaning you would only get a change in the voltage reading as the lithium battery got below 20% SoC and if you have a half decent BMS, it should shut down the battery at around that 20%.

With lithium batteries, you need to be able to monitor Ah in and out, to be able to tell the capacity remaining.

[Witchdoctor]

I have a Lithium start battery & would like to keep an eye on it.

Cheers
Dave

Hi Sandgroper and I have just received a reply from the BM2 manufacturer.

They say they are still working on the Android APP, it is just taking a bit longer than expected.

Hi Dave and again, I like to make money, but I think I would be ripping you off if I sold you a BM2 to monitor your cranking battery.

I have to be honest and say I am not sure how you would go about monitoring a Lithium cranking battery!

[350RRC]

Well, that's a deal-breaker for me.

Me too, I'm not an android.

[Homestar]

Hi Tim, what sort of distance will these operate at? If I'm in the car will it still see the house batteries in my van and vice versa? Thinking 3 would suit my setup really nicely. And I have an Iphone so easy as. 😁

[drivesafe]

Hi Homestar, while the manufacturer states 10m, I have had a couple of occasions where they had only 5m range, but move to a different location and 10m is fine.

Then on a number of occasions, I have had reading from as much as 30m.

So in the vast majority of setups, I think if you work on a 10m range, all should be well.

[Tins]

Hmm, tried to delete. Wrong item listed.

Thanks mate - PM sent regarding order of 3. [smilebigeye]

[Homestar]

Ordered 3, received them in just a couple of days - great service thanks Tim - and have finally stuck them in. Couldn't be easier, app sees them straight away and there is some cool functionality too with trending graphs, adjustable alarm levels, etc - all good stuff. And they all work together when I'm in the car - wasn't sure if the one in the van would but it does. Not that it matters too much after all as when you walk away, the bluetooth flags go red as they drop out and the last recorded voltage is shown, but as soon as you walk back within range they reconnect automatically and update the data.

Very happy. [smilebigeye]

[DiscoClax]

Any update on this being ready for Android?Bump...

[drivesafe]

Hi Clax and sorry there is no Android Multi Battery APP yet.

I have contacted them a number of times but they tell me they are still having teething problems.

[rocket rod]

Howdy all

Tim sent me 2 units recently and I have configured the 2 batteries on Android no problems. I suggest when you set them up is to connect one at a time (say main cranking battery), configure it and change it's name to MAIN, then do the other and change it's name to AUX. If you connect the monitors to both batteries and then try to configure them you won't know which is monitoring what.

[Geedublya]

They are a good thing. I Just wish the recording did 24 hours continuous rather than from 12 midnight onwards.

Hi,
does the discount apply to people who bought your dual battery kit years ago....?

cheers

[alpick]

Bought three units off ebay

galaxyS10. Android 9. 4.9 pie. Bluetooth 5.

units ask for Bluetooth pairing code, none on instructions, guessed it, 000000.

unit pairs with phone

BM2 app. Monitor will not connect with phone

BM3 app. As above.

cleared all paired devices cleared Bluetooth data and cache rebooted phone and tried a clean connection. Same issue. No connection to paired device.

guessing software compatability issue.

Anyone else?

BM2 works fine on iPad mini-plug n play as advertised, confirms android issue!

[austastar]

Hi,
BM2 App won't work on my Galaxy Note, but works on an OPPO phone and a newer Galaxy tab A.
I was using the AEG App, which is almost the same as the BM2 and I was happy with the results.
You shouldn't need to muck about pairing from the phone settings/Bluetooth menu, it just picks up the module and you select it by a hexadecimal number. But as the range is only 10m or so, that is not a problem.
You can give the module a nickname if you prefer to have an easy identification.
Cheers

[Ranga]

Just wondering which app everyone is still using.

[austastar]

Hi,
BM3 works on my new Galaxy Tab A.
Have yet to wire in the two monitors and install the new Lithium battery in the Innovan.
Cheers

[Ranga]

Got a new phone recently. What's the best app these days for these monitors?

[Eevo]

on android i use BM2

[drivesafe]

Yep, the BM2 is pretty hard to beat.

The best price for them is on eBay and you should be able to get one for around $32

[grey_ghost]

Interestingly all 4 of mine have stopped working... [emoji26]

I will try deleting the app and re-installing it...

[Pedro_The_Swift]

all 4?!?.. [bigwhistle]

[grey_ghost]

Well all 4 were working.

I actually need. Hmmm. 15?

These look good from scanning through this thread and beats the post it note and pen plus spreadsheet I've used to keep track of things. Have 2 BM2's for the price of one ctek battery sense monitor, bonus!

Is it right Tim that you need one for each battery cranking and aux if using Traxide?

Any tips on where to place the monitor under the bonnet?

[austastar]

Hi,
One for each battery, as close to the terminals as practical.

Hi duke and one is sufficient and just monitor the cranking battery.

But if something does not seem right, having one on each battery can both help to solve problems and it can also demonstrate in real time, how each battery is being charged.

This is very hand when on a long holiday, where batteries tend to get used far more than the weekend away type trip, when charging with solar.

As Austastar posted, mount them as close to the battery terminals as you can get them.
