How to Get the Bluetooth BMS App for Dumfume LiFePO4 Batteries

Jan 10, 2026

—

You’re here because the Dumfume LiFePO4 battery listing mentioned an BMS monitoring app, but you can’t find that app, right? Good news: it is available and I’m going to tell you how to get it.

In my case, I have the Dumfume 314Ah self-heating LiFePO4 from Amazon (that’s an affiliate link). The listing specifically says it has Bluetooth, but a lot of people seem to think it doesn’t. It does!

It is just hard to find the app, which is why I’m writing this.

Bms Blue Tooth App

The app you need is called “Bms Blue Tooth” and is spelled/formatted that way.

If you have an iPhone or iPad, you should be able to search for that in the App Store and download it. I verified that using my wife’s iPhone.

But if you have an Android, the app is not available in the Play Store. You have to download and install the .apk file yourself.

If you contact Dumfume support, they will send you a photo showing a laptop with a QR code on the screen. If you scan that QR code, it will take you to the download page.

To save you the trouble, that is: https://scan.erweicaihong.cn/NLP8

As a less shady backup, I also uploaded the .apk to Archive.org and hopefully it won’t get taken down: https://archive.org/details/bms-blue-tooth-1.0.68

Click the Android option, then “install” to download the .apk file. If you don’t have an ad blocker, you’ll see ads that look like download links but are spam. You also don’t need to install any kind of app manager.

However, Android and Chrome think this is unsafe. They won’t let you download or install it unless you change permissions. In Chrome, you need to lower the security protection to minimum. Then you need to tell Android it is okay to install developer apps and that it is okay to install old, unsecure apps.

After you do those things, you should be able to download the .apk and click the downloaded file to install the app.

Using the App

Using the app is actually pretty easy. Just open it and allow all permissions. click the “Bluetooth” tab on the bottom, then “Search Bluetooth.”

Within a few seconds, it should find your battery. Mine comes up as “BMS-QZ4S200A-BL-0848.” Click on that, then go back to the “Status” tab to see information about your battery!

I think the “Charge MOS” and “Discharge MOS” toggles control the MOSFET switches that allow charging and discharging, respectively. So, in theory, you can use them like disconnect switches if you want.

Correction: I don’t think those are switches. I think they are just indicators of the MOSFET statuses. As far as I can tell right now, there is not a way to to disconnect the battery through the app.

Further Investigation

I am pretty uncomfortable with having to disable all of those security checks to use this app. That is pretty sketchy.

I’m considering developing an app of my own for monitoring these Dumfume batteries, so please let me know if that’s something you’re interested in.

When checking the battery status, the app tells me that the BMS version is P4S200A-50883-1.10 and that seems to correspond to the Pace 4S 200A BMS. It looks like that publishes data through simple Bluetooth characteristics, so creating an app shouldn’t be that hard.

I have tried using the PACEEX app, but haven’t been able to get it work, including by creating QR codes with the Dumfume battery’s name and UUID.

From what I can tell, the PACEEX app expects the battery to have a name starting with “PC-” and will ignore anything that doesn’t.

I also tried a handful of other free BMS apps, but couldn’t get any working.

Again, please let me know if you’d like me to develop an app for this. If there is enough interest, I’ll dive into that.

Same thing here in fact your battery that are showing. I have 0838. 😆 And 0923

I can’t get any other apps to work and definitely not in parallel. I have gotten other apps to see the batteries but refuses to connect.

  So you were able to get the “Bms blue tooth” app, but it isn’t connecting? Is that on an iPhone or Android?

    No I have it and it works for very basic information. But not for parallel or series configurations. And I have had it for about a week. I’m on android. I have been working on a web app since then trying to get more information like I had seen on other apps (that don’t work)..
    I just thought it real funny that to popped in a search a few hours after to posted and then did and got the exact same results I got but the funniest part was our battery names… mine is 10 off from yours. Like I was meant to find you post…lol…
    
    If you want maybe we can try working on this web app together then take what we learn and make an apk. I am building it from an android device. So the browser must be able to utilize Web Bluetooth api to scan for the batteries.
    Let me know your thoughts.

      Ah, I see! I only have one battery, so haven’t been able to test anything in parallel/series. I assumed you’d just have to connect to each battery one at a time.
      
      I’ve actually already made an Android app! I’m just waiting on Google to approve me to put it on the Play store.
      
      I built that to be cross-platform, but iOS is a challenge to release. I should also be able to compile a Windows, Mac, or web version. I’ll play around with that.
      
      If you want, I can send you the apk for the app I made. Email me at: coward.cameron@gmail.com

This is funny. The last few weeks people have been discovering it has Bluetooth. A month or so ago I bought one of those batteries and it said it didn’t have Bluetooth just heating. First thing I did was see if my phone would pick up a Bluetooth signal and it did. So I searched the Play store for apps and finally found that one that worked BMS bluetooth app. I kept asking the manufacturer for the correct app and they kept claiming it does not have Bluetooth. Then a week later they messaged back saying they have discovered it does have Bluetooth then all of the sudden they are advertising the battery with Bluetooth and the last few weeks everybody is realizing they do have Bluetooth on this 314 amp hour dumfume self-heating battery.

  That explains so much! Sounds like they bought and integrated the Pace BMS boards, without realizing they had Bluetooth (or maybe the engineers knew, but didn’t intend to use it and didn’t tell marketing/customer service).

Have battery as you. Finally hot app onto my S21-thanks. But app can’t find battery. See no buttons on battery to turn on bluetooth. I haven’t made any wire connections to the battery. How do you turn on the battery bluetooth?

  You don’t need to do anything to turn on the Bluetooth on the battery. As long as it has charge, the BMS’s Bluetooth should be on. Do you have the 314Ah Dumfume battery? Does it have the self-heating feature? If you scan for Bluetooth devices from your phone (in settings, not in the app), do you see one that starts with “BMS-“?
