This has been difficult to use

Now this app requires a password to change settings. There has not been one previously and there is no way to request a new one

The batteries drain separately one is at 1% and the other at 99%. All the time

Password?

All of a sudden you need a password to turn on and off your battery. And I don’t know how to make a password. And or where a preset password is.

Can’t use golf cart after update

After recent update now I am unable to use my golf cart.

App update 7/9/26

Ever since the app update to fix some bugs I have not been able to use my battery. The functions in the app do not work to switch the battery on and off

Give us what we want!!!

The app developers removed the ability to toggle “charge” and “discharge” switches. Now it’s one of the worst BMS apps available. Save yourself some hassle and download a different app. Or maybe developers will eventually revert to the last software version that has NO issues.

Unable to connect to phone

Downloaded app and have been unable to BT connect. It ask me to provide CCard info and states there will be no charges. Uncomfortable with this request.

Bluetooth Connectivity

Bluetooth connect connectivity worked for a while and then recently stopped working altogether. Multiple members of my family have the app downloaded to connect to the golf cart and they all worked flawlessly until about two weeks ago now no one can connect.

Doesn't work

The app no longer works. What's going on?

No Documentation

This app reliably connected with my 48 V golf cart battery. The problem is there are some things in there that are kind of cryptic. It would be nice if they had a manual which described each parameter in the app. I even looked on YouTube to see if somebody had done an educational video on this app, but there were none that answered my questions.

Works for me

I use the app to monitor the 48v 100Ah LiFePO4 battery in my riding lawn mower. Works great for me.

Ramaining Time

Please re-enter the remaining time during charging and discharging. I don't understand why you removed it

Battery warmer

Does not allow me to turn on the battery warmer.

Does not show battery percentage anymore

Does not show battery percentage anymore

Great app. Works will all 8 of my CHINS 48VDC 100ah lithium batteries, & an added bonus is that it also displays information from my DC powerhouse batteries!

Reconnection Issues

App is pretty basic and no updates in the 6months I’ve been running it. Provides the necessary info to monitor the battery. But the issue is it never maintains Bluetooth connection. Every time I re-open the app I have to go through the reconnection process. This only takes a 5 seconds but would love it if it could be fixed.

Acceptable but limited function.

For a free and basic BMS reporting application this is an acceptable application. Everything works and it provides basic statistics and is easy to understand and use. Documentation is basically nonexistent but given how simple the provided information is that is okay.

Battery doesn’t always auto connect which is frustrating and I would like to see specific documentation as to setup and maintenance of batteries with compatible BMS functionality.

Missing Information that used to be on the app!

What happened to the “time remaining to charge” and “battery capacity” information??? There was no reason to remove those helpful features!

Starts on the wrong page.

Battery disconnects and doesn’t reconnect automatically. I like that, it keeps the power from being wasted on a BT connection.
But why does the app open on the data page when you have to go to the connection page every time? Start on the connection page, then have it go to the data page.

Just Works

No issues. I would like to see time remaining at given amp draw.

Stopped shower battery percentage

The battery percent at the top shows nothing. I tried a restart and reinstall and it doesn’t work still.
