EE-BMS

Not really worth it. Main page lists the batteries but each battery info is a jumble of serial number nonsense and a weird percentage that means nothing. No apparent instructions to fine tune or reassign info. Selecting a battery displays gives semi decent info per battery but trying to switch to the other battery just locks up the screen.

Sometimes does not see the bms even when close to the battery

Sometimes it connects and sometimes it doesn’t. I would like to see multiple batteries at once.

This is the App for the $545 Chins heated battery and it doesn’t even detect the battery’s Bluetooth. Battery will not charge or discharge. And I can’t look in this app the issue. 12.2 v out the box. Terrible!!!!

Been in contact with Chins about it, while they have been very responsive, I can’t get it to work. Thank goodness I have the older app which is no longer in the App Store!

Think twice before buying HiMASSi LiFePO4 or downloading this App. This App falls short on so many Levels. No Passwords are provided to effect changes to Temp Setting (°C vs °F) and other settings. It’s too basic for such an Investment into their “supported” LiFePO4 battery costing over $1,500. A HUGE disappointment. Most documentation is in Chinese.

This works to monitor the temperature, state of charge, voltage and amperage if the battery. The Bluetooth rage is incredible from where I have battery hooked up in my travel trailer. There are several places that require a password to access and it’s annoying. For instance, you can see the current amperage, and there a CAL button next to it. Click it and it requires a password. Go to the setting area and there’s a full detail report that requires a password. EPROM requires a password. No password is supplied so I cannot see these items. The temperature is in Celsius with no apparent way to view it in Fahrenheit. Lastly, it would be nice to see some graphs for usage over time. Overall it works as a quick reference, but it could be better with some added dev work.
