BAT-BMS

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!

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.

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.

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

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.

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

The older version of this app used to have expected hours left of battery life based on the draw at that moment. It was incredibly helpful. I hope they bring it back.

Errors on Bluetooth connection. Never works. Deleted and reloaded twice. iPhone 14.

Installed app on my iPhone 11 using latest iOS. Connected easily to my new Chins 48V 100Ah LiFePO4 “smart” battery, giving plenty of useful data, except that 5 of the 16 cells don’t display. (I tried the app on an iPad and all cells appear there). I emailed Chins about this and they replied promptly, saying they will look into this glitch.
