极空BMS

It works great, u have two suggestions, 1st sort the list of devices alphabetically! It used to be this way and was easy to locate which device I want to manage, 2nd a few releases ago the keyboard input stopped working on Apple silicon Mac’s, technically the app is not supported on Mac’s but it made remote management possible. Park a Mac near the BMS and remote into it. Without the keyboard input being functional it’s difficult to do remote management.

I’ve been impressed with the app for the jk BMS, using for my batteries for a 50kwh offgrid system. App seems robust in its connection, simple navigation and the information seems to update real time. With this type of hardware I tend to use it a lot on setup, though then only periodically use it to check the batteries are staying balanced and troubleshooting. Vs other offerings from Daly and the crappy software with my solark inverter this is a solid application. Used on iPhone 13 mini.

The app itself has a nice user interface. It looks nice and the settings are easy to adjust. BUT, it causes my iPhone 12 on iOS 16.2 to slow down to a crawl when this app is launched. It makes the phone freeze up for a few seconds and then switching between apps is laggy if this app is running. I am not sure what the app is doing in the back ground, maybe collecting and sending data back to china?
