Depending on the BMS, that’s normal. Basically the BMS stops the charger when one of the cells reaches the set balance voltage, then the BMS drains down that cell and once it’s drained enough, the BMS lets the charging begin again.
The cycle repeats until all the cells reach the cutoff voltage, then it’s done.
Hey all. I am having issues connecting the Focbox UI android app to my unity. I have a metr pro unity as as my BT module.
I originally tried to set up my board with android app and got the message “Could not read firmware version. Make sure that select port really belongs to the FOCBOX”.
So, I connected via usb and updated firmware and set up my board. I then tried to to connect via bluetooth again so that I could get my battery percentage readings. I got the same message. Anyone else had this issue?
Can’t say I’ve had that issue. But honestly the unity metr pro has never worked for me. Pretty sure that’s my fault though. There is a metr pro specific thread that might be worth checking out.
Maybe lets ask @Skyart . I sent him my Unity with metr that definitely wasn’t working for me when I sent it to him.
Lol. Well should work then. But yeah I had issues that never got resolved but I also didn’t try very hard. It will work but idk how to make it work… I don’t care for the metr telemetry since I get telemetry on my remote anyway.
Make sure to update both firmwares on unity and metr pro. Also make sure the metr is plugged in correctly. You can also go into those threads and ask some of the metr gurus for help
I think that might have been it. First ride after battle hardening the stator went well, most of the noise seems to have gone away. I’ll do some more testing
