Situation: JK B1A24S15P turns off after 3 seconds. Initially after 1st time installation the connection was stable and the usual passwords and settings where being changed. Then in the middle of changing the settings this issue starts.
After turning on the BMS (with power button), connection can be made and the settings can be viewed in the app for 1-2 seconds, then shuts down before any settings can be changed. See screenshots and picture. The sound: Beep, beep, beeeeep, and shut down.
This happened with 2 brand new and similiar BMS's. At first I thought it was a faulty unit. Now after same issue with second BMS and digging through the forums, videos and manual, I am completely clueless what do try next.
What I tried and did not help:
Note: 1 screenshot is from when the BMS was 1st turned on, and staying on longer, that is way the cell wire restistance shows, and is not loading properly when the BMS turns of after 1-2 seconds in second screenshot.
Battery: 16S LifePo4 280Ah cells
Location: Battery bank for electric boat

What I tried and did not help:
- Triple checked all wiring, leads and wiring configuration.
- Draining the SOC from about 100% to about 70%
- Turning BMS on with 9V trick
- Trying to charge battery to wake up BMS
- Reinstalled app
- Bought second similar BMS and same issue
