EB3A Shuts off at 75% and wont turn back

Product Discussion BLUETTI Apex & AC Series
1

I bought myEB3A back in April 2023. I used it a few time while camping. Then, after charging it fully, I had it on my desk for a few months.

Now it seems to turn off every time it reaches 75%, while outputing AC or DC. It will not turn on again until I start charging it. None of the buttons work and the Bluetooth disconnects. After plugging in to AC or DC to chage it, the unit will power up after a few seconds and run normally until 75%. I have tried Fully charging it and each time it shuts off prematurely.

I searched for other post in the forum for similar problems. I tried pressing the three power buttons to reset the unit, but it did not work. If the unit was already off (at 75%) nothing happens. If I press the three buttons before 75% it shows the number 6203 and 5610, but the problem remains.

Thanks for any help,
James

Edit: I should add that mine does not show the “Short” error that others have posted about. AND I turned ECO mode off.

Hi @heron83562, Thank you for providing the detailed information. We have now applied to push the new firmware for you.
However, due to the weekend holiday, it will be completed next Monday. Please upgrade and test it then.

Our EB3A also turns off at 49% or 75%. It won’t turn back on until the unit’s AC charging cord is plugged into the wall outlet. We have previously updated the firmware for other problems. Hopefully you can help us.
Thanks

The Firmware is as follows
ARM - v2057.12
DSP - V2056.15

Hi @Johnny66, Thank you for the update. We have consulted our technical department, and they informed us that your firmware is already up to date.
Would recalibration help resolve the issue? Please do not connect any loads during the charging process, and test car charging and solar charging separately.
If this still does not work, you will need to contact customer service to arrange warranty service.
