Hi, I need technical support please because my EB70 is showing the error “short”. I connected a load with 690 watts maximum power and after that everything went dark. The EB70 is no longer responding. When I connect it to the 230V charger, the battery indicator first rises to 80% and then the red error message “short” appears.
QUESTION: What do I have to do to get my EB70 operational again?
Many greetings, Jörg
This is a fairly common issue with the EB70. You should contact your seller or Bluetti support. They may ask you to do some tests to identify the problem (and if it is a defect of the unit or if a connected load is causing the short) If it is identified as a defect in the unit it will need to be repaired or replaced. You can search the forums and the internet a bit for “EB70 short” to get an indication of what other users with this problem experienced.

Thank you. I had hoped that this could be solved with a “trick”. I connected a consumer with 690W to the EB70. The consumer was adjustable and therefore certainly limited to 3A at 230V. The EB70 is supposedly capable of 1000W. This irritates me that this error message now comes up. I have already spent a lot of time looking at or reading various articles on the subject. Unfortunately, I have also come to the conclusion that the only thing that will probably help is a return or (as I would like) an exchange. So far, I have been thrilled with the device and would have liked to have it repaired.
p.s.:
My recommendation to all those for whom the short error comes and stops: don’t waste time trying around. It must be sent to a technician who will repair it.
@JoergS
Sorry for inconvenience caused.
Could you please try remove all load devices, reboot and see if the fault can be cleared and used again, and try to load other devices to see if they work properly.
If it still doesn’t work, you need to support the department for further solutions.
Thank you for your suggestion. I did that and unfortunately it did not work. My seller has contacted bluetti and I hope for an exchange, especially since I am actually thrilled with the device.
Same issue, i already contact my seller n waiting response from bluetti team… hope it can be solve…
Anyone ever get a resolution here? Having this issue with my eb55, had been working great until this weekend. Only ac is affected
Usually these issues get resolved via a factory repair. Contact Bluetti or your seller for support, you may need to do a few small tests and if these do not provide a solution you can get a repair under warranty.

I also have the same error where I plug in the AC charger and the short circuit warning comes up on the display.
I have opened up the unit (EB70 UK version) and I have found that there is a short across the main battery terminals and also the charging input terminals on the main distribution board (when board is completely isolated from the rest of the system)
The unit doesn’t power on, presumably to protect itself from further damage.
It would be helpful if Bluetti or somebody in the know could point me in the direction of what could be causing the fault… @BLUETTI_CARE

Hi @YamR1Jay85, In general, we do not recommend customers disassemble the unit themselves, as non-professional handling may cause damage to the power station.
We consider the issue might be related to the mainboard. Please take proper safety precautions, then through the B+ and B− terminals on the BMS board to measure the total battery voltage.
If it is indeed a mainboard issue, please contact customer service to arrange a repair service.
If you have any questions about how to reach the appropriate customer service team or concerns about the service process, please send us a private message with your order information so that we can arrange priority service for you.
@BLUETTI_CARE Thank You for getting back to me.
I am a qualified Electronics Technician and am competent enough to take apart to investigate further.
I have put a meter on the output from the battery pack to the main board and I’m reading just over 23 Volts.
The main board appears completely undamaged with no components showing any sign of excess heat or bad solder joints.
This is why I’m seeking further advice.
I appreciate any further details and guidance you can give me. Unfortunately, I acquired the faulty EB70 from work and I have no proof of purchase or associated warranty. I’m also conscious that the cost of submitting for repair could cost nearly as much as a replacement unit. Is a repair to the main board cost effective?
Hi @YamR1Jay85, I agree with your opinion — replacing the mainboard would be more cost-effective. Are you located in the UK? We need to confirm with the nearest warehouse in your area.
Next, we will message you to collect specific information so we can arrange further service for you.
