Scott was right in his basic troubleshooting. I used another PC. 2 laptops with monitors tovbe precise. All the way to drain to zero and it did not short. Wonder why that other PC has issues with the bluetti. I am charging the eb70s back up since Scoty recommended to drain it all the way and recharge as a means to recalibrate the battery monitor. Will post the results later.

Well, i just tested my other bluetti eb70s. 7 hours with the troubled PC but no Short. Not sure what to do at this point because something must not be right with the other eb70s that shorted.
since you have two Bluetti 70S units, what if you simply did not power the laptop that is giving issues from the 70S that does not perform with it.
bigger question is why one 70s performs as expected and the other doesn’t. This was just a test but if I needed this in a power outage situation and used the one that fails I would have been in trouble. I got a few other things to try like a small chest freezer but yes, I’ll be using the good one for the trouble PC computer / desktop.
In answer to your question above…I don’t know. I have seen several posts of users having items plugged in that showed a “short” error when there was not short. This inverter seems to have issues with compatibility with some types of loads (mostly hair dryers and heat gun type devices) that other inverters do not. Why one works and the other does not??? no idea
Oh, i needed to mention as was reminded by your response email notification, the “good” eb70s actually shorted finally as well after 10+ hours.
So, looks like the power supply from the PC is definitely causing issues for the bluetti eb70s as you mentioned of some other posts. At least it’s more consistent with it’s inverter problems 
i did respond to customer support with this feedback but forget to update this post. Thanks for your input!
Update: customer support got the specs of the PC power brick that is shorting on my two eb70s. As soon as they give me an update of any findings I’ll relay it here…
Hi there!
I have the same issue.
Any resolution of this?
same for me. Just bought a new one EB70 and it has worked for 3 hrs… and then SHORT,
order SPF-EU-1705.

Hi,
How old is your unit…?
Yes unfortunately the photo is very familiar…
This happened to me with a very new unit. There was no fix for it but Bluetti replaced my unit free of charge.
Since then I have been using the power station almost daily for 6 month with no issues.
I’m still dreading it happening again.
Not sure if it makes any difference but I now try not to let it discharge below 40%.
Good luck with it.

My unit is pretty new. Bought ~1.5 months ago.

the same message here… SHORT but alternating with OVERLOAD, in a situation of 261 W shown at panel and the total amount is 800w, with a surge of 1400.
do they replace for free ? my product is brand new
Get it serviced by Bluetti or your dealer under warranty.
And for the future I would avoid the Bluetti EB series. While there are probably many happy users I have seen a bit too many “short” faults with these units. The Bluetti AC series are fine overall and I would recommend one of those.
I don’t understand why Bluetti offers the EB70S at the price point it does. I would be completely OK if they offered the discontinued model at a steal like say $200 with a 1 year warranty or something of that nature. The EB70S is MORE expensive than the AC70, but the AC70 has 2.5X times the solar potential (so it recharges twice as fast basically), the AC and DC ports can be remotely operated over Bluetooth app (even in offline mode), and you can see valuable information like the amperage and voltage in the PV input details.
Refund policy on Bluetti’s website says you can return the unit with 30 day money back guarantee, however you will expense the shipping. It says for “non-quality issues” in other words, “it works but meh i don’t like it”, you expense the return shipping cost. For “quality” issues they give you a partial refund depending on time of service, but I feel this is a grey area because if you received a defective unit out of the box you shouldn’t have to expense the return shipping. They may expense the return shipping, but they will only repair the same like model and you are still stuck with the EB70S.
@bbrauns
If you are less than 30 days into the purchase, ABSOLUTELY return the EB70S and get the AC70! Assuming you got the EB70S on Bluetti’s website, the EB70S is currently $100 more than AC70! Use code AFF5OFF for $16 off the AC70. Return the EB70S. The shipping cost will be less than $100 to return it. You saved money. And you have a more capable unit! It’s nice because right now the AC70 is discounted, so you would lose NOTHING. Also, I have the EB70S and I always hated how the battery SOC (state of charge) is in “chunks” (i.e. 100-80%, 80-60%, etc.) I like knowing the exact percentage because I’m semi OCD lol.
thank you… i am trying to return it… i just cant use it with my refrigerator, because OVERLOAD message happens almost all the time… the power is 130W and the unit can deliver 800W but when compressor starts it shut down the power unit. it cant be more than 1400 W surge…
The AC70 can surge up to 2000W for a short period of time in power lifting mode, which may be enough for your fridge. I don’t think neither the AC70 nor the EB70s is the right application for running your fridge. You will be lucky to get 4-5 hours out of it when running a common household fridge. That may be enough to get you by from a temporary brownout issue.
Assume your fridge runs at 130W. You get 80% efficiency at 130W AC. The duty cycle of the fridge runs 70% of the time. Input power is 130/0.8 or 162.5W. If it runs 70% of the time, then 162.5 W×0.7=113.75 W.
768/113.75= 6.75 hours of runtime.
Any update after all this time?
