I’ve read all of the threads of everyone experiencing the eb3a being dead and nothing I do has worked.
Here is my info
EB3A2214000757555
ARM v2057.11
DSP v 2056.15
I would appreciate it if there is a new firmware update that can be sent to me…thanks!
If nothing works, you can’t update the firmware. For a firmware update you need to be able to at least turn on your unit and make a bluetooth connection to it.
Hi @bluetti_dejackson269gmailcom, We really want to help you resolve the issue.
Is your EB3A unable to charge and discharge?
Could you disconnect all connected devices and try charging it again? Please ensure that the machine is in a suitable temperature environment.
@TheQuickFox’s advice is correct: if your EB3A cannot power on and connect to Bluetooth, it won’t be able to update the firmware. Even if we push the new firmware, it wouldn’t be able to receive it.
I would first try charging it via a DC source. Whether that be from a 12v cig plug/car charger cable or from solar (within the units input range of course) Sometimes these units need a “jumpstart” if they have sat for too long at a low SOC.
Hope this helps!!
I appreciate everyone’s response … as I’ve said earlier I’ve read all of the threads here and on reddit about what others have recommended to try…so here’s what I’ve done since my earlier posting. The unit does nothing until I plug in the power chord and then it shows 100% charge. Sometimes when messing with it it would show a ‘short’ and sometimes it would say it is having ‘battery communication issues’…I’ve been able to get those to go away…Here’s what I’m doing now…I put a ‘kill a watt’ meter on the power chord and plugged it into the unit and I plugged in my EB70S power brick into the solar input and left it that way for the last 4 days. It has slowly gone from 100% charge on the front panel to currently reading 50% charge … when you look at the app it shows there is 5w of ‘solar’ power going into the unit and no a/c power going into it … however the ‘kill a watt’ meter shows there is about 5 watt of power being drawn feeding the unit on the a/c side. I’m going to leave it this way to see how far the SOC meter will go down to and perhaps someone can tell me what it is doing… thanks again!
Update!
The SOC reached into the 40s and I left the a/c and ‘solar’ side inputs connected … I had to leave home and when I got back the SOC was 100% … I unplugged everything and it went dead again :(
Update # 2
I watched a good, working eb3a teardown video on youtube and the guy unplugged the main battery connection and it read 27 volts on the battery pack. I did the same thing and it read ‘0’ volts… so what does that tell that may have failed.
