AC200P Dies At 94% - Service Phone/Email Unresponsive

My battery was working fine for a little over a year, but recently the battery turns discharges from 100% to 94%, then skips to 0% and then off. This happens with minimal load in under an hour.

I tried reaching out to the service dept. but they aren’t answering the phone Friday/today (Mon.), and the email I sent on Friday also hasn’t received a response. Has anyone else had issue reaching the warranty/service dept? This is really concerning for me, as this battery is a very expensive, very heavy paperweight at this point.

Hi @thewoj , sorry for inconvenience.

Have you tried to calibrate the machine?
First discharge the machine to 0%, then charge it to 100% with the AC port. During this time it needs to be charged continuously, not disconnected, and not with a loaded device.

We suggest you try this first and then see if the AC200P still has this problem.
Does this happen when charging (jumping or charging abnormally fast)?

I have fully charged and discharged the machine half a dozen times with no effect.

The unit also takes less time to charge than it used to, maybe 1-2 hours maximum with the AC adapter.

Hi @thewoj , thanks for your confirmation.
It seems that the BMS board on AC200P is malfunctioning.
We recommend that you contact support via as soon as possible to have the machine returned to the factory for repairing. Thanks for your kind cooperations.

Thanks for the response, I did contact service on Friday and they have not responded yet, and I can’t get anyone on the phone either. How long does it generally take for service to respond?

Hi @thewoj , Please share us your email address or order number via private message, I will confirm with support team for you and let them prioritize your email.

Hey @BLUETTI , I don’t see a message button under your avatar’s menu (which is what the inbox indicates I should find). Can you message me so I can respond to that thread?

Hi @thewoj , Private message sent, please kindly check.
