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