I’m having this problem where my AC180 gets to 50%, it would go straight to 0% and shuts off. When charging, it would charge normal from 0 to 40%. Then it’ll go from 40 to 100% in minutes. It’ll stop charging once it gets to 100%. I’ve tried to recalibrate the SOC by discharging to 0% and recharging to 100% four times now and the same pattern above persists. It feels like I got half the capacity it should now. Wondering if anyone have this issue and if there was a fix? Purchased 8/23. I see people have newer firmware but my app says everything is up to date.

Hi @manng, Thank you for getting back to us so quickly.
We have requested to push the latest BMS firmware for you.
Our IT department will push the latest firmware to your unit in 24 hours.
Please upgrade the firmware tomorrow. Please do not load any device when upgrading it.
After that, please try to complete the cycle of discharge and charge to correct the SOC. The problem will be resolved.
Please follow the steps below to recalibrate it:
Please discharge all the power (charge AC & DC appliances with the power station) until the SOC is 0%, turn off the machine, and leave it for 3 hours till it cools down.
Please charge it again, please do not load any device when charging it, and do not interrupt it while charging.
