@Koumkouat It is recommended to do a charge and discharge cycle.

silly question but does that simply mean to take the unit from 100% to zero and then back to 100%

When the unit is fully charged use it until goes to 0% and then charge it again to 100%.

Hi @daltonivy, I appreciate your interest in Bluetti.
Yes, when recalibrating, please charge the unit to 100%. This is to set the correct starting point (0%) and ending point (100%) for the power station, maximizing the utilization of its full capacity.

In many cases, recalibration can resolve a variety of battery issues, such as rapid charging or discharging, or situations where the state of charge (SOC) seems inaccurate.

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.

Please let us know if it does help.

Thank you for @Koumkouat’s kind advice!
