Hi, my B300 currently has BMS v1021.10. Is this the latest version? I use it with my 240V AC200L which has BMW v1043.11. I am finding that the battery remaining percentage can be up to a 20% difference when charging up to 85%.
Hi @aaron33, we found that your B300’s BMS version is the latest one, it is not necessary to update it. If you regard their SOC as not balanced, we recommend recalibrating the battery.
Please follow the steps below:
- Please discharge all the power (charge AC & DC appliances with the power station till it is out of power and turns off automatically);
- Please charge it again, please do not load any device when charging it, and do not interrupt it while in charge.
- Once the power is 100% fully charged, turn off the machine, and leave it the whole day.
Please let us know if it does help.
If not, please contact us for further service.
