How trustworthy are Sofirn batteries?

[JasonWW]

I asked Tracy at Sofirn if she could explain the capacity of their 26650 cells. Some are sold as 5000mah and some are sold as 5500mah.

@Sofirn

Hello.
The service is correct. Sorry for the confusion that we have caused.
As the battery capacity between 5000mah –5500mah, so some we lable 5000 and some we lable 5500. Actually the two label batteris are the same one. Thank you.
Tracy
