Gaciron V9S 26650 bike light and power bank: Is the cell replaceable? Have you used this?

Hello,

I have been posting deals here for a little bit now and found an interesting product, the Gaciron V9S. This is a 26650 bike light with built in charging and powerbank. Gearbest says it uses 26650, but does not say if it can be replaced.

Has anyone used this light or this brand?
