Has anyone seen a simultaneous multi battery charger for the Mavic Mini?

[DJayI]

does anyone know the pinout for the battery connectors?

I came across some DJI battery pinouts, they include Mavic Mini and Mini 2 batteries.
I had never been to the site before and I cannot vouch for it or the information there. The site is from a company called, SC NIP Embedded Systems, found here.
