I was stuck in line for COVID testing so I thought I would pull apart my carcam that was not turning on because of a stuffed internal battery causing to to get stuck in an infinite power cycle loop.
I pried the back off to expose the PCB and screen.
I didn’t have a screwdriver to pull the PCB out so I tried looking up the main IC spca1521a-hl091 datasheet
I found this datasheet which is from the same manufacturer but a different chip

The battery is a single cell LiPo with a protection PCB.
