Query regarding voltage input at C-port (VERSION_20200811) #252

Hi,

I have bought some Tcall SIM800l modules of VERSION_20200811 for my IoT project. I have a question regarding the max voltage that I can give on its USB port safely as I am planning to connect it directly to battery via its USB C port. Can I give say 8 V at the USB C port ? Further, could anyone plz share its datasheet if possible as I am not able to find it on their website.

Thanks.

The safest operating voltage is 5V
