OTG Functionality

Hi there, i’m wondering if there is an extension for doing OTG functionnality in kodular ?

I explain myself : i need, or i want probably more, to test batteries on OTG functionnality in case they were dead or not and to test capacity or health battery or something like that. I want that part in my application that i’m doing right now but this functionnality seems to be very cool if we can test those batteries over OTG.
