I am trying to power a HERO4 from a 4.3V power source as a battery eliminator without the battery installed, and am not sure which pins to use on the HERO Port connector. Should I use the USB power pins on 5 and 6 or the Battery In pins on 25 and 26? Should there be any additional connections?
Hello @stanleyz28213. We do not have information about this. For extended recordings without the use of a battery, we recommend connecting the camera directly to a power source (like a power bank), through the charging cable that came with the camera package.
