I've started using a power bank as an external power source. The bank sits inside a bag underneath the handle bars, with a cable to the GoPro which is mounted on the handle bars. It will last for as long as I have disk space. I use that with a USB pass-through door: gopro.com/en/us/shop/mounts-accessories/usb-pass-through-door/ADCOD-001.html
How many batteries did you go through?
