or what about something like this.. I'd just need to figure out how to get USB-C to the 3.5mm jack
I don't really want to switch out the electronics but rather try and make a "new" battery pack.
Would there be any way to take this and figure out a way to attach a USB-C to 3.5mm that the light would plug into?
Actually, this is something which already exists: https://www.amazon.com.au/MakerHawk-Raspberry-Uninterruptible-Management-Expansion/dp/B082CVWH3R
It seems like this is currently sold out though...
