Hey folks
I converted my old backpack battery from Em3 to a large powerbank. I mounted a new plug on the battery and made a new battery cover from PVC plates to hold the battery nugget securely. So that I can connect my USB devices to the battery, I used 2 DC-DC converter. Here is a short video of this project:
Charging via usb goes well, although the DC-DC converters get a bit hot when I am at the maximum charging current.
If you have any questions, you can write them directly in the comments of the video, since I am not very often in the forum at the moment.
Cheers
