Back to the issue.
I tested 2 seperate USB-C to USB-C
labled and capable of both charge/sync cords. The cord was plugged into the battery and the other end to a phone. To attempt to bring the battery level down to 50-35% storage after a day where we cant fly.
This resulted in it working with a current of 450mA - 950mA with a 6 ft cord, flowing from battery to phone.
This means with multiple usbC to usbC cords, you can bring the batts from full to 1 or 2 bars without waiting days for auto storage to kick in.
You just need to have a phone or other device (mini fans, flashlight, tablet) that you can charge up. A usbC load discharger would probably work best. This will greatly help the longevity of your batteries.
