We all have that day when we want to fly, but our life, weather or wind gets in the way. We charge up the batteries to full then realize we have to discharge them to storage. I recently bought a USB-C to USB-C cable hooking the full battery up to an old phone to try to discharge it but nothing happens except android battery icon flashing. I think the BMS in battery or something in cable won't let the battery discharge its current through the usb-c port to the old phone. This would have been the easiest way to get them all down to 50% without putting it on the anafi and discharge for more wear and tear. Just want to report that this method of discharge storage doesn't work. It is likely somewhere I read in the manual that the anafi battery can indeed be used as a power bank to discharge via usb-c anyone know how?
Discharge batteries when can't fly

You dont want to have a full battery for 2 weeks before auto discharge starts. That kills lipos. You have to discharge to 40-50% right after you are done flying or if you dont use a fulll battery within 24hrs of a full charge then you need to discharge it.
think I am missing something here....LOL... what do you do if you have used 60% or 80% of battery power on a flight, surely there would be no need to discharge the used battery?, I have had my Anafi for nearly two years now and I don't discharge them at all, I just allow them to go into hibernation mode.....but as I stated I could be missing something or a complete misunderstanding on my part of what you are trying to convey......
what do you do if you have used 60% or 80% of battery power on a flight
I wrote "what do you do if you have used 60% or 80% of battery power on a flight" meaning there would be 40% or 20% left in the battery, I for one do not allow any of my drones lipos to get down below 10% (DJI or Anafi) , we all have our different "Modus Operandi"
Misunderstandings here between us......

I think you are missing the point of parrotanafifan post. He wants to have storage capacity of about 50% charge when he is not going to be able to fly for a few days. I agree with this as it is helps to maintain battery health vs an over or under charged battery while in storage. Parrots auto hibernation takes 10 plus days to discharge batteries to a healthy storage voltage. So he is looking for a way to manually discharge batteries if they are fully charged and is not able to fly. I also recall hearing about a method to accomplish this similar to what he posted but have not tried it. To answer your other question about having less than 50% on battery after flight you should charge it back up to 50% for storage.
It’s really important to keep Anafi batteries in good health as it is not uncommon for batteries to fail mid flight without warning
Happy flying
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.
