Hi I have a mini3pro and an Air2s, is it possible to recycle the batteries? If so how?
If you mean to dispose of them then the local recycling (tip) centre will take them
No not to dispose of them. just discharge and recharge.
Then fly them till they are low and recharge them back up
This might help
