Stumbled on this idea after I just picked up my new DC020 flood light.
Its typically recommended that for long term storage you should leave your Nanos at about 40% charge – storing them fully charged supposedly degrades the longevity of the battery.
With that in mind, after trying out my new floodlight I read that you can run the light for about 2 hours on a single charge off a 18V battery.
So I ran both my Nanos in the light for 1 hour each thereby bringing them close to 40%. Now they are nice and tucked away in the preferred long term storage state.
Mind you this isn’t necessary if you use the batteries frequently or daily.
