Regarding battery storage,
now that winter has settled in, I made the mistake of fully charging the battery early december, in the hope to do one last ride...

Is there another way to discharge the battery than riding the bike ?

If I turn the bike ON, and leave the light on, it auto shuts down after a while...

I would rather avoid riding the bike outside, as it is -10 Celcius, not that much snow but a lot of filth and salt on the roads.

I had the silly idea to unmount the battery and slowly drain it using a 100W light bulb, but the battery connector have 5 pins, and there is no simple live +48V output available.
I guess that some wizardry is required on the 3 other pins to activate the battery. 
Any info, drawing or pinout on this battery ?
( Don't worry, I will not risk shorting something if I don't clearly figure out a safe procedure. )

Thanks in advanced for any clever ideas !


PS, The battery of my DJI drone has a small resistor and it auto-discharge itself up to 60% when not used for a week.That would be a cool addition to the bike !!!
