SInce it is inherently damgerous to allow Lipos to go below 3.7V why would you need to discharge them anyway. I would think storing them at full capacity would be a better method so they will not fall below the required 3.7v level whether you store them for one month or 12 months. As long as you store them in a good fireproof container you should be good to go.
Yea I know James. That is what I meant. I am just saying why discharge Lipo's at all for storage? Especially if you do not know for sure when you might use them again. Just charge them up, and lock them away.
