I'm about to put my MVP 20W and MVP 3.0 in the back up drawer. They've serve me well since the beginning of the year but I'm moving on to REO's. Should I store them charged or empty? May need to use them again or pass them on to someone else.

You never want to leave the batteries empty. Even if you store it away, you want to bring them out every once in a while and recharge it. Letting them totally die will kill the battery.
Lithium cells come new with a 3.6-3.7 volt charge, I assume that is for optimal shelf life. My smart charger for my RC batteries has a storage cycle for li-po's, it will either charge them up to, or discharge and settle them in to about 3.8 volt. I've wondered what is best myself, but whenever I store any kind of lithium cells, I trust the nominal voltage for storage mindset.

As I understand battery should be half-full and never stored in hot environment. Air-conditioned room is OK. Slightly better if stored in refrigerator (but not by much). If you decide to use frig, to not use device the day you take it out, let it to warm overnight (there could be some water inside because of condensation).
I am glad you asked this question because I have been wondering this also. I just keep forgetting to ask when I am on this site. Lol
I'll second ENAUD's suggestion. R/C battery packs can each cost as much as a high quality mod, and that's how I store mine.
Did the person telling you that sell batteries by chance?
No, but he was looking for some VTC4s and knowing him he wouldn't mind rooting through my recycling.....
Cool, I just put them in the drawer when I'm done with them. I've only managed to run the MVP20W down until it quite once and now that I have tons of charging chords around I doubt either ever gets below half. I just charge them where ever I am until I leave and they may be fully charged once a month.
meleemark, nice cig line but that break even thing never quite happens, there will always be something you just have to buy when it gets close.
Store them at about 3.6 volts I believe.
When you buy a brand new battery, 3.6 is what they normally seem to measure.

I keep telling myself after buying a new mod that I'll break even a little later........and then......oh.....that new mod looks pretty.
