Store the packs until the day before you are going to use them again. The day before you use them discharge them down to .9 volts per cell (5.4 volts for 6 cells and 3.6 volts for 4 cells) and then place them into an equalization tray*. Leave them in the tray overnight and then right before you charge them up remove them from the tray and start charging.
Leaving them in the tray over night drains virtually all the electricity from the pack, this does not seem a lot different than dead shorting them, is it?
It seems some companys want you to use a discharge tray and to make sure each individual cell does not go below .9v. Others want you to discharge the pack down to 5.4 and then use a tray to drain them the rest of the way.
Is their a lot to be gained by discharging below .9 per cell?

I have done a lot of testing in this area. I suggest a tray such as the Pro Match Smart Tray. The Smart Tray has a cutoff device but slowly continues to discharge the cells for a long time. I discharge the pack at the races using normal cutoff devices. Then a day or 2 later I tray them for 12 hours or so. The cell voltage will be in .5 to .65 range and will rise slowly when the pack is removed. Then store them. I have stored packs for up to 6 months with absolutely no losses. You will maintain voltage and run time doing this. Our enduro packs are 1 year old and have been used 3 times and tested twice. They were stored as outlined between uses. This works.

I do this
I will charge me cells at 5.5a, race the buggers get home crash out go to sleep ,wake up next day put the batts on a real time 2 tray (have to baby sit this way)wait till the lights go out (.09v) then take them off then put them away till next race(1 week store) get them out put them straight onto the charger(eaglecdcv6) & charge using boosting mode which discharges down to 5.8v(pack) then goes straight into charge & thats it
I have been doing it this way since april 04 & i just replaced the packs Why? because i wanted to

he is not............he may try to make the madison race. (he posted it on rc3's site)
hopefully he will have my new bag with him.
Yall just wait until i post the pictures of what a promatch battery did to my mini..........sometimes bunches of punch is a bad thing. The outdrives will never be the same
