    I use home made dischargers that I originally made to discharge my NiMH packs all the way before re-charging. They're automotive light bulbs wired to a Trax power connector, everything I have use's them.

    I use this device... http://www.electrifly.com/miscproducts/gpmm3210.html - plugged into the balance tap with the discharger on the main lead to keep the pack balanced and to monitor voltage's. I was told the recommended storage voltage = 3.7v/cell. Please correct me if I'm wrong on that number, I'm still in the learning process about LiPo's.
    I personally store my lipo between 3.7-3.8v/cell. I also use this lipo monitoring device. It's just that I have not used the discharge feature on my charger and was wondering how much I should set. I see that you discharge your NiMH packs before re-charging, I wish I were as meticulous as you are with my NiMH.

    I just use jumper wire with alligator clips with a h4 12v to discharge. Works great and much faster than the charger will do.

    How much discharge should I set? I know the storage voltage, just not sure what is a good discharge current rate.
    Thanks in advance.

    No limit, my discharger pulls about 15 amps.
