Cycling the battery using a cycler made for that purpose is one thing, and is good for NiCd batteries, not needed for NiMH and should never be done for LiPo packs.

Allowing the battery, any battery, to go to 0 is not a good thing. In some cases, you can polarity reversal.

Just put them on the charger when you are finished flying and restore the charge. And, the night before you go flying, put t on the wall-wart charger to top it off (NiCd and NiMh packs). Do not top off LiPo packs.
