I don't think you need to be so concerned about fully discharging and recharging your batteries every weekend. Most of the guys I fly with cycle (discharge and recharge) their batteries every month or two. I cycle mine about every two months and they hold up well.

One thing though, when you say 'fully discharge' do you mean take them all the way down to zero volts? Most of the articles I've read (and advise from others) says that you should NEVER discharge them completely to zero. They say this can damage the pack. I use a 'cycler/charger' that discharges to a certain point (I think its like 1 volt per cell) and then automatically recharges them fully.

I'm sure some more knowledgeable folks can chime in here...
