Re: Need some help Charging lipos

I imagine this will cause some fatigue and thus have a greater potential to damage the battery?
Anyway, my experience seems to suggest fully-charged state is not that detrimental to lipo batteries, while overcharge and over-discharge are. Overcharging is dangerous and can cause explosion/fire. That's why using an accurate charger is very important. When you buy chargers, you can give up bells and whistles but not the cut-off voltage accuracy. High-end chargers allow you to set your own cut-off voltage. It may be a good idea to set your cut-off voltage to a little lower than 4.20v, to give some room for errors caused by inaccuracy of the charger. To fly 15 seconds less each flight is not such a big price to pay for longer battery life and better safety. Over-discharging is also a big no-no. It can easily kill your battery and make it totally unusable.
With a little care, I think even a cheap battery can power hundrends of flights.
