Have a 3 cell 5000mah Li-Po, how long AFTER charging can I use this and get the same results as if I just charged it. It is brand new.

Rule of thumb with LiPo's is to not leave them charged for extended periods of time as it causes internal damage to the cells. If you want the most power you can possibly get then use them fresh off the charger. X amount of power loss for Y amount of time is always going to be an ever changing variable and nobody can accurately predict how the pack will drop in performance over time if left fully charged.

The longest I'll leave LiPo's charged is overnight.

I asked that question to get that answer, Don't have time to charge them in the morning for the first run of the boat so I charge them at night about 10 hrs before the run, Seem to work ok. Then I charge on storage before I but them away for another couple of weeks.
