Storing LiPo Batteries?

[TazD'vil]

Hi all. I am 52 years old and this is my 1st forum post so please bare with me with regards to forum etiquete because i dont have a clue.
I am a complete newbie to this hobby but I have just bought a Cheerson cx-20 quadcopter and really enjoyed my initial flight of about 10 mins or so. I have the original charger (which i don't trust myself with) but have also bought a B6AC 80W Multi Charger (which i CAN forget and not worry about) and 4 spare 2800mah LiPo batteries + safety bags. I understand that LiPo batteries must be stored at 3.7 volts but how is "Stored" defined? I mean how long can a LiPo remain fully charged without causing damage to the battery or other equipment without having to store it? I feel pretty sure that it would always be better to charge your batteries on the day of use, but what if circumstances dictated a lack of use after charging....... Then what?

Hi mate the longest I leave a lipo full is a week , if i am not going to fly after that I store charge then check then once a month
if you know your not going to fly any more after the flight your on then fly till its 3,7v per cell or store charge it when you land
I charge the night before I fly when you get the have a lot of lipos it takes to long to charge them all the morning your flying
Most of my batteries are well over a year old and are as good as new but I am very gentle on my batteries

Thank you for your quick reply. I must be missing something here? If a battery is rated at 2700mah 11.1 volts 3s then each cell is 3.7v at storage charge which equals 11.1v so what will the voltage be at full charge?

Just over 12v i think mine come up as 12.2
