Thanks but i'm still not understanding ! So i fly till whenever lets say 30% or more.. should i charge battery and then put it away till tomorrow or put it away and charge before i fly. So i guess the question always store 100% battery or discharged battery !
The batteries don't like being either full or empty, they like around 50%. If charging them to 100% when you get home results in them being at 100% for double the time that charging them on the morning of use does, then you might easily half their lifespan.
It is important that they are charged to 100% before flight, do so as late as is convenient, night before is OK if that is convenient but you will loose some lifespan by doing it that early.
If you land with them at less than 20% then charge them back up to around 50% as soon as convenient, if you really fly every day then try to land before 20% so that you don't need to bother doing this.
If you are not using them for a while, charge them to 50%, or a bit more, for storage.
Every 3 months, take them down to 7% or less and then give a single charge back to 100%. It is not clear how important this is, certainly doesn't need to be exactly 3 months, but I do think it should be done, especially if they are in storage and not being used since if they are not exercised for 6 months then they are known to die.
If you are following the above rules then set the auto discharge to the 2 day minimum.
They also don't like heat, try to keep them cool, but not freezing, and when charging aim for between 15°C and 30°C.
You should probably be able to get 500 charges out of them before they loose 20-30% capacity, loosing a few charges to convenience is only a matter of cost, not a big problem. As far as I know, as long as you always charge to 100% before use, there is no problem using them until they force an auto-land, I quite often do.
