I have new Lipos and would like to know what should they be charged at and also when using them how much should I leave in them so that they last longer.Also when not using them how much charge should be in them.

Most lipos come with about 3.8v per cell. If they are new I would cut my flights in half for the first 3-5 flights, to break the batteries in. As for charging, charge at 1c and for storage, most of the newer chargers do the math for you, putting the cells at about 3.8v per cell. Hope this helps.

Charge at 2.2A (1C) for longevity.

Applying the 80% rule of usage, 1760mAh is the magic number you are after.

Setting ESC cut off at about 3.5V pretty much gets you on that ball park.

However, start with maybe 3.7V for the first few flights as suggested. This will help you stay within those parameter.

I will just add that while the 80% rule works fine it can sometimes be too much if you fly hard. I prefer 75% personally and if you are happy with the flight time your packs will last a loooong time.

60% of the time, it works every time!
