Li-Po's are a very black art at the moment. All I can tell you is what iv'e found out by liasing with thunder power and the company that manufactures Saehan cell.
Li-Po's Number one, NEVER over discharge it! Results can be dangerous.
Li-Po's Number two, Only charge at 1C of the pack rating.(ALLWAYS!)
-1C OF A 2000MAH LI-PO IS 2AMP & 1C OF 500MAH IF 0.5AMP.-
Li-Po's Number Three, All Li-Po's must be broken in!(there is a special way)
Li-Po's Number Four, Never fully seal a Li-Po cell. Beacuse under pressure when somthing goes horribly wrong and it deciedes to expand and when it wants to vent and it could explode like a fire cracker!
I have had a cell vent and catch on fire and it's one of the hardest small fires to put out Because after the fire is put out it can easly re-ignite!
Li-Po's are already air tight factory sealed. You don't want a li-po to vent!
If you want to keep it safe Keep it wrapped up in foam and out of harms way in a radio tray.
