LiPo batteries can carry risk, so please use with caution. LiPo are hobby-grade products and not consumer grade.  Please read your battery charger instructions, use correct LiPo approved charger/battery, and follow proper precautions. Never charge/discharge/use/store damaged or puffy batteries.  Dispose of faulty batteries at local facility (Home Depot, battery shop, recycling center, etc). Use proper LiPo charger only!  Do not charge on a nimh charger.  Use the 3 or 4 pin balancer plug only to charge through.  The Tamiya/Deans plug is output only.  Do not charge into the output plug. Only charge on the balancer port with a LiPo charger.

Charge your LiPo in an approved safety LiPo bag, concrete, metal surface/box (an ammo can is great), ceramic coffee mug, or fire-proof surface only.  Keep away from fire hazards, paper, wood, etc.  Never charge your LiPo unattended.  Always be nearby when charging.  If you have to leave, unplug from charger and wall outlet.  Unplug your battery and charger when not in use or present.  Store in a fireproof container, unplugged.  Do not leave it plugged into your gun when in storage.  Never leave charger plugged into wall outlet when not in use. Do not overcharge or discharge your LiPo too much.  Either will cause damage to its cells. Never store a fully charged battery.  Discharge to a safe level 3.6v or so.  Store at room temperatures, never cold or hot environments.  LiPo batteries are generally good for 300 charge/discharge cycles over its lifetime.  Follow proper shipping regulations when transporting, traveling, etc.
