Lithium Polymer (LiPo) batteries are significantly more volatile than other rechargeable batteries. If a LiPo battery shows any sign of damage, swelling or deformity it is an indicator of internal damage – Immediately discard it and do not attempt to charge it. LiPo batteries do not like to be exposed to air – all LiPo explosions occur for one reason, one or all of the cells in the pack is punctured or ruptured somehow, exposing their internal cells to the air.
Always monitor charging from beginning to end – never leave the LiPo unattended
Always store the LiPo in a cool area and keep LiPo batteries in a fireproof pouch
Never crash, bend, puncture or modify the battery
Never connect positive and negative leads together or reverse charge a LiPo battery
Never over charge or over discharge the LiPo battery – Overcharging can result in destruction of the battery or fire. Over discharging can prematurely reduce the batteries life
