Charge and store LiPo batteries in a location where a battery fire or explosion
(including smoke hazard) will not endanger life or property.
Keep LiPo batteries away from children and animals.
Consider how you would deal with a LiPo battery fire/explosion as part of your
normal home Fire Safety & Evacuation Planning.
Never charge the LiPo battery that has ballooned or swelled due to
over-/under-charging or from a crash.
Never charge the LiPo battery that has been punctured or damaged in a crash
(After a crash, inspect the battery pack for the sign of damage. Discard in
accordance with your country’s recycling laws.).
Never charge the LiPo battery in a moving vehicle.
Never over charge the LiPo battery.
Never leave the LiPo battery unattended during recharging.
Do not charge LiPo batteries near flammable materials or liquids.
Ensure that charging leads are connected correctly. Reverse polarity charging can
lead to battery damage or a fire or explosion.
Have a suitable fire extinguisher(electrical type) OR a large bucket of dry sand near
the charging area . Do not try to extinguish electrical (LiPo) battery fires with water.
Reduce risks from fire/explosion by storing and charging LiPo batteries inside a
suitable container: a LiPo Sack or metal/ceramic container is advised.
Monitor recharging LiPo batteries for signs of overheating.
Protect your LiPo battery from accidental damage during storage and
transportation. (Do not put battery packs in pockets or bags where they can short
circuit or can come into contact with sharp or metallic objects.).
If your LiPo battery is subjected to a shock (such as a helicopter crash) you should
place it in a metal container and observe for signs of swelling or heating for at least
30 minutes.
Do not attempt to disassemble or modify or repair the LiPo battery.
LiPo batteries are differ from conventional batteries in that their chemical contents are
encased in a relatively insubstantial foil packaging. This has the advantage of
significantly reducing their weight, but does make them more susceptible to damage if
roughly or inappropriately handled. As with all batteries, there is a risk of fire or
explosion if safety practices are ignored:
