What we all should know about Lipo batteries:

Before starting to play with your radio controlled (rc) helicopter or truck you should read this.

-NEVER run it totally flat, Lipos cells that run too low run the risk of not charging correctly afterwards.

-Always try use a balanced charger.

-Never forget incorrect charging can lead to an explosion, so only use the provided charger.

-Do not charge a swollen battery.

-After playing always allow battery to cool before charging and after charging always allow battery to cool before playing, this prolongs your battery life.

Hope this helps.
