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.
