you need to use a special charger,

also big empty ceramic surfaces and a fire extinguisher?

Recomended yes. Or a so called lipo bag.


a bag of fire resistant material to have the lipo in.

It would need to be an appropriate fire extinguisher - LiPo fires burn without oxygen - I had one go up 10 seconds after being kicked out of my kitchen. 4 foot flames for about a minute was very impressive. It was my own fault though - I wasn't using a balance charger, I didn't use a LiPo sack and I left it unattended... my missus went berserk (funnily enough).

Saying all that - the batteries in this thread are all Li-Ion packs - a lot safer...

lipo-bag won't prevent a fire, but it'll prevent the ejection of material in fire trough the whole room...

*prevent from spreading


if that is better wording ;-)


Also lion batteries. Safer but not as potent as lipo.


7.2v at 320mah is surprisingly potent for a small craft!
