it's fire proof but i never keep a fire extiguisher around i just hope the bunker will contain the inevitable spontaneous lipo fire that's bound to happen......     ▲

Wow Ernie, wrong but wow.
Where am I wrong?

Details please.

The chemistry in lipos can produce enough heat to cause a fire?
Nitro can never ignite without a source of fire?

What am I wrong about?

We've all seen hundreds and hundreds of lipo fire threads...ESCs bursting into flames...etc...etc...

How often do we see a gallon of nitro that just caught fire all by itself?...It's actually impossible.

The only thing I do is counter ridiculous falsehoods. Lol.
Same here and here is WHY you are wrong:
Lipos can start fires.
They can. They have. They will continue to do so as long as humans are using them.

That is simply not true. A Lipo maybe a great source of fuel, very volatile if handled incorrectly, but it by itself cannot START a fire. It HAS to be shorted or over loaded, damaged so that an INTERNAL short starts the process.
Nitro can not start a fire. It requires a fire to already be there before it can burn.
That does not make it inherently safe either. BOTH power sources are dangerous....period BUT they also need a very specific chain of events to happen to make them bad. A lipo's chain can happen much easier but it still has to happen.
One factory defect or one really hot day and that garage is no more. Maybe taking your house and family with it.
They can be handled safely but they can't be left unattended in a hot building for any amount of time.

That applies to both.
They can't be charged unattended without risk of fire.
Just because you leave it does not mean it will catch on fire. It just means if you are not there and something goes wrong, you will not be there to stop it before it gets out of hand.
They can't be mishandled in any way without risk of fire.
Correct on both counts
I really don't care about semantics.
Which is why we are having this discussion
They can't produce flames on their own but they can make heat exceeding 1000 degrees.
That sir is a true statement!!!!!

Would you not agree, however, that damaging a LiPo to the point it is a potential hazard is all too easy?

Dropping a gallon of nitro fuel is usually a non-event (assuming it doesn't spill). Dropping a LiPo, however, ...

Yes I agree that it is far too easy to damage a lipo to where it becomes dangerous. I also believe that of you know it has been dropped and it is dangerous, you should dispose of it. If any of the cells look perforated, get rid of it immediately. But just because you drop a lipo, that does not make it necessarily dangerous either.

I would have to say that knowledge is the key when handling lipo batteries to always insure a positive and safe outcome.    ▲

OK..I'll concede to that.
A shorted,overloaded or damaged lipo can start a fire.

A shorted,overloaded or damaged gallon of nitro can not

Hell,I bet you could squeeze some lipos in your hand hard enough to damage them to the point of thermal meltdown.

You can touch them in the wrong place with the wrong thing and cause a thermal meltdown.

The only thing you can touch nitro with that will set it on fire is fire.
If your nitro is burning,something else was already on fire....maybe a lipo that fell off the bench yesterday and showed no signs of damage at the moment.lol...

Certain fuels and mixtures expand with heat.

Does nitro expand in summer months?

Shelf life expiration?

that's i bit of an exaggeration, i touch my lipos all the time and all over the place, in fact they at straped in place to my heli with two o-rings that Squeeze them very tight, now i don't bang them around but i don't handle like eggs either, i've had heli crashs where the lipos didn't hit the ground but the g-forces must have been tremendous, i had one crash with a TP pack that went nose in and that one took a direct hit and i mean so hard that the end of the pack was all bent up so i yanked it off the heli and threw it in my front yard and it just sat there for weeks before i remembered it was there and got rid of it. i think we all agree that lipos are dangerous BUT lipos aren't as delicate as you make them out to be.
damaged gallon of nitro can not
really, you can't think of a scenario were a damaged gallon of nitro could be a problem (leaking)......

I'm not saying they're delicate but if you just have a brain fart and cut both wires at the same time to put on a new Deans plug...It may be ruined.

If it falls from a work bench...It may be ruined.

Ruined lipos can and have started fires.

Nitro is NOWHERE near as volatile.
I can take the jug and beat it off walls...Throw it around the room...Throw it from a moving car....Pour it in a puddle and beat it with a sledge hammer while jumping up and down in it and stabbing it with a screwdriver....Worst case...It's lost.

If there is no fire present...nitro will not burn.
That can NOT be said for lipos...Not honestly anyway.

again that's not completely true, after doing a search on the web i read about a guy that got third degree burns all over his body just from tapping on a contaner of nitro, now it may have only happened once but for him i'm sure once was enough.

i think we can both agree that lipos aren't delicate and that nitro shouldn't be handled as if it was water can't we ?

We can agree on the last part but the 3rd degree burns from tapping on a container is a lie...Maybe not yours but still a lie.

Please share the story though.lol....
