Best way to Ignite a Lipo ??
Douse it in Nitro and light a match.

Or with gas if you prefer the latest rage.

Put the smallest marginally feasible CASTLE CREMATION esc on your heli,
the lowest C rating battery you own in your heli. Program the governor for 3K rpms. Climb way up high into the noon day sky and dive down like a hawk on a rabbit. Look over to your buddies and make sure the Iphones and cameras are rolling and nut-it and do the fastest ballistic fly-by you have ever done and stand-by for the fun, the POP, the SMOKE, the FLAMES and finally the THUMP as you hit the ground. Make sure you have a few fire extinguishers so you can fight the ensuing brushfire. Have Fun.

Just got rid of a 5 cell 3600 over the past weekend. I shot it point blank with a .22 rifle. There was no fire for me, there was what seemed to be a never ending generation of thick heavy smoke that lasted for quite awhile, a boat load!!! And it was generated with some velocity from the pack. Poisonous nasty foul smelling smoke at that. I guarantee that one pack could have filled the first floor of any home. In addition was the heat generated, as I said no fire, but it was melting itself. A truly evil and dangerous event. 10x what a 3s would have done. When it was finished smoking I used tongs and put it in a bucket of water for a few days before disposing of it. It was in several chunks. Wish I would have videoed it.
Your concerns for smoke are spot on as well as it melting/burning any other packs it may be with. That would surely happen. How far does one need to go with the proper storage for these is anyone's guess. I keep them in ammo cans and do not lock the lids (pressure), and they are in my office at home. Is that good enough? Probably not. If they were to go off, I feel the fire part would be contained, the smoke would be devastating and kill my pet too. Where would I really like to keep them? In some small shelter box in the middle of the yard. However weather would probably not permit that (heat/cold/moisture). Your concerns are justified. Guess it all boils down to what makes you feel comfortable. As you can see from my rambling here, I am still not at peace with myself and my lipo storage.

I have never been able to get a lipo to light. I have tried it all. Dead short, puncture, throw it in a bon fire, nothing. Either I am blessed or the whole thing is hyped to a greater level than it actually is. I still practice safe care procedures so maybe I am satisfying some sort of lipo god.

Over the years our club has tried most every way of setting off LiPo's. That includes the nail on a stick, dead short, over charge, direct connection to a 12V car battery, etc. However, we mostly shoot them with a 22 rifle. Every once in a while we have a "shoot off" for LiPo's. Everyone brings their dead or dying LiPo's and they are all set up in a target array - close enough to see what is going on but far enough to be safe AND to loudly point out when someone is having trouble hitting a battery.

We get the best results when the targets get a fresh charge just before the shooting starts. When a pack is hit the results vary from nothing happening to a great deal of smoke being produced. In about four years of doing this, I've only seen one pack (4S 2200ma) actualy explode. The pack had a fresh charge and was real puffy. The fire ball was about 4 feet across and very intense. Some packs have given a little flame towards the end of the smoke production, but not very often.
The older I get, the fewer things seem worth waiting in line for.

Well, thanks for all the comments. This is what I'm doing and the reasons for doing so. For the bunker, with a friend, were making some forms to pour concrete on a 1 in. concrete slab.I'll have 8 concrete boxes on the slab, just big enough to hold the largest Lipo's I use. The whole bunker is not that large, and will be topped off with a 1 in. slab, with a handle on top. This should contain any fire, and not let multiple Lipo,s to ignite. To get rid of any smoke, a fan large enough to exhaust the smoke thru a large hose, one like the hose on a dryer, and exausted to the outside. The fan will be turned on by a smoke detector. REMEMBER, from what I understand, you maybe can contain the flames, but the smoke can be VERY toxic to you, your children, and pets.Even deadly !! The SMOKE may be the most dangerous effect, if not flames. Also, check what ever you use to store your Lipo's with a handheld blow torch. For LIPO bags, heat up the inside of one, and see how hot the outside of bag gets. Same with any metal box, you may be getting a false sense of security, and then try the blow torch on a 1 in. thick peice of concrete. In any event,if stored in your home, again, the SMOKE may be the most dangerous component. For charging, I think the safest way is to have a temperature probe on each Batt. while charging with a LOUD alarm. The Batt. is ALWAYS going to get Hot first, before flameing or smoking. If you use a LIPO bag, you are not going to see a Batt. start to puff or monitor the temp. of the batt. and if something were to happen, yes your fire may be contained but the smoke will get you. Obviously, I'm talking about charging and storage in your HOME, and are worried about it. Hope this post will help someone or at least think more about LIPO safety.

I have been itching to use my compound bow and a sacrificial carbon arrow...

Would love to fully charge a nice fat 6S lipo and shoot it with the bow. I am confident the arrow will penetrate all cells no problem, and being a carbon arrow, it should short the cells.
