As the electric bikes. Had finished the race fire men with big yellow boots on would point that heat gun at them .but must say the bikes look fantastic
No one I know of cares around here, and no apologies necessary in my book.
Lithium battery fire precautions will apply to any e-bike or e-motorcycle that I know of.
Well I guess you need an external heat source to ignite gasoline. Lithium batteries can go bang on their own. Wouldn't like one of those to go rogue if I was sitting astride it.

Yes, they try to train us that its "not that bad" because obviously if we firefighters say its a nightmare, than the word gets out that these fires cannot be contained or stopped.
Funny thing is in our training it talks about how it can take 200 gallons up to 5000 gallons to fight and extinguish a EV car fire. Lol.
Its almost like saying 100 hp or 11,000 hp, somewhere in there.........something like that.
Which is night and day........for a car that's the difference in 80 mph top speed and 0-60 around 13 seconds, or 375 mph top speed with 1/4 mile times in the mid to upper 3 second range if you can get traction for the majority of the launch
I think at the worst a combustion based vehicle has caused us to use around 1000 gallons at the most that I can ever remember. Normally a few hundred gallons and its out.
Heck I have fought plenty with the front hose, preconnected, or a trash line as we call it and put them out. Our trash line is a 1" so its not the smallest out there by any means, but some of those are 3/4" lines which is pretty small stuff.
There is little to do to fight them, as removing oxygen does nothing. Foam does a bunch of nothing, and can cause stuff to travel or spread in the upper layer of liquid. Lots of water is all we can do, but even with this, if the individual batteries are busted and water mixing in with the internal elements and all that water causing a reaction that creates more fire.
If its not, and the individual cells are mostly in tact(think 18650 batteries) the trick is to cool the battery casing or shell in the areas where it is the hottest to stop thermal, or slow thermal runaway. Then check temperatures for aprox 10 minutes and if it does continue to rapidly climb, cool the untit for another 45 minutes I think it was and continue to check the temps for a while longer, 1-2 hours and if the temperatures continue to go down and stay down it is extinguished. But, they warn that it could reignite even under these conditions with additional thermal runaway.
