Raz's Monster Pro battery fire

[Flying W 551]

It's always sad to see these things light up. The battery's in my RS don't look any different wrap wise than any other gotway, and gotway has been good too me over the last 2yrs. I'm hoping my house doesn't catch fire in the middle of the night! 

It's too bad the evidence always burns up so we never really know. When this happened to a few V10s it came down to keeping the moisture out and better casings. 

Would it be a good idea to add one more wrap to the batteries in our wheels, more goop where the cables come out too? It's not like there is much room to add very much to the existing packs.

An explanation was offered: metal debris inside the shell dislodged by (riding) causing shorting of the control board. Sounded plausible, anyway.

where did this explanation come from? there were no debris as I had open the wheel up prior to this and did not see anything unusual.

I'll just leave this here:

It was just more internet speculation; but an important possibility to keep in mind. All it would take is one loose wire cutting, screw, washer, or metal shaving (from the heatsink) to bridge exposed connections on the board and get things started...

p.s.- love your content @Hsiang. Holding a DSLR on a pole to take selfie video (instead of an action cam) to tighten depth of field... dedication!

As discussed below, bags & mats would be useful for picking up a burning battery in order to 'throw it outside'... but if you're not home, non-rigid insulating devices are unlikely to help

Uh the other post made it sound like this was the reason not just speculation and if Hsiang didn't correct you, some would of  taken that as fact! 

There too many armchair specialists here and not enough actual specialists. Where the mechanical, electrical engineers, mechanics etc to give us some insight not just some average Joe who can google and has read a few buzz feed posts that just have a elementary understanding.

We’re all speculate, but let’s remember to formulate it so it’s clear. ”I think it might be” etc.

This also applies to technical data, I see so much misinformation, and it just spreads warping further and further from the truth. Lets not state as facts things one aren't entirely sure of.

As much as I don’t care what people believe or think, misinformation is dangerous, in a small scale (the guy who’s EUC goes up in flames because he heard something about charging to 80%) and at a large scale where people are turning anti science and toward populism, undermining democracy.

Not long ago I heard a YouTuber claim that the Sherman was now made of carbon fiber. (He heard the keyword carbon fiber regarding the motor cable sleeves) Be responsible and don’t do that, with great power comes great responsibility etc.

Educate yourself, and have healthy amount of doubt in everything and everyone.

It still surprises me how much people blindly / lazily believe what they hear on YouTube from "experts" / "veterans". YouTube just means they have a camera and know a little bit about how to edit, that is all.
