euc on fire

As bad it is for the euc community (and my opinion will surely be unpopular), I actually strongly support stricter guidelines on Lithium batteries on board PASSENGER flights.  Perhaps the whole battery industry should switch to LiFePO4 until an even safer alternative comes along.

UPDATE: Okay, I found out that this was actually Linnea Lin's customer in the video. The video is over a year old. Of course it's not her company's fault but IPS's fault. It was a very early model IPS 101 (if she recalls correctly) and the batteries were "wrapped in a paper material". Apparently a LOT of these caught fire. This was the video from the building management that the victim requested as proof to get compensation. Linnea said that IPS has since "corrected this problem".

Wow! :ph34r:!! I hope it is just a case of cheap no-brand batteries and not something that can happen to 'reputable' brands... pretty exciting video though :)  first the literal explosion and then a non-working fire extinguisher..

 

btw. John, the Boeing statement is for commercial shipments of Lithium batteries -- this can be like 120kg of lithium on a pallet.  The batteries on carry-on can be like 320Wh or about 25grams of lithium; this is way less dangerous than a pallet full of packed batteries in the cargo space. How will you feel if you cannot take your laptop on a plane? Or cell-phone? Moreover, most accidents are due to bad batteries, or bad connections, or damaged batteries --  a quality laptop/phone/EUC will have none of those problems. Of course, I might be slightly biased :D

Yeah but euc batteries are much larger than those in mobile phones or laptops.  I think the entire battery industry should switch to safer alternatives (LiFePO4 for now, Solowheel uses it) until an even better alternative comes along.  Look at what this tiny battery can do:

I have seen the GIF version of this video about half a year ago. Not good for electric unicycle industry. I want to believe that is just a cheap product with a cheap battery set rather than a product from a well known brand.

Apparently if you bought a firewheel and this should happen accordingly I suppose. Can someone name the brand of this electric unicycle by checking the video closely?

I second that! And even if our opinion will be unpopular, there is no alternative to making passenger flights as safe as possible. 

And I can see already the pilots of cargo flights (and the Unions come to that) asking the question why similar measures should not be introduced to cargo planes as well!

This was going viral among the euc groups on FB in the last 12 hours.
First appearing in a FB page then to our sister group:

Sorry for being sceptic, but that video looks like it has been set up. :P The guy rides around the corner directly in the view of the camera, then the EUC explodes just as he's about to get off it and conveniently rolls outside of the camera view... Both extinguishers are on the floor? Is that how they are kept usually? Not wall mounted, the maintenance people or whoever just place them on the floors around the building? ;) 

Real or not video, the safety of Li-Ion -batteries is always a concern, although that should not happen unless the cells are punctured, overcharged a lot or otherwise "misused" or contain too much contaminants to cause a powerful internal shortcut.

As for safe Li-Ion, Lithium-Titanate is probably even safer than LiFePo, but has really low nominal voltage (typical Li-Ion = 3.6-3.7V, LiFePo = 3.2-3.3V, Li-Titanate = 2.4V), so would need lots of cells for a wheel. Or the Tadiran Military Spec Lithium Metal Oxide (undisclosed chemistry) -cells or the high temperature difference version of their Lithium-Thionyl-Chloride -cells. All of these are expensive options though.

Just wanted to point out that it looks like Solowheel does not use LiFePo4 anymore. They advertise XTreme and the S300 Classic both have Sony VC3-cells, which are not LifePo.
