Grounded 787 and Li battery safety

[Bronek]

Found interesting explanation of Lithium battery safety here [url=http://arstechnica.com/business/2013/01/boeings-dreamliner-batteries-inherently-unsafe-and-yours-may-be-too/]Boeing’s Dreamliner batteries “inherently unsafe”[/url] Especially like the interview with Prof. Levi Thompson, although perhaps not enough technical for some tastes.

They charge at 10C, do I read it right?

I don't think so, it says

[COLOR=#263034][FONT=Arial][I]They are very high power batteries, and they charge them to 90 percent (of capacity) in about 70 minutes.[/I]

Thats less than 1C[/FONT][/COLOR]

This is an interesting sentence

[I][COLOR=#263034][FONT=Arial]The batteries selected for the Dreamliner "were very large scale—65 amp-hour batteries which is very, very large," said Allen.


[/FONT][/COLOR][/I][COLOR=#263034][FONT=Arial]You can generate that sort of output from 10 Opti Packs at 22V,

Perhaps if we let the airlines use our Packs once when flying them in we might get free postage ?[/FONT][/COLOR][COLOR=#263034][FONT=Arial][/FONT][/COLOR]

Of course, brain fart :sly:
It's interesting that airlines don't allow lipos on board, but some aircrafts are full of them anyway.
On a side note, battery technology is lagging behind. Volatile, charging takes long and they don't last. I am not talking only about our hobby. If I had a lot of money is be investing in battery r&d, it's going to pay off big time when someone comes up with robust technology.

There is only one solution for the 787's problems.
They need to go Nitro! :biggrin::gnorsi:

They could have a Nitro generator

I think the batts are for when the nitro generator won't start................:hopelessness:
