BE CAREFULL!!!!!!!!!!!!

I talked to the ROAR Tech Director about it over the winter. I think one of the biggest factors is they dont have the bandwidth, tools, of knowledge internal to the organization to determine what is and isnt safe. Its not like its a paying job and they are making a load of money. They are just racers like you and I that stepped up to volunteer to help. Im not a big fan of ROAR but at the same time I see his points and it gives me a different perspective.

Well if an element is inherently dangerous, such as LITHIUM perhaps an alternative should be sought after. Whether it is in the protective case encasing the cells or if it in fact means using a different element. By posting all of this I was attempting to educate people on WHY lithium (LiPo) is dangerous....because the chemical itself is dangerous. Same goes for Magnesium and any of the other volatile elements that can be used.
I'm all for longer run times and ease of use such as what Lipo has introduced but perhaps we can work towards the same benefits with a safer cell...
Hope that answers your question.

A123 has flat out said no flames, no explosions. Orion has almost said the same. Technology is definitely getting to an acceptable safety level in these packs. It's just hasn't proved the test of time yet.

An unsafe element does not necessarily remain unsafe when combined in certain ways with other elements. You posted the effects of pure lithium, not the effects of lithium in the form that we use. Sodium and chlorine have some pretty nasty effects but I sure can't live without them to make my food taste bearable. Technology can alter the volatility of lithium to make safer packs.

This is true, however Lithium is a highly combustible element. Unlike Sodium and Chlorine that are used to make table salt. Neither of those base elements are highly volatile in their "normal" state. I agree that when mixed with another element you can reduce the volatility, however you are starting from a dangerous base. This is simply my opinion...
