As the title says, this doesn't really belong here, but I thought it could be interesting to see what can happen if you overcharge li-ion cells.
I don’t know why, but Tesla is famous for having more car battery experience than basically everyone and their battery packs are famous for being the best out there. They’re particularly good at cooling which may also have something to do with it. Also something me flamebuggy didn’t pay attention to. Heat pipes are great for cooling but they actually have to be attached to somethingDoes anyone know why Tesla uses 'canned' cells, surely all that additional metal is unnecessary weight? Surely a larger form factor arrangement would be more efficient and lighter.
lI actually watch one of those. The one with the Disney car. The thing is from the 1930’s for god sake and was designed for golf cart batteries. The guy dumped TWO Tesla battery packs into it without modifying the thing much simply because there was room. I was predicting this one. You do not mix pre and post li-ion technologies without thoroughly exploring the entire electrical system. He didn’t.
I think it's just to bridge the time until they have their own battery factory. They wouldn't have any batteries to put in cars if they waited for that to be finished.Does anyone know why Tesla uses 'canned' cells, surely all that additional metal is unnecessary weight?
I thought their Gigafactory is already up and running. It’s going to be much larger still, but it’s producing battery packs for Tesla cars right now, I’m pretty sure about that.I think it's just to bridge the time until they have their own battery factory.

Personally I think the can weight is less of a problem than the wasted space inside a 18650/2X700 pack.
What's the weight of a can in comparison to the entrails? A LGHG2 weighs 49g all in all, I would assume the can is less than 5% (at max) of that, times 7000 would be about 17kg - not that much weight, that's around the weight of a spare tire, and I consider that the upper bound of the total can weight.
