Re: Only 96 batteries
"Why is the mileage comparison irrelevant - that's why the 2 Gallons was being questioned as I read it..."
I was actually supporting your 2 gallon estimate, just with a caveat that in order to assess safety, we have to compare thermal energy of burning Li-ion battery with thermal energy of burning fuel. Mileage comparison is misleading because electric car gets its mileage from the stored electrical energy, but ordinary car from thermal energy. Apples and oranges.
So yes, previous poster was wrong to challenge your claim on the basis of mileage.
There are of course other aspects besides available combustion energy that are affecting the burning process - especially the speed and violence of it. For one, fuel needs sufficient quantity of oxygen for burning, whereas Li-Ion cells carry their own oxidiser. Skews the comparison quite a bit.
