Still 4 tons less cargo they can haul, and unlike diesel, those batteries weigh the same regardless of how full they are.
Not exactly. Battery weight changes based on charge. Try it with a AA or 9V. When it's new, it'll weight more than when it's exhausted. The same goes for these batteries.
“batteries weigh the same regardless of how full they are.”
That’s bothered me since I was kid. You buy a battery and when you throw it away it weighs the same as when you bought it.
A great thing about diesel and gasoline is that they don’t burn without air. Those liquids are very safe when in a tank and even if out in the open will burn only as fast as they can get oxygen.
A lithium battery on the other hand is, worst case, a self contained explosive.
Which is perhaps why FritoLay was the first named beta-tester/customer. Doesn't take much weight to haul a truck filled with Doritos.
Frito-Lay, that’s a helluva heavy load. What’s a semi load of potato chips weigh? 100 lbs?
