Q: If you’re not interested in spilling, how high do normally fill a cup?
Now, if YOU spill some water, it’s not the end of the world, but if you overcharge ME (your battery), it’s REALLY not good.
Q: When a waiter is filling your cup, when do you “say when”?

around 80%!
This should help you understand why we quote our DC Fast Charger times up to the 80% level. (It wouldn’t be wise to rapidly charge all the way to 100% now, would it?)
