Hello all,
I just committed an inadvertent blunder that I thought I'd share in case it might help others.
I ordered a couple of 18650 Lithium Ion batteries for a robot vehicle that I'm building. I saw that these batteries were "protected" at the using note (content source from blog) that I didn't understand well, that is, circuit protection function, but did not consider the implication - after all an 18650 has a standard dimension as the name suggests, right? Well, it turns out that the protection circuit increases the length of the battery - in this instance by slightly more than 3 mm and I'd probably have to destroy the battery holder to get them to fit.
Oh well, I can probably use these in a flashlight. I'll need to order new unprotected ones for the robot. I'm a little surprised that the clips in the battery holder don't give a little more.

i have never seen them like that... do you have a batteries plus close by? you might be able to get the standard lithium batteries there... best of luck
Re: 18650 Using Issue for Beginner
so you are saying 18653 would be closer to reality?, that's more than a tenth of an inch. I suppose a new battery box is not in the budget.

Some of 18650's also have a built in mini usb charging port.. My flashlight has this type of battery.
also as well, they do make protected cell types of the 18650's, which is a fuse in them, but once that pops, the cell is useless..
Many Vape Batteries have this.

AND, be very careful measuring the length of lithium cells with metal calipers!
