The Panasonic protected cells and many others are longer and a tad thicker
But the general consensus seems to be anything from
18 - 19 mm diameter
65 - 71 mm length
Are named 18650 since people would probably get confused and well I really like being able to explain to people “Tesla uses these 18650 cells, they pack quite the punch” since people get it then. And I like doing this even while holding a protected cell so just stick with it lol
I don’t really see the point.
When you have the battery out, isn’t it easier to just put it in the charger, than fiddle with these tiny usb connectors that are not made to withstand hundreds of plugs/unplugs anyway?
No indication of charge and extra long battery that won’t fit anywhere as a “bonus”.
The big plus (for me that is, ignorng Brinyte stating it should not be done) is the fact that I can charge them with 1000mA (a normal charger) AND 750mA (the build in charger) to have a total of 1750mA thus much faster charging.
Another really big plus is the fct that I do not need a charger in the car. I have a little car adapter for charging of phones and tablets and an inverter to charge notebooks and that too has a USB out.
These can be used with the USB cable already in the car, so as a matter of fact the Brinyte cells hav given me more spac in the glove compartment :+1:
