Difference between 18650 and 20700

[Iftkhar Rashid]

Ordered a Nitecore i4 battery charger.
I know it will take the 18650's, will it take 20700?
What's the difference?

Thinking about picking up the iJoy avenger and I notice it's supplied with 20700's.

Cheers

Yeah the nitecore will charge 20700 batteries, the difference is the size, 18650 is 65mm long and 18mm wide, 20700, is 70mm long and 20mm wide, there can also be a difference in run time and amp limit, but that all depends on what make and model the battery is...

They're a bit tight, but they do go in. Just tried one in an i4 I don't use.
