Its 3mm difference, springs will take that up.
From everything I've read 20700's really aren't any better than the latest generation of 18650's, eg Sony vtc6
Have a look at what Mooch says & draw your own conclusions.True! Even if it's 5 mm, it should fit. I stay away from the 20700 for the time being. Not enough benefits to justify the price difference.
Actually the Sanyo NCR20700A SKU 6992000 look impressive in the specs if you vape over 10 amps... They have a 30 amp CDR and a capacity of 3100 mAh. If under 10 amps the Sanyo NCR20700B SKU 6992100 would be a better alternative for the "staying power" of 4000 mAh.
In comparing an 18650 vr 20700 the closest we can get right now is the Sony VTC5A (25 amp CDR @ 2500 mAh) So, you're gaining an extra 5 amps on the continuous discharge rating and 600 mAh in run time... Is it worth it for the size increase??? Probably not for most.
The better option will be the 21700 cell Like the Samsung 30T (40A CDR @ 3100 mAh) that Mooch says: "is an incredible performer, running over 20% longer at 30A continuous than the Sanyo NCR20700A thanks to its incredibly low internal resistance of 10-12 mOhms. This low internal resistance reduces voltage sag, letting the 30T run for longer before the voltage drops too far."
TL/DR...The 20700's don't bring much more to the table except size and It'll be a while before we see the 21700 cells in the vaping market. But, if updating a device. Get one that'll take both... IMO it's really only beneficial for a single cell device and in particular, a mech user that likes to build super low. :)
Living is the only thing worth dying for...
