Found this about the Ijust2 kit.
Eleaf Ijust 2 Review - Vape Reviews You Can Trust
And this is included in the text/review of the KIT.
'The Eleaf iJust 2 kit comes with their standard 0.3ohm coil installed. They also have 0.5ohm and 0.15 Ni200 coils available separately if you like a tighter and cooler draw. '
NEVER EVER use NI200 coil with a non Temperature control mod.

With that minirant over.
Looks like the mod will handle down to at least a .3 resistance coil.
