KICK + 4Nine = Bad MoJo
BE VERY CAREFUL!!!

You picked one of the touchiest, though excellent performing, mods to get your feet wet with.
4Nine will only take a:
18350+kick in 18500 mode
18500+kick in 18650 mode
In both cases you still have to worry about Battery Fit.

Top is Hybrid=no adjustments
Switch is Floating Magnet/battery design=space limited

To much space=poor to no switch function
To little Space= Auto firing

what's the threading on the 4nine?
if it uses m21x1 then a chiyou kick ring will work to use 18650+kick

Yes I understand about over discharging etc just wondering if the batteries last about the same time span.

If the drain is the same, yes.
If not YMMV.

Your battery life will depend on your build.

A mech with a kick will have a shorter battery life than a mech without.
The buck/ boost circuitry of the kick will draw power to maintain the setting.
This gives a consistent power level until battery falls below the threshold.

Without a kick the vape just gets weaker as battery loses charge.
You will notice a change
That's when you swap batteries and recharge.

While your comments seem logical, a Kicked Mod will often last much longer with a smoother vape than an standard Mod.
Kick does not draw power when not active. The Mods switch has broken the circuit. The kick is physically adjusted, not electronically.
