The screwdriver, janty stick and other mods use unprotected as well...........if your charger has overprotection it is very difficult to vape to the point of overdischarging and if you do it will simply not recharge.
the 10440 is the only battery that will fit in mods that small. I have the same batts in my passthru . So it is not a real big deal IMO
the charger is the most important part
