I already have 2 sigelei zmax mini's that came with extensions and I used to only use them in 18350 mode but after reading some comments here, I tried stacking batteries and I love them even more! I have panic attacks thinking of them ever dying. That's one of the reasons I'm tempted to click the buy button.
I wonder if my current ss extensions are compatable with the aluminum zmax mini's?
Yeah stacking turns it into a new device. Night and day in the power category. Breaths new life into it and extends its power capabilities and battery longevity. I still can't believe I'm using my original v3. It's the only mod I have, 1 year no backup needed; this thing just doesn't fail or falter. I never worry about it failing on me.
I wanted more power but I didn't have to buy a new mod just a pair of batteries and now I'm up to 20-24w in voltage mode.
