Flat top or Button top

[JMLuck66]

Flat top or Button to batteries. I use an Innokin SVD and use either an 18650 or sometimes stacked 18350 batteries. I have no problems using either. I rotate them when charging. Does it matter to use flat top or button top. My batteries are button top.

The only consideration for button vs flat is generally size - some mods have very little wiggle room and require the intended form factor (I have a chi you mech mod with a kick that really wants me to use flat tops, for example). The SVD, however, telescopes, and so fit is assured no matter which style you use.

It doesn't matter which one you use in the SVD due to it being a telescoping mod, though out of the two, I prefer flat-top over button-top batteries.
