I have been using Samsung 25 flat tops and AW button tops. They are about 4 years old now and still seem to be ok but I would like to replace them.
Unfortunately there is very little availability. I actually need button top batteries now and I can't find any high discharge ones.
I am an old school vaper using a protank4, vaping at max 23 watts on a .5 to .6 ohm coil with a single 18650, so it's a pretty tame setup.
Can I use one of the high capacity low drain batteries?
Very limited availability. Which 18650 will do?
