I would point something out.
There is no law that says you have to use just one. That bat is going to come off the charger at 4.2v, and many people will find a LR carto a bit much. However after a few hours they will find the LR carto just right. If that's the case for you, why not have both SR and LR cartos so that you can swap them out.
The neat thing about
vaping is that there is no right or wrong when it comes to prefference.
