Swapped these into my regulated mod and the 25.3A rating gives me plenty of headroom for the wattage I run. The 2547mAh capacity actually lasts me through a full day of chain vaping, which I didn't expect from an 18650.
These hold voltage noticeably better than the cheaper cells I was using before, still reading solid after a full day of chain vaping. The 2547mAh capacity actually lasts me through two tanks instead of one.
