The Golisi 18350 Battery comes in a pack of two. Additionally, each vape battery has a maximum CDR (continuous discharge rating) of 10A, which for a 18350 battery size is above the average.
Also, each Golisi S11 battery has a capacity of 1,100mAh. Although it's not a huge capacity (as expected), but it's ideal for those smaller setups that utilize this battery size. Devices such as the SXK Bantam Box Revision would work perfectly with a set up these Golisi S11 18350 batteries.
