According to the battery on the website you linked, the unit is similar to a EGO with a 510 connection. Looks like a 650mah, so you can either go with a 510 standard or LR carto. Standard will give you a cooler vapor with a longer draw time, LR will give you a warmer vapor, more vapor, you dont have to draw on it as long and usually a stronger
throat hit. The downfall of using a LR is that it drains your battery faster. I, personally only
vape on LR atty's and cartos.
