We do not have a 510 cartridge option. One reason for this is that its important in those setups to make sure that the battery is properly paired to the heating element in the cartridge. Mixing and matching batteries and cartridges is pretty common, but when that happens an unpaired device can result in overheating of the coil, which can lead to incineration/combustion as opposed to vaporization, potentially releasing carcinogens. We chose to use a self-contained device that includes both the battery and the heating element to ensure that the vaporizing experience is completely consistent every time without any unintended side-effects.
