Please be aware that standard eGo batteries are basically all the same, some have monikers attached to them like "eGo-C" or "eGo-T" but the batteries themelves are the same, in general (usually) a "C" or a "T" or anything after the "eGo" signifies the cartridge/carto that some use on the battery, it is mostly useless in determining the type of battery.
These are the "Mini" batteries, super tiny for stealth vaping!
