Protected batteries have internal circuitry that protects the battery against common dangers, such as overcharge, over discharge, short circuit/over current, and temperature.

Unprotected batteries without this circuitry will be cheaper and can have a higher capacity and higher current capability. If you are vaping then a regulated mod will provide the protection provided by a protected battery and will make use of the unprotected batteries higher current capability.
