these are good batteries but they are very expensive (mind you, no protected NCR18650GA batteries are cheap). i bought this for my nitecore p30 flashlight because at the time i didn't know much and wanted to be sure they fit. works well but i've since found cheaper alternatives.

Good battery. Should be an improvement over the NL189 previously used. Don't work with the HC33 at full brightness, maybe due to the integrated protection circuit.
