The LG HB4 battery wrappers are so hard to accidently rip a little when inserting and removing them from tight mods over time. It's as if they're the actual cell and thete is no wrapper. Yes...they're authentic. People I know got em from all different places with the same benefit. Mooch confuses me with the HB4 and HB6 cells. He once said the HB2s could possibly be the exact same battery but then his tests show the HB6s win out in terms of amperage as far as calling it a 32 amp in his opinion. Also I read HB4 batteries are the regulated box mod users best bet and the voltage doesn't drop off so abruptly as the HB6. The charts clearly show the HB6s are best but I get away with HB4s and cannot tell the difference under 200W. I think the HB4 is a contender and the HB6...is it really much better for 170W vaping on the new tanks and stuff on a Marshall?
