i just got this 26650 hades battery body, then was reading the papers that came with it and it sates, " using the 26650 battery, screw out the top cap reverse side, put the negative pole of 26650 battery into the battery tube first, then screw the top cap and tube together tightly" unless i've always been drunk and high on nic, i've always put the positive pole "facing up" in my battery tubes. Am i misunderstanding something here ? or does the negative pole face down in these particular battery tubes
