I got a pack of these recently too. Love them.
Yes they DO work with regular 510 batteries, and theoreticly the oHms are correct and should not damage or shorten the life of the battery.
BUT, I have not done thorough testing on this, only tried to see if they work (which they do)
I love them at 3.7V. Same as what you described at 6V. I'm still boggled as to why they can be vaped at voltages over 3.7. Any ideas?
Got one going and it's been working for 4 weeks. The vapor is still strong but the draw is getting tighter.
Not bad. I hate to retire it when it's still throwing clouds, but might anyways, and then dissect it.
