Vamped makes batteries for the Vaping community... the competition guys typically look at pulse ratings over continuous ratings... and the pulse ratings of the Vamped cells are for 60 seconds (according to a letter I read on another forum, and can probably relocate if desired). Unless you guys are holding down the firing button for over a minute, on a mechanical mod, I'd say they're a safe 40 amps for your vamping needs.
Vamped cells are not re-wraps of any other batteries on the market, from what I've seen. In fact, the only batteries with identical specs are the purple Efans, which are just a manufacturer "relabel" to get in on the money from the same cells. According to Vamped, they worked with a Chinese manufacturer, and the cells are a proprietary cell. If you look up Efan, their sales website states they are a manufacturer; which means they are likely the people who make the Vamped cells, and are just "relabeling" them as their own. It's a similar story for Imren, but that's another topic.
I've used the purple Efan "relabel" batteries, and I've enjoyed them. The battery life sucks for all day low resistance vaping, but they're definitely quality cells. If you want to give them a try, just know they aren't going to last you very long. On the upside, the spec sheets claim the minimum voltage to discharge them to is 3v, which means you can basically milk these batteries for a while longer than most. Do that at your own risk, but I've not had a problem with killing them prematurely after constantly discharging them below 3.5v before recharging.
Meh, just my two cents.
