It's just a matter of whether or not you believe them. I'm giving them the benefit of the doubt because I have no reason not to. eFest wasn't the only company selling "35A" 2500mAh batteries that were actually 35 pulse and 20 continuous, so I don't know why they get so much shit for it. It wasn't like they were trying to hide the fact that they were rewrapping LG batteries (which many vendors advertised as 35A as well) so they're still good by me. And as I said before, they claimed to have learned their lesson, and that all their new batteries are not rewraps.
The amp limit spec is going to be determined by the marketing department anyway. For example, the engineers may say it's 25A continuous, but they test it and find that the battery doesn't start to heat up until it's drawing more than 38A. So they call it a Maximum Continuous Discharge Rate and market it as a 38A continuous. Whether you agree with that practice or not is irrelevant because it actually makes sense from a business perspective. The engineers want to play it safe with conservative numbers, and marketing wants to stretch that number to increase sales. That isn't an eFest-exclusive practice.
That being said, I've used the eFest 38A 2100mAh at upwards of 30A without issue. Granted, the voltage drop was probably enough to drop the current draw to less than that, but it makes me feel better to have more headroom. When you start hearing stories about batteries going nuclear at below the CDR, then there will be something to worry about. For myself and others I know, we've never had a problem with eFest. In fact, they've all performed very well and don't heat up at all with the builds we use.
I'm not trashing your choice of battery, or saying that you should start using eFest. Use whatever works for you. I'm just saying that eFest catches a lot of flak and I don't think it's necessarily deserved. They seem like a legit company that may have made mistakes, but are genuinely trying to improve and push the market, and they seem to take customer feedback seriously. That's more than I can say for the majority of e-cig manufacturers out there.
