Actually I do have one more hint:
This manufacturer also has batteries branded in their name and Mooch has tested some of them.
In fact, they made a dual battery mod that that uses an uncommon battery size that's hard to find other than their brand. And apparently, according to mooch, it was basically a gimmick battery. This was an obvious attempt to make a mod where the user would be beholden to them to keep it running, like a proprietary battery. I would go as far as to say, from my own perception, that this manufacturer has a history of gimmicky products - like coil heads with LED lights on them.
