If anything just 20A, I have a set, they work, I personally would not replace them when they die.Well according to the tests the 30Q are actually 20A and not 15A as stated by Samsung, it comes down to whether you trust Mooch's test or not.
Samsung have underrated their batteries before, so no surprise here.
it's actually 20amps per mooch. samsung rates it on the safe side. newer LGs rated out at 18 amps now according to mooch so the 30q would be a better bet.3OQ only 15A, seems to hit a little weak on full charge as compared to HG2, 25R or VTC5.
