A LOOK INSIDE DEWALT 4AH BATTERY

Starting the topic since this is inevitable. I will post pics as soon as I get one.

These can be had on ebay from UK for about $180 shipped. I'm 99% sure the cells in those are Samsung INR18650-20Q or -20R (most likely "R" ones). AFAIK you cannot yet buy them in NA. I read somewhere someone said they made the cell walls thinner to insert more active element - what a crock of shit. I think it has to do with material composition and not with material volume. I found Samsung's roadmap powerpoint here, some cells are not listed on their website (the ones they make for Porter Cable end with "L" - not listed)

2Ah per cell, 20 amps max discharge (40A per pack - not bad)
