I'm trying to figure out if the new 4Ah batteries are actually better than the 5Ah ones. I saw a deal at Lowe's where the 4Ah ones are priced at $199 and the 5Ah at $299, but with the 5Ah you get two free tools instead of just one. Is it worth saving the $100 to go for the 4Ah, or should I just stick with the 5Ah?

From what I've read, the 4Ah batteries seem to have a slight edge over the older 5Ah versions in terms of power delivery. Testing has shown that even though the 5Ah should have a higher discharge rate, the new 4Ah batteries perform better due to improved internal resistance. Just keep in mind there is a small difference in capacity between them.
So, based on that, which deal would you recommend? Getting the 2 tools with the 5Ah or just going for the 4Ah with only one tool?
