Sold at HD for ~ $105 about a week or two ago so not the best deal at $149 but not terrible if you need them now

Thanks. Would personally prefer not to buy from Amazon.

These 3.5ah powerstack batteries are the sweet spot for size vs performance. The 5ah is a brick and the 8ah is the size of a cinder block. I haven gotten hands on the 4ah but I'm guessing it's similar to the 5ah footprint, maybe a little lower in height.

I don't have any Powerstacks, but I have an "older" XR and some of the batteries that recently went on sale at Home Depot (4Ah+6Ah bundle for $107). This won't be super useful for anyone looking to compare against these Powerstacks, but I'll include some size/weight comparison pics (the best I can do anyway) for my batteries in case anyone is considering the lower-cost options.

In the images, the largest is obviously the "newer" 6Ah, the middle is the XR-branded 4Ah and the last one is also one of the "newer" 4Ah. I'm no battery scientist, but it's my understanding that the main differences here are the cell type (18650 for middle vs. 21700 on left & right—hence the difference in length).

I honestly didn't know they made 3.5Ah in any type—I'm assuming incremental Ah ratings are practical now thanks to the pouch cells they're using.

The 2pk of 5AH Powerstacks are/were this same price since 4/1 at Fasteners,out of stock now but why pay the same for less power?

3.5 powerstack is smaller then 4ah powerpack. This is my favorite compact battery. The sweet spot for performance, size, runtime on regular tools. Performance is similar with the edge going to this smaller powerstack but honestly you wont notice that performance difference unless it is side by side

$105 for the 3.5ah PowerStack (2) pack? OR was it the 1.7ah Powerstack (2) Pack?

I almost didn't buy the 3.5 PowerStacks @$105 because there were no comments. Glad I did though. They're a nice mix of power and weight.
