DEWALT Powerstack 20V MAX Battery Starter Kit, Rechargeable, 5Ah, Lithium Ion (DCBP520C)

The first one they sent was defective. We got a replacement within 4 days from Amazon. The replacement works perfectly. A little heavier than I expected but perfect for our needs.

Idk if these batteries are cheaper made or what but I've gotten 2 bad power stack 5ah batteries in a row. Both batteries the fuel guage quit working. The first quit charging all together not long after the fuel guage quit. The second one acts up constantly it cuts out over an over. Then it dies way quicker then it should I only run it in a impact driver. It's not like I'm using it on a grinder or Sawzall it shouldn't drain as fast as it does. I've got 6ah batteries that out preform the power stacks by a long shot. These power stack 5ah are more then half the price with a charger on Amazon then anywhere else that sales just the battery without a charger. Something isn't adding up. If the ones in the store weren't 220 dollars I'd buy one to see if it craps out like the other 2 I've gotten thus far. But for now I'll just continue to buy the 6ah batteries I've bought 3 recently and had zero issues with them... time will tell.

Trying Powerstack out in my older (not brushless) 6.5 in circular saw for a deep cut I can tell that his battery delivers more power and the saw is able to power through the material better. Also, in my 20v blower that I use on my driveway after mowing the battery does a much better job powering the blower at full power before stepping down and dyeing rather quickly as opposed to the older XT 5ah battery that would dwindle down over what felt like the last 25% of the battery to much lower levels, the Powerstack went strong then started to drop off at maybe the last 10% or even less. These do cost more and the costs add up but this combo that I am reviewing often has the battery and 5ah charger for less than anywhere else that I have seen. You can always sell the charger if you don't need it or put it in another location where its handy so I think its the way to go to get the Powerstack. Powerstack pack is a little heaver by about 4.2 oz. and though its slightly slimmer (top to bottom) it has a larger footprint by about 1/4 inch wider and 5.8 inch longer across the base. Also, the power stack also has a grippy rubberized bottom that will not slide around like the XR pack with a smooth plastic base. I'm a bit disappointed that the Powerstack is bulkier than I expected but it does a great job delivering power and I look forward to a larger 6ah or 8ah pack in the future.
