DeWalt's 4Ah Powerpack batteries are being framed as a premium 20V MAX XR option with strong output and better durability than Powerstack's pouch design. The tabless cylindrical cells are described as easier to service and likely more durable, while still delivering similar power, though the Powerstack shape keeps the edge on size and weight. The main drawback is price, since the pack is seen as expensive per amp-hour and the coupon reportedly does not work. It is a solid fit if you want DeWalt's newer high-end battery format and can justify the cost.

Common Questions (5)

  • Yes. It is described as the lowest recent price seen for 4Ah Powerpack/Powerstack packs, with some saying it is unlikely to go lower unless it is clearance. The deal is also viewed as premium-priced because these packs use higher-end 21700 cells.

  • Powerpack batteries use tabless cylindrical cells, while Powerstack batteries use pouch cells. Powerpacks are expected to be more durable and easier to service, while Powerstack packs are smaller and lighter for the same capacity.

  • No. The coupon code does not work on this offer.

  • Yes. Powerpack batteries are considered easier to service yourself if they need repair, which is a practical advantage over Powerstack packs.

  • Yes. A standard 6Ah or 8Ah DeWalt battery will generally run longer, while the 4Ah Powerpack may deliver a bit more output under heavy loads.

Stop paying more than $10 per ah! DeWalt will never lower their prices!
I don't care what type of tech it is either! If you feel good that you got scammed.... so be it!

I think this is the lowest price we've seen on the 4ah powerstacks in the latest tranche of sales. I doubt you'll find them lower unless on clearance. If you're lucky enough to be new to woot, $85 for these is incredible

I can't get more than $10/ah selling regular Dewalt batteries on FB marketplace, but I've never seen Powerstacks near this price point.

Our community has rated this post as helpful. If you agree, why not thank

I almost bit on this until I realized that these are power pack batteries, not the "power stack" batteries. This is still a good deal but not a great deal.

What's the difference between these 4Ah and the other 4Ah slim packs. Looks the same, just different branding with XR?

Curious why you say that? The Powerpack's have the tabless cylindrical batteries and the Powerstack have the pouch batteries. The cylindrical are going to be more durable. Power output will be similar. Powerstack will have the edge on size and weight.

I personally prefer these 4Ah Powerpacks over everything else I have.

Agreed, and a PowerPACK battery is easier to service yourself if need be. I understand PowerSTACK batteries are the future, it's repairing them yourself the main issue for me. Hopefully as the generations progress in their tech, that will change.

I personally think the Powerstacks are a scam! Just another form factor for the worse to do the same as the tried and true 18650/21700 cells. Proven swelling issues on pouch batteries is not a good idea in any tool lineup, so why do it?It's just another DeWalt scam to fool the dumbasses.
4ah Powerpacks use the tabless 21700 cells with 1 row of 5 for a total of 5.
While a standard/xr/max 6ah battery uses 21700 cells, but 2 rows of 5 for a total of 10.
Powerpack will output a bit better under heavy loads, but a standard 6ah or 8ah battery will do the same and the 6ah run way longer than the 4ah Powepack.
The two 8ah comparison ??? both use 21700 cells, same capacity, same runtime basically.
I would say it comes down to price! lowest that I've seen is from a 2pk.
dcb208 - $84ea vs dcb2108 - $91ea
Would I bite on the 2108 for $91 ? Only if I had a need for it, or a near future need for it.
I still have brand new 6ah batteries with 6amp charger kits sitting in their boxes, just wasting away on their 3 year warranty, but the $65 deal was too much to resist.

If these are populated with premium 21700's, that means $10 per cell. Seems like premium price to me.

I believe that dewalt is actually abandoning the powerstack experiment, and moving forward with powerpack/tabless as their top end batteries. Milwaukee and everyone else skipped over pouch cells entirely and went straight to tabless cylinders.

Yes, powerpack batteries are more expensive. There's good reason for that. If you want to pay $10/ah, just buy the regular old 20V batteries and call it a day.
