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

So ,despite the heading, this item gets 5 starts. I bought 2 of these batteries about 2 months ago. They both worked as expected out the box. After 1 charge, I noticed one of the battery's fuel guage stopped working, but the battery was still powering my devices. I was past the 30-day return window with Amazon, so I emailed Dewalt and they immediately got another item shipped to me (even though I told them the battery was still functional despite the fuel guage failure). About another 2 weeks passed and the faulty battery finally died. After doing some research, this apparently is a widely reported issue specific to the 5Ah PowerStack batteries It's a great battery, size is good is you want a step down from the 5Ah XR, and at under $100 on Amazon it's sure worth it. Just keep in mind that it might fail, but Dewalt shouldn't have any issues replacing it if it does. They just asked me for the inv. which I downloadednfrom Amazon, and that was it. So 5 starts because it's a great battery. Though I had issues with 1 of the 2 I bought, it was a hassle-free replacement.

Battery dated late 2025. Charges quickly and retains power working all day.

Probably replacing all my batteries with these on my next rotation. Runs my saws stronger than I expected out of a 5ah for sure. Charger is a charger. It charges. Price isn't bad. It's heavier than I'd expect for the size, but still way smaller than my flex volts.

Genuine Dewalt power stack kit. Brand new, sealed in the box. Came with a 2025 Powerstack battery. It’s great to have another new 4amp battery charger. I have no issues; this was an excellent deal for the price.

Ordered this battery on Amazon resale. It worked great on my dewaltz leafblower for 2 sessions and now it is bugging. It keeps cutting after pressing power on trigger for a more than 5 seconds. I complained both to Dewaltz support and to a reseller'both just refused to talk and solve issue with me. Bad purchase. Do not recommend

I have 12v DeWalt drill for over 10 years - still working great. I recently decided to upgrade to the 20v Atomic with the smallest available PowerStack (this item). Yes the thing is nearly indestructible. But it feels twice the weight of my little 12v. I must say the 12v is plenty strong for most household use. So now my 12v remains in the kitchen drawer for whatever new furniture assembly comes through the door. My 20v Atomic is in the garage for hole saws, spade bits and hardwoods. No complaints, just FYI

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.

I love DEWALT and all its tools. This battery works for multiple tools and having an extra battery ready to go is a must!

Ya le di buen uso y si dura mucho mas que las normales, te da poco mas potencia a las máquinas y no es gigante como la flexvolt . Buena inversión si usas máquinas que piden potencia y uso continuo (como sierra recíproca o esmeril).

I love these Powerstack, they definitely last longer than the regular battery packs

Excelente producto, llevo usándolo en cortes de madera, MDF y MDF enchapado. Creo que es bien sabido que la marca corresponde con la calidad de sus productos. Estoy muy satisfecho.

after using powerstack 5ah and 1.7ah i will never buy another XR battery. way more power and lasts way longer. well worth the price differance. also they are a must have for tools like grinders, saws, and the die grinder

La batería y el cargador llegaron un día antes y en su estuche original. Ambos funcionan perfectamente, la batería excelente para el uso que le doy. Con este paquete sale más barata la batería que comprarla sola. Recomiendo aprovechar esta oferta. El vendedor bastante confiable.
