Why do we like this deal?
If you’re a DeWalt tool user, you’re either the type of person who has a bucket of batteries in your workshop or are jealous of those who have batteries. No matter which category you fall into, DeWalt battery bundles are a great way to fill any gaps in your collection. And, right now, thanks to Amazon Prime Day, there’s a deal on a 20V 4-pack with a practically unheard-of power-to-price ratio that every DeWalt user needs to know about.
DeWalt 20V Max 4Ah, 2Ah Battery 4 Pack (DCB324-4) is now $129. Regular men’s journal Readers may remember its 5Ah/2Ah version which reached $194 about a month ago. Although this deal is “only” 28% off, you’ll quickly see that it’s a much better deal mathematically. This set is priced at which it has no proper competitor since July 2024.

What shoppers need to know
- Equipment Series: dewalt 20v ma
- Battery included: 2 4Ah batteries, 2 2Ah batteries
- power gauge: led light bar
This set gives you a total of 240 watt-hours of energy. Still, you’re only paying $129 for it, a price of about 50 cents per watt-hour. This is a price point rarely seen, especially for a company like DeWalt. When the price of the EGO Power+ battery reached the same watt-hour level earlier this year, it became the bargain of the moment. Now, we’re getting a chance at the same deal with DeWalt.
Plus, it has a really good split between small and medium-sized batteries. In particular, 2Ah batteries are very versatile because they have a thin back and weigh only a pound. Meanwhile, the 4Ah offers a balanced weight-to-power ratio that helps keep devices balanced but also charging for extended periods.

what shoppers are saying
After thousands of ratings, these battery packs still hold a 4.8-star rating due to their overall simplicity of use. One shopper noted that “they charge really quickly and last quite a while,” while another commented on how they “flip-flop” through pairs of 4Ah and 2Ah batteries: “I’m able to consistently swap out a dead battery for a freshly charged one with no downtime.”
The price of the DeWalt 20V Max 4Ah, 2Ah Battery 4 Pack (DCB324-4) has dropped to $129, a special price that coincides with Amazon Prime Day. This sale period ends on Friday, June 26, after which the deal will likely expire. If you want to get it at this price then make sure to purchase by that time. You probably won’t see anything even close to this again until the holidays.
