The DeWALT DCBP520C 20V MAX POWERSTACK 5.0Ah Starter Kit is a battery and charger kit for contractors, remodelers and serious DIYers running DeWALT 20V MAX cordless tools. This is a cordless tool battery starter kit designed to power DeWALT 20V MAX drills, impact drivers, saws, grinders and other tools. Model Number DCBP520C includes one POWERSTACK 5.0Ah battery and one 12V/20V MAX charger.

DeWALT calls the POWERSTACK 5.0Ah its most powerful battery in its class. Instead of the cylindrical cells inside a conventional pack, it uses stacked pouch cells. DeWALT rates it at 50% more power than the DeWALT DCB205 20V MAX 5.0Ah battery, along with 50% more work per charge and up to 2X the lifespan, measured in charge cycles. DeWALT also rates it as 50% more efficient, making it the company's most efficient battery in its class.

What that means on the job: a high-draw tool like a circular saw, grinder or large hammer drill is less likely to bog down in a heavy cut, and the battery stays in your rotation longer before it needs replacing. DeWALT also describes the pack as compact for its capacity, which helps tool balance overhead or in tight spaces.

The build is jobsite-ready. An impact-resistant, overmolded rubber base takes the hits that come with daily use, and because it's non-marring, it's easier on finished floors, cabinets and countertops when you set a tool down. The 3-LED fuel gauge gives a quick read on remaining charge.

The included charger is the DeWALT DCB1104 12V/20V MAX 4 Amp charger, which handles both DeWALT 12V MAX and 20V MAX lithium-ion batteries. That makes this kit a practical way to turn a bare tool into a working tool, or to add a second battery and charging station to an existing setup.

Compatibility is straightforward. The POWERSTACK 5.0Ah battery works with all DeWALT 20V MAX tools and chargers, so it drops into your existing lineup without changing platforms.

Who should buy it? Anyone who just bought a bare DeWALT 20V MAX drill, driver or saw and needs a battery and charger, and pros who want stronger output than a standard 5.0Ah pack. Remodelers, carpenters, electricians and maintenance techs who move tool to tool all day get the most out of the extra power and lifespan. Already have a charger? The DeWALT DCBP520 20V MAX POWERSTACK 5.0Ah battery is the same pack on its own.

The DeWALT DCBP520C 20V MAX POWERSTACK 5.0Ah Starter Kit Is the Upgrade Your Bare Tool Deserves

If you're buying a 5.0Ah pack and charger anyway, POWERSTACK is the version to get.

• Who it's for: New bare-tool owners and DeWALT 20V MAX users adding a battery and charger.
• Why it stands out: Pouch-cell output DeWALT rates at 50% more power and up to 2X lifespan versus its standard 5.0Ah pack.
• Worth knowing: One battery only. If you run tools all day, a second POWERSTACK pack keeps one charging while the other works.
