The DeWalt DCBP034 is a 20V MAX battery built with stacked pouch cells instead of cylindrical ones. DeWalt rates it at 50% more power than the DCB203 2.0Ah pack in a body about 25% smaller, and it uses a 1.7Ah capacity aimed at high-output draw rather than long runtime. It fits every DeWalt 20V MAX tool and charger. It suits owners who want less weight overhead and in tight spots, or who want more punch from compact tools; anyone chasing all-day runtime should look at a larger pack instead.

Owners rate it well and mostly talk about the extra power and lighter feel in compact tools. The common complaint is runtime: 1.7Ah drains quickly in saws and grinders.
The DEWALT DCBP034 is a 20V MAX POWERSTACK compact battery pack with a 1.7Ah capacity. It uses lithium-ion chemistry and a stacked pouch cell design rather than traditional cylindrical cells. It delivers 50 percent more power than the DEWALT DCB203 battery in a size that is 25 percent smaller, and the number of charge cycles over its lifetime is increased.
The compact, lightweight shape suits work in tight spaces and overhead work, and improves balance and maneuverability. The base is overmolded with non-marring material to resist impact and wear. An LED fuel gauge shows the remaining charge.
The battery is compatible with the DEWALT 20V MAX system and tools.
