Our take on the DeWalt 20V to Kobalt 24V Battery Adapter

This adapter lets a DeWalt 20V MAX lithium-ion battery power Kobalt 24V cordless tools from Lowe's. A DC-DC converter steps the battery's 20V up to the tool's 24V, and a built-in BMS adds protection electronics. It uses an ABS battery interface, a 3D-printed ABS tool socket and copper terminals, rated 55A continuous and 100A peak. It suits owners already on the DeWalt 20V platform who want to run a Kobalt tool without buying a second battery and charger.

About the DeWalt 20V to Kobalt 24V Battery Adapter

This adapter lets DeWalt 20V MAX lithium-ion batteries power Kobalt 24V cordless tools. A built-in DC-DC converter steps the battery's 20V up to the tool's 24V, so the tool runs as it would on its own battery. It works in one direction only: DeWalt batteries powering Kobalt tools.

The battery interface is injection-molded ABS, and the tool socket is 3D-printed ABS for a close fit. The contacts are pure copper. A built-in battery management system (BMS) cuts power before the battery is drained too far.

The adapter only powers tools. It cannot charge batteries and must never be connected to a charger. Remove the battery from the adapter before charging, and charge it on the original charger made for the DeWalt 20V MAX battery. Use a battery of at least 3 Ah, with 4 Ah or more preferred, because a higher-voltage tool draws harder on the battery. Some Kobalt 24V angle grinders may need a short restart because of the delayed output protection: switch the tool on briefly, wait about 3 seconds, then switch it on again. Most drill-style tools do not need this step.
