Custom 10-Cell 21V MAX Battery Compatible with DeWalt-Style Power Tools

Developed as an aftermarket power source, this 21V MAX rechargeable lithium-ion battery pack is compatible with selected DeWalt-style cordless tool interfaces. It is intended for angle grinders, impact wrenches and high-load tools. Voltage, capacity and cell configuration must be confirmed for the selected SKU before production. The custom ten-cell configuration is intended for higher-capacity applications; confirm series-parallel layout, nominal voltage and charger settings. An integrated protection circuit helps manage overcharge, over-discharge, overcurrent and short-circuit conditions during normal use.

For OEM, wholesale and private-label projects, housing color, product labels and packaging can be reviewed according to order requirements. Confirm the original battery code, connector, charger, voltage and physical fit before purchasing. Brand names and model numbers are used only to identify compatibility.
