This adapter lets RIDGID 18V lithium-ion batteries run Hercules 20V cordless tools, so one battery platform covers both brands. It uses an injection-molded ABS housing, copper terminals and 5 mm² wiring rated for 40A continuous and 80A peak for up to two seconds, about 720W at 18V nominal. Built-in battery management electronics cut power before the battery is over-drained. It suits owners already on RIDGID batteries who want to add Hercules tools without a second charger and battery set.

This adapter lets RIDGID 18V lithium-ion batteries power Hercules 20V cordless tools. It works in one direction only: RIDGID batteries powering Hercules tools. It is made for the RIDGID 18V batteries sold at Home Depot and the Hercules 20V tools sold at Harbor Freight.
The housing is injection-molded ABS, and the terminals are copper. Internal wiring is 5 mm². The adapter has a built-in battery management system (BMS) that provides battery protection.
The adapter only powers tools. It cannot charge RIDGID or Hercules 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 RIDGID 18V battery.
