{"product_id":"black-and-decker-20v-to-hercules-20v-battery-adapter","title":"Black and Decker 20V to Hercules 20V Battery Adapter","description":"\u003cp\u003eUse your Black and Decker 20V batteries on Hercules 20V cordless tools, without buying into a second battery platform. Both run at 20V, so the adapter changes the fitting and not the voltage. Constructed from durable molded ABS with pure copper contacts, for a secure fit and dependable current transfer. This helps you get the most out of your existing battery system while avoiding the cost of another set of batteries and chargers. It also carries battery protection electronics (BMS) inside.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSKU\u003c\/b\u003e PTA-BLA20-HER20\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFits this battery\u003c\/b\u003e Black and Decker 20V (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery voltage\u003c\/b\u003e 20V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRuns these tools\u003c\/b\u003e Hercules 20V (Lithium-Ion) from Harbor Freight\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTool voltage\u003c\/b\u003e 20V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHousing\u003c\/b\u003e ABS (Injected)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTerminals\u003c\/b\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCurrent rating\u003c\/b\u003e 40A continuous (80A peak at 18VDC for up to 2 seconds)720 Watt continuous at 18V nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInternal wiring\u003c\/b\u003e 5 mm²\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight\u003c\/b\u003e 125 g (4.4 oz \/ 0.28 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eColour\u003c\/b\u003e Red, Yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating humidity\u003c\/b\u003e 5–95% RH\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating temperature\u003c\/b\u003e -10 °C to 50 °C (14 °F to 122 °F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUSB port\u003c\/b\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBuilt-in BMS protection\u003c\/b\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat's in the box\u003c\/b\u003e Battery adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWarranty\u003c\/b\u003e 12 months after the date of delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRevision\u003c\/b\u003e Revision 01 (released on March 9, 2025)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose this adapter\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eYour Black and Decker 20V battery and Hercules 20V tools run at the same voltage, so the adapter changes the fitting rather than converting anything.\u003c\/li\u003e\n\u003cli\u003eA Battery Management System inside the adapter cuts power before the battery is drained too far — protection your battery may not have on its own.\u003c\/li\u003e\n\u003cli\u003eInjection-moulded ABS, not 3D printed — no layer lines to split under load.\u003c\/li\u003e\n\u003cli\u003eSolid copper terminals, so less of the current is lost as heat.\u003c\/li\u003e\n\u003cli\u003e5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.\u003c\/li\u003e\n\u003cli\u003eCovered by a 12-month warranty from the day it arrives.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBlack and Decker 20V and Hercules 20V compatibility\u003c\/h2\u003e\n\u003cp\u003eIt works in one direction only: Black and Decker batteries powering Hercules tools.
