This is a battery adapter to fit a 20v DeWalt 20-Volt MAX or a Hercules 20V XP Lithium Ion battery pack.  The adapter was designed, 3D printed, and assembled in the USA.

NEW:  This adapter can now also fit Hercules 20V Lithium Ion XP battery pack.

Battery is NOT included.  You may purchase it from your local Lowe's store.

This battery adapter fits the following batteries:

  • DEWALT 20-Volt MAX XR Lithium-ion Premium Battery Pack 5.0Ah
  • DEWALT 20-Volt MAX XR Lithium-Ion Premium Battery Pack 4.0Ah
  • DEWALT 20-Volt MAX Lithium-Ion Premium Battery Pack 3.0Ah
  • Harbor Freight's Hercules 20V XP Lithium-Ion battery pack

Cautions:

  • Do not use this adapter to charge your battery 
  • Do not short circuit battery or draw more than 20amps continuous
  • Disconnect the battery before it reaches 15volts, (prolongs battery life)
  • Do not leave battery charged at 100% for long periods of time, recommended to store battery at 70% charge (prolongs battery life)
  • Do not leave battery outdoors (especially in hot climates)

    This is a high quality 3D printed part. don't hesitate to purchase this for any project you might have in mind. 10 gauge wire and heavy battery contact connection. Couldn't be happier with this.

    Valuable product, just add alligator clamps, to jump start and 12 Volt vehicle.

    Posted by Kevin on Jan 13th 2022

    I carry a 4-6 AH or bigger battery with me all the time anyway. Just add alligator clips and jump start a dead or cold battery. DeWalt batteries are 20 V so will certainly start a 12 volt vehicle!!!!

    Works exactly as I had hoped.

    I expect I will buy more for other projects. Initially purchased to supplement Dyson's vacuum cleaner battery. I also am using it to power a DEWESoft data acquisition system instead of a 120vac to 20vdc power supply.

    DeWalt battery adapter

    Posted by Russell on May 25th 2020

    This works great! I've been wanting to tap into these batteries for a while and considered making my own adapter, but I found these for $15 a piece and couldn't pass them up. They are well built, lock on the battery easily and pop off quick too. I will be getting a few more in the future.
