## Description

Adapter for DeWALT or Hercules 12v Max battery 12 gauge dock power connector - desertcart.com

Review: Very Well Built 12 Volt Battery Adapter - This fits very well on the 12 Volt batteries. I plan to power some things remotely using the 12 volt batteries, and then being able to slip this on and off with a new battery is perfect. I had adapters for the 18 volt batteries but wanted one for the 12 volt ones to try some other things out. Be sure to fuse the output for whatever circuit you are setting up. I wish it came with an inline fuse, like most of the 18 volt ones. Maybe there is not as much of a demand for the 12 volt adapters, but it seems like more and more uses will come into play for the 12 volt batteries.
Review: Fish finder powered by 12v dewalt battery setup - Excellent purchase, wired my 12v fish finder with this adapters, powered with 12v 7ah knockoff dewalt power tool batteries. These things simplified my kayak fishing setup, saved my money on more expensive lead acid battery types that I had a tendency not to charge before going fishing.
