Power Wheels 18V Upgrade Milwaukee Battery (Easy Way!)

This is convenient if you've already got batteries from your power tools so there's not much cost at all for this method. You can also take the top off your Power Wheels battery and get the adapter that way if your ready to fully commit.

Here is the adapter: https://www.amazon.com/gp/product/B01...

The adaptor is not needed if you just want to wire directly into the battery. Just cut off the plug and connect an inline fuse holder (few dollars at ace hardware) and splice your male ends on. I would leave a little extra wire on the plug (and save it) so that you can wire nut it back in if you want to revert back to it in the future.

You can use 30a or 40a fuses. I am currently running 40a in mine.
