How To Get 12 Volt Power From your 20 Volt Tools 

I am glad I could fast forward to the parts I wanted to watch.

You said you shorted the battery several times using the adapter with the fuse, so the fuse did its job just have to replace it.

Thanks a bunch for this video. Me and my old boss finagled a way to mount a 1.2gpm sprayer pump onto backpack sprayers, wired up with 12v electric fence batteries (lead acid, so heavy) and a switch to never have to pump by hand spraying ever again and I had a feeling we could run them with our Dewalt batteries and step down converters. Been trying to find the parts and do the math for the last year, just been afraid to pull the trigger and buy a bunch of parts without knowing for sure. If you have any affiliate links on Amazon so you can make a cut of the profits, I’d definitely use your links!

The battery has a BMS on it that will protect the battery from to high/low voltages !

What power cut off are you using? I can’t make it out from the video?

To fit it into your boat, you could have a 3d printer, and print of your own plastic base, that accommodates all those things into one base.

It’s not a failure, just a success that hasn’t happened yet! Therefore no pickle beer needed!

Which low voltage meter are you using? 12v?

Links for all three components?

Well done

How many amps does having all lights and powered things on the boat on at the same time? I suspect your amperage is going to exceed the step down transformer capabilities. Certainly those wires. This is why your 12 battery has 10 gauge wire to connect it to the boat. You need a beefier transformer. More like what is in a 12V wall wart and a step down that can handle the 20 or so amps all your stuff needs. What is your breaker panel rated for?

have you checked how many amps you need to run your boat? and compare it to what the dewalt battery puts out? or even the motorcycle battery?

Have you considered attaching that keel to your truck bumper and dragging it down the road a few miles to rub the paint off?

What step down did you use? id like to see if I can make my own.

Did you check that there was a good fuse in the fuse holder? It’s such a simple adapter not much to it. Switch or fuse?

A 20V tool battery in reality is an 18V battery. 5 Cells times 3.6V per cell = 18V. That's the nominal capacity. A battery with 10 cells has every two of them in parallel, so again it's 5x3.6V = 18V. Fully loaded, the battery has more than 18V, and nearly empty, the battery has less than 18V. That's why 18V batteries and 20V batteries are the same (we are talking about lithium tool batteries), the 20V-thing has to do with advertising, the consumer thinks "20 is more than 18 so it must be better". Some of them even call their 20V systems: "20V max".

If your 20v batt won't light up the charger, you need to take a hot 20v and jump off the "dead" one with some jumpers. +to+ -to- of course.

5cells. 3.6v to 4.2v each

Thank God for the "don't recommend channel" option

how much time do we have to waste trying to learn something?

I bought the exact same battery adapter as yours and mine didn't work either. hmm

THE PICKLE IS REAL

Your stepdown device is too small, it will burn if you connect a power hungry load😅

Pickle Surprise!

All red wiring? That's a fail. Drink a pickle beer!

Why not just get a 12v lithium battery? Maybe not cheap but small and powerful…

This is just a shill for Big Pickle.

I got tired of the droll BS before I made it to the content. Try getting to the point.
