How To Get 12 Volt Power From your 20 Volt Tools

- Here is the situation, I have a boat with a 12 volt power system, and no easy way to charge it. What I do have is a ton of ready to use 20 volt power tool batteries for my cordless DeWalt tools. There HAS to be a way to use my 20 volt tools to power my 12 volt sailboat electrical system. At least I think there is. With a few parts and some trial-and-error we figure out how to make this work in today's video.
And a link just for Higgypig!

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.
I totally need to read comments before I make one.
The battery has a BMS on it that will protect the battery from to high/low voltages !
DeWalt 20v max builds them into the tool, not the battery. You can kill a DeWalt battery using the 20v adapter for a old 18v tool or doing something like this.
Low voltage cut off should be 16v, I would dial the output up to 14.5v
Lead acid system will work at that voltage and you’ll get more life out of your step down.
Thanks for the pointers!
Your stepdown device is too small, it will burn if you connect a power hungry load😅
The brand new adapter with a fuze that you admitted shorting out didn’t work? Hummm
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".
I got tired of the droll BS before I made it to the content. Try getting to the point.
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?
We are running 3-4 LED navigation lights, and occasionally charging a phone.
Will need to do the math but so far so good.
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!
What power cut off are you using? I can’t make it out from the video?
TOO MUCH RAMBLING AROUND AND WASTED FOOTAGE = WASTAGE OF MY TIME --> USELESS.
5cells. 3.6v to 4.2v each
Well done
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.
Which low voltage meter are you using? 12v?
Thank God for the "don't recommend channel" option
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.
I do have a 3D printer…. Might just have to steal your idea!
Why not just get a 12v lithium battery? Maybe not cheap but small and powerful…
Partially I kind of wanted to see if this would work. Like the idea of just grabbing a DeWalt battery on my way to the marina and snapping it in. If it doesn’t will probably just get a small UTV Lithium battery.
Links for all three components?
All red wiring? That's a fail. Drink a pickle beer!
Pickles are color-blind.
Have you considered attaching that keel to your truck bumper and dragging it down the road a few miles to rub the paint off?
Probably try that next.
It’s not a failure, just a success that hasn’t happened yet! Therefore no pickle beer needed!
We should all practice this kind of thinking.
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?
Even put a fresh blade fuse in, I think the switch was bad. I was reading power going into the switch but but not out
@@ZeroToAwesome then your all over it
What step down did you use? id like to see if I can make my own.
Just added the link to the one I used in the description incase this link doesn’t work. www.amazon.com/Converter-20V-60V-Voltage-Waterproof-Transformer/dp/B09P2N1X6T
Good luck!
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?
That is a bit of a concern… it is basically running lights and I already swapped those all out to LED. This is definitely more on the experimental side.
@@ZeroToAwesome Since you'll be running it on a boat, there is an opportunity for some efficient water cooling for all those wires when the amperage gets too high. Would be perfect for cold and windy days on the water. Always look for positives when in doubt.
This is just a shill for Big Pickle.
👌
Pickle Surprise!
A salty surprise indeed.
THE PICKLE IS REAL
If you are a good boy all year long he will bring you presents in December.
I bought the exact same battery adapter as yours and mine didn't work either. hmm
Glad I’m not the only one, went with the fuse-less adapter and had no problem!
how much time do we have to waste trying to learn something?
A while
