How to power lights with power tool batteries

- In this video, I cover how to use cordless power tool batteries to power lights and a transformer which is not always needed. Using a transformer to transform 18 V power into 12 V power is only needed if the light your using isn't rated for the voltage of your battery. Remember to always fuse your lines for fire safety as well as to never over power the wattage or voltage rating of any device or it may ruin it..😃

I wired mine up straight and absolutely no issues whatsoever. It's on my m18 battery and I have a 12v led floodlight pod. I wired it straight up with a switch and it hasn't burned anything. I love it. It's made super cheap with stiff I already had. I used an old 1/4" impact that didnt work and cut it and mounted the light to it. It looks factory and is way brighter than any hand held light they sell. I love it
Some lights will handle a higher range of voltage. When the volts get to high it will destroy the electronics. Glad it's working for you. What brand and what's the highest voltage you can put on it?
@@offgridutah1 it's a cheap one off of ebay. It says anywhere from 12v-24v
Most led light run either 12 or 24 v. How the battery life?
@@premonjares great, with a 5.0 battery I can use the light for about 4- 4 1/2 hours nonstop
@@codyswilley thats not bad at all given the size it is very portable. I might give it a go
Very nice
if I am trying to run multiple switches for things would I put the voltage step down before the set of switches?
Great simple video. To add a running taillights (no blinkers ) would you just add the 2 additional wires from the taillight in series with the led (headlight) ?
Parallel or the lights will not be their brightest. Series would make them all dependent on one another.
The one you are using is 24volt to 12volt does it matter if u use the 18volt battery
So do you have a link for that step down converter?

I have a Samsung refrigerator Ceiling Light DA97-08428B
I would like to connect to a scooter battery or like this I don't know how to figure this out. Where so I start?
Put a volt meter in the plug you took the light from to get the supply voltage then find a transformer to convert from the voltage that is normally supplied to the partnumber/assembly to the battery you plan to hook up.
If I use milwaukee 12v then I don't need the transformer?
Correct
I want to add a plug outlet to my fishing cart for lights or chargers could I use these method for that
Yes just make sure to fuse it to protect the max power output of the transformer
@@offgridutah1 thank you for the fast response do you have or ever made a video running a a/c off a battery lol here in Arizona we love the outdoors but summer time kills the kids and was thinking about trying to run a small unit of a battery or something like that we have a generator but they make to much noise
@AZ FIRE BREAKS I installed this victron system its strong enough to run an air conditioner.

I have received the A121203 AC/DC buck converter from Amazon that's rated for 10-28V AC input range while output is rated at 12V DC. When I tested with a small engine that produces AC voltage 10-19V with multimeter the output reads steady 12.3 to 12.4V DC for AC input voltages under 15V. When I set the engine to full throttle the input AC reaches 18-19V while the Buck converter output drops to around 2 to 3V DC. I’m staying well within the operating range of the device, is this normal behavior for the A121203 buck converter under no load condition as a form of overvoltage protection?
If the converter is changing ac to dc usually there is a wattage limit that can burn it out if exceeded unless there is a safety built into it. I haven't used that exact one so I can't say for sure.

I had to go back and reread the Amazon listing and discovered notes that depict the operation of the A121203 unit:
1. When the input voltage is AC10-14V, the output current is less than 1A; when the output voltage is 12V, it is not recommended to output with load at this time, because the conversion efficiency is low at this time; the output 12V after loading will cause the output to be unstable and big output fluctuation. The load is too big to start!
2. When the input voltage is AC15-AC28V, the conversion efficiency of the module is ≥90%, and the output voltage can maintain DC12V±0.25V. At this time, the 3A module can support long-term work within 2A, and the 5A module can support long-term work within 3.5A!
Based on these Notes, the unit should not go into overvoltage protection mode at when it sees 16-19 V as that's the range you are supposed to start applying load to the unit.
Do you have a link for that light by chance?

On the Nilight listing it says the light can handle up to 30v
That may be the case for the listing they have. When I bought mine it didnt have the rating that high. This video is to teach people how to transform voltage. Don't hook up the transformer if it isn't needed. If the range of yours is 12 to 24 by all means bypass it. I looked at the current listing for this light and the documentation for this one now currently advertises up to 30v.
the rigid LEDs are 9 to 36v , so no need to have a transformer
I hooked mine up like this and it worked for a little and now turns on but immediately off again it won’t stay on constantly
How full is the battery it needs to be full when it gets low it will turn off. Also could have protection built in if one of the strands in the wire is touching something it shouldnt.
How long can the light run for ?
I haven't done a full test but it should be a few hours min.
