Simple Basic LED Circuit (How to Use LEDs)
Nov 07, · The cathode goes into the ground—it can be soldered directly to the negative port of the 12v battery. The anode should be wired into the on/off switch, which is then wired into the positive port of the battery. At this point, it is a good idea to check that the home lighting system works. Oct 20, · how to connect led strip to 12v battery | How to Repair Remote Strip LED Light 12volt batterycharge?HiI am Raj Welcome to our youtube channel Technical jugaa.
My situation is this, theres this old farm building i want to do up and make into a chill out room, but the place is not connect the any type of power supply, or if it was im not gonna try and fix it. If i bought a simple 12v led strip and a 12v battery box the ones that support AA how long would that last for?
Thanks for any help or suggests and reading :! Answer 7 years ago. Its really that simple ;- Sound? Try and find some PC speakers with an external power supply. I know I have some that have a 12V power brick -replace with the battery! Answer 6 years ago. So the way to find you answer. First you need to know a few numbers. First what is the total amperage draw of all of your LED's combined. Next you need to know the milliamp-hour mah rating of your battery pack and do a little math by dividing your supply by your demand.
Those are the real pieces of the puzzle missing from your question. For example using some made up numbers if your batteries combined give you 12v rated at mah 1. Now to the question about the solar panel. The peak wattage of that panel is 1. Another suggestion would be a battery meant for RC vehicles.
Everything I have purchased for my RC projects has come from there. They are in the U. Follow up answer. I missed the question about control. That would be a matter of how much control or what type of control you want. If you just need on and off just a simple toggle switch in line with the negative wire will do. If you want other types of control, flashing, fading, on when it gets dark, etc.

Step 1: Get Some LEDs
For example using some made up numbers if your batteries combined give you 12v rated at mah ( amp hour) and your LED's draw milliamps ( amps) your battery pack will last one hour (mah/ma = 1hour). Using the same figures if your LED's draw milliamps your battery pack will last 2 hours (mah/ma = 2hours). So, a 12V battery wired to four 3V LEDs in series would distribute 3V to each of the LEDs. But that same 12V battery wired to four 3V LEDs in parallel would deliver the full 12V to each LED - enough to burn out the LEDs for sure! Wiring LEDs in parallel allows many LEDs to share just one low voltage power supply. Jul 26, · However, your "12V" battery may be somewhere around (say) to volts when fully charged, and as there was no mention of a charge controller, it might even be higher (depending on battery size, type, and other factors we know nothing about). I would have taken 15 volts as a source voltage, taken the OPs word.
LED lights are a popular way of saving money in the home. They last for many hours, and a gently used light can last up to 25 years. Most LED lights are arranged so that they can run off of a 12v battery—in fact, 12v lights can cause a short when plugged directly into a socket, which usually have v current. This can be very dangerous, and so the best solution is to run these lights through a relay instead. Check out some battery-powered LEDs intended for use in a car.
The first thing that needs to be done when connecting LEDs to a battery is to consider where they will go. Batteries operating lights on a high wall, for example, will need to have something supporting their weight. Unless you are installing these near an existing 12v battery supply, prepare to build a ledge, box, or other support. Leaving a battery to dangle will eventually cause connections to break.
This is the length of wire necessary to connect the LEDs to the power supply. Batteries and switches should be checked for faults before being wired to the LED home lighting system. This can be done by checking the current with a voltmeter, or by wiring both items to a lamp or device which is known to work. Once the LEDs are in position, examine them and find the leads; the negative lead or cathode , can be identified in one, or more than one, of these ways: it is the shorter lead, it is a flattened section on a round LED, or inside the LED, each lead is attached to a triangle-shaped node; the positive lead or anode is attached to a larger node.
A diode test function meter will light up the LED when correctly applied. When it is lit, the black test lead will be attached to the cathode, and the red test lead will be attached to the anode. When you are sure which lead goes to which, it is time to solder the wires to the 12v battery.
The cathode goes into the ground—it can be soldered directly to the negative port of the 12v battery. At this point, it is a good idea to check that the home lighting system works. Problems may include a blown fuse or damaged LED easily done during wiring , or a loose connection somewhere between the lights and the battery. Correcting these problems is a simple task, and if the home lighting system is wired correctly, there should be no problems in using it for the foreseeable future.
