If im wiring 12 together for a project what voltage battery, and what type of resistor (if any) should i be using?

HI Stew. I used 200ohms to drive 4 RGB leds in parallel with source of 9volts. All four connected to same resistor. I haven't measure current or voltages but they bright pretty good. let me know if you need any measure.

I recommend a 9v battery with a 1k resistor. You could fine-tune the voltage and resistance, but those are easy and quick numbers that I've tested on a string of 10 LEDs.

Hook all 12 in parallel and run it with 3V. It will work great and you won't have to spend a fortune on batteries. Using a 9V battery means you are wasting 2/3 of the battery power heating the resistor. They are not plain LEDs. They contain a controller chip. The rules are different. (But I would never use 9V batteries to run any LED for the same reason--you are wasting most of the energy of the battery!)

I'm planning to use a 9v battery to light up 2 or 3 of these LEDs; I see F. Solano has used a 200ohm resistor to accomplish similar, but Kapowzer claims a 1k resistor? Any advise re: which to use would be appreciated - thank you.

First, are your strings of LEDs labeled to work with 12 volts? If they are both 12 volts rated, connect their wires (+ to +12v and - to GND or 0 volts) in parallel. If they are labeled to work on 6 volts, connect one - wire to GND, the + wire to the - wire of the other string, and then connect the + of the second string to the +12 volt output of your supply. Of course, you must prepare a power cord for your 120 or 220 AC service to connect to the two AC IN screw terminals. Good luck.

A battery is a battery and voltage is voltage. If the machine will run from 12V DC there is no reason you couldn't use it. I would have to imagine there are better solutions for that though.

If you can find a molex connector you could use just the pos (12V) and neg wires to connect to your battery. Here's a link to help you figure out which wire you need. http://i92.photobucket.com/albums/l32/rougeneon97/dew%20Heater%20DIY/molexpinout_zpsdeb42ea2.png

Depends on if you want to run in series or parallel. I would recommend grounding them independent and using your current 12v "positive" wire to power them. Take the "hot" wire from your current light bar and splice the positive wire from these into it. If you're unsure which one is positive touch both leads to your battery they only work one way.

This is a 12 volt light kit. The best thing is to get the 48 volt to 12 volt converter this way you are drawing from all the batteries and will work better.

I made my own. The controller has terminal strip screws for all the inputs and outputs. I have the controller within 5 feet of the battery. Use at least 12 gauge wire for each, the positive and the negative. Larger gauge would be better. I crimped on connectors to fit on the controller screws and my battery has screwed studs that I also crimped connectors on to fit.

Get the voltage and polarity right and you should be ok. Just be careful not to fry it.

Any battery works. But it depends on wattage of pannels some larger pannels are built for 24volt instead of 12volt. Check the specification. It is better to use a deep cycle type. You can have multiple ones, but have an even number of them.

yes you will need a 12volt supply. The terminals are bare wire clamp ons so you shouldn't need any connecters. This is for single color LEDS not RGB version of LEDS.

Kendrick has it spot on. Six - 6v batteries at 225 Ah should work with a 1kw for a 12v battery bank.

I just used a 12v adapter I had lying around. I cut the end off and used a multimeter to make sure the polarity was correct and hooked it to the board. Please, do be careful about the where you put the positive and negative. I remember reading on the net that this device won't protect itself from reverse polarity on the dc voltage. Meaning, the circuit board will be ruined.

Use TWO/2 Gauge wire and you'll be fine... better have your engine running though... 1500 watts will drain the battery very quickly.

The end of the wires are a bare connection. You would use a connector to wire it to a 12V fuse protected circuit.

hello, there is not problem useing 12/2 wire, it is also good useing that size for the futer if you want to use higher watt lights.you should use larger wire if you havea long runs.Brent

This is a 12V battery. If you put 4 of them in series you'd get 48 volts, but that's far from optimal.

U can use either reg battery cables or smaller 12V cables, battery has both large & small post. I've had 1 for 2 yrs its a good battery for trolling, get 4 to 5 hours on 50lb motor
