will this work?

[pagani123]

so i want to make sure before i buy if this works or doesnt. i want to use rgb led on my dji phantom but im not sure if it will work. the module that adapts batteries of the phantom to (non rgb) led puts out inconsistent voltages (which i was told is normal lipos put out inconsistent voltages). the battery says it puts out 15.2 V 4480mAh (68Wh) and the input for the led controller is 12 volts anyone know if i will over power the controller or any inconsistent voltages will mean the controller wont work at all. if anyone can help it would be great

thanks

It would help to know what LED driver you are using, technical specs would be ideal.

 

You can try a low drop out regulator on the power input and set it for about 11.5 volts. The RGB LED system should still work normally at that voltage but when the regulator looses its ability to regulate, it will be within the tolerance of the LED driver.

http://www.hitlights.com/luma10tm-series-multi color-led-light-strip-starter-kits-smd-5050 heres the led and controller again the led controller needs 12 v and the battery provides 15 but since its a lipo it does not have consistent power

I couldn't find any datasheet on the LED driver you listed which concerns me because it means it was never intended to be used without it's power brick.

 

I couldn't find any pre-built regulators that I would trust myself. If you aren't afraid to do a bit of soldering, you can try making your own. I found a regulator IC that you can wire up that should easily regulate your voltage to the 12V. I still don't know what the maximum input for your device is but I would assume that it has at least a 0.5V tolerance (most things do). If you get at least 4 of these regulators and connect them in parallel then they should be able to handle your device. They have a drop out voltage of 1V at 1A of load and a dropout of 1.1V at 2A of load. They can go up to 3A but you never want to push these that close to their limit. The more you put in parallel the better off you will be, but you shouldn't have more than 8.

 

Do a quick check with a volt meter to verify that they are in fact 12V, there are several regulators in this family and they all regulate at different voltages. Just use one of the batteries as the input, they have an input voltage of 18V so it should be able to handle the 15V battery easily.

i can solder but im not great with designing pcb not sure exactly how this would work like where i would need to wire it up to and everything also not sure if this would matter but here is the thing i am using atm to drive single colored leds

Single LEDs draw very little current, the link you posted is saying up to 6A of current draw. You don't need make a PCB for this circuit, you can solder it up in a bug style arraignment like in the image. You just need to find some way to hold it down so that there are no shorts, I usually try to make leads as short as possible.
