Adding an extra 18650 battery to Convoy C8

As a thought as your DIYing some of the host then I have 1 idea but it may cause some clutter. Use a generic driver for a normal LED and then branch the outputs through 4 small switches around the base of the head, one for each colour of the LED.

 

[Moss]

Right, so branch the pos. lead four ways (RGBW), each with a switch positioned between the driver and LED circuit board?

 

[Thom2022]

In essence yes. And then they would all share a common earth. I have no idea how well this would work but from an electrical engineering standpoint I see no reason for it not to work although lumen output may decrease as more segments of the LED are turned on in unison.

hmm. i will have a go with this, think it would need to be 1 switch 4channels.

Did you have a picture of that parallel battery cartridge?

I do I'm just trying to figure out why I can't post up images on here. Is it disabled in the mobile app as that's all I use.

To upload directly you have to be a cpf supporter ($5/mo). But you can use postimage.org, flickr, photobucket, etc to host the image so you can embed it with a link.

And I now see by color you meant different leds, so my previous note about bins doesn't really apply.

You're trying to build a Coast TX10 on steroids. [emoji1]

 

[Moss]

Yes exactly!

As Thom2022 suggested earlier for me, the Coast TX10 has 4 switches.

 

[Thom2022]

Ah that explains it. Looks like I need to sign up to one of those. I will get a picture uploaded for you tomorrow Moss.

 

[Moss]

cool thanks. I also need to work out the picture thing.

I was looking at using the RGBW xml for a project and went to you tube looking for something, don't remember what, and found a video of a guy that maybe used a driver he built, I'm not sure. Anyway, he had it dancing and making all kinds of colors, it was pretty cool. So to answer that question yes it's possible.
To throw in a little more input. I've not seen a higher voltage RGBW LED. I've also not seen a buck driver with four outputs, like the one for this LED. Doesn't mean these things don't exist though.

Was it this?: https://www.youtube.com/watch?v=RRlVgFENvU4

The effect at 0:45sec is exactly what I am trying to achieve..

 

[light-modder]

No that's not it, but same effect.
