I am wanting to use 2 16.4ft rolls of multicolor LED strips in my enclosed trailer for lighting. They come with 110v power supply that plugs into another coverter that the LED lights plug into. Is there a way I can bypass this power supply? I’m intending on using either 2 6v deep cycle batteries or 1 12v and use a voltage regulator for a constant 12v.

Here’s a link to the kit purchased


  • \$\begingroup\$ If you have a 12V battery, you already have what you need right? Just a note though, you can't feed 12V into a linear regulator to get 12V out. You'd need a buck-boost if the LED strip really needs a stable, unchanging 12V \$\endgroup\$ – Orotavia Mar 14 at 18:51
  • \$\begingroup\$ @Orotavia. Not exactly, I figured it wasn’t as easy as clipping the input wires to what the power supply plugs into (white box) Is it truly that easy? \$\endgroup\$ – 50_Chev Mar 14 at 18:56
  • \$\begingroup\$ You'll still need the white box, it probably has 3 MOSFETs in it to control the current on the 3 colors in the LED strip. Or replace it and the remote with your own color control circuitry. \$\endgroup\$ – CrossRoads Mar 14 at 19:02
  • \$\begingroup\$ You might be able to get away with 14.2V or drop the voltage with an extruded aluminium heatsink also useful for blocking glare with indirect light. or add a few power diodes to drop 2.1V otherwise you need a 5A ultralow LDO regulator with 0.5V min drop \$\endgroup\$ – Sunnyskyguy EE75 Mar 14 at 19:04
  • \$\begingroup\$ @CrossRoads I would like to retain the color control that came with it. Since it has a remote and all the jazz built into it. I’m assuming that’s what that white box is. I do apologize for being so electrically ignorant (haha) \$\endgroup\$ – 50_Chev Mar 14 at 19:10
