    Welcome to the Forums.

    We need more information. What kind of battery are you using? Is it fully charged? What LED settings are you using? Pictures of setup?

    Battery is 7.4 li-ion, fully charged. Settings are default. I dont have anything but momentary switches, battery, speaker, and main led hooked up for testing.

    But what is the LED setting. If you have it wired in parallel, you might have the setting set too low.

    If you have them wired in parallel, that's only 350 ma per led (very low). Ideally, you'd wired them in series when using the 7.4v battery and leave the setting at 700 (if using a tri-rebel). If you wanted to leave them in parallel, you'd have to basically double the output to about 1400, though, it's likely that the two LEDs will not use exactly the same current, so tread carefully if going that route.

    Cvsickle is right, you would need to raise the value to 1400.

    Cvsickle is right, you would need to raise the value to 1400 for a parallel setup. You can wire it either way and it'll be fine.

    Still not working. I originally had my setup with a pc 2.0 and everything was working fine.
