I'm building a couple LED headlights for my eBike. The bike runs off a 24v LiFePo battery, so I figured, why use a separate battery pack for lights? A 500w motor is hardly going to notice the extra drain from a couple 5w leds.
The problem I've run into is finding an appropriate voltage regulator. I originally bought one that was supposed to accept input voltage of 14 - 30v DC and output 12v DC. Turns out they changed the specs on the thing and didn't update the website till later; now it only accepts 14-16v input. So I returned it, and haven't been able to find a regulator to do the job.
System Specs:
Battery: 24v 20ah - actual voltage 24.5 - 27.5v DC (Cyclone eBike kit)
Lights: two 5W 12v MR16 LED (p/n EO-EL16-51W3-1 from theledlight.com)
I'm looking for a regulator that will output 12v DC @ 1a (or two regulators @ .5a). Or if that's just impossible, I could get a 24v regulator and run the two lights in series. That wouldn't allow them to be switched individually, but I suppose I could live with that.
