100 W
So I added a tail light and turn signals to my 48v ebike. I'm using a DC to DC converting to power the lights, I read online somewhere that typical automotive electronics run on a higher voltage than the rated 12v, something more like 13v-14v. I have my DC to DC converter set to about 14V, the tails lights and turn signals work great. Now I would like to ditch the battery that came with the headlight* that I'm using (8.4v/4.4 Ah) and run it off of the DC to DC power supply. Will the higher volts destroy the light? I already purchased a 12v-85v LED for my 20s lipo bike. Should a just order another one of these variable voltage lights to avoid any incompatibility issues? I'd like to use the light I already have, if I'd have to end up getting another DC to DC converter I'd probably just get the variable voltage headlight. I'd like to see if I can save the $15 for the variable voltage light and just use the battery powered light I already have at a higher than rated voltage? Anyone have any experience with this?
*SecurityIng Waterproof 1200 Lumens XM-L U2 LED Bicycle Light 4 Modes - from amazon. I strongly recommend against this light, the battery was shorting out at two poorly soldered connections on what appears to be some kind of BMS or overcharge protection board. Also the light is only has 3 modes and it certainly doesn't appear to produce 1200 Lumens.
