Headlights for a new controller system

[A_LiteralPileOfDogs]

I currently ride a Radrunner with most of the proprietary plug-ins, but I recently got an upgraded motor kit that includes a new controller with the more "traditional" electronic wires which means the "plug and play" parts I currently use won't be able to be plugged in.

While I could cut the connectors off and just solder the new wires together I'm not knowledgeable enough to know if the current voltage and wattage will be safe for any of my current parts.

The specs for my new system areas follows:

48V / 52V 1000W rear beach snow fat hub motor wheel

48V / 52V 18 mosfet sine wave motor controller

LCD-SW900

52V 21Ah battery

I reached out to Leafbike (The maker of my new motor kit) to ask which wire exactly is for headlights. I'm hoping someone else here might have experience with these type of systems and can help me figure out how to connect a new headlight to the controller I included here.

Thanks y'all

Very few controllers support lights. The ones that do, don't provide enough power to run lights, but only enough to power a relay that can turn on a circuit to power the lights. The Leaf controller definitely doesn't support lights.

The first thing you need to do is determine the voltage requirements of your accessories. If the old controller is still hooked up, you can use a voltmeter to measure the voltage going to your lights, etc. Once you find that out, you can add a buck converter to convert the voltage of your battery (48V), to the voltage your accessories use. That may be 6V or 12V, or something else. If you can list the accessories, someone may be able to help determine the power level required as well.

If it's 12V, then you could add something like this with the inputs tapped into your battery output leads. You could get splitters to do this, if you don't have soldering skills, etc.

This one is sized for 10A at 12V output, so 120W, which is usually enough to power several light, and maybe a usb charge port, etc.

I never thought to run the lights power directly from the battery's terminal, but that sounds like a safer bet than wiring it into the controller. From what I've seen in another forum about changing the headlights in radrunners the voltage from their lights do seem to be set at 6v.

48V to 6V buck converters are less common than 12V, but you can get one with a variable output voltage and dial it in to 6V:

The other route would be to get a 48V to 12V, and a 12V to 6V. The 12V is handy if you want to add a 12V receptacle to power other accessories or chargers.
