Hooking up lights to 12s battery pack

Esk8 Electronics
1

Hello Guys:
I’m looking to power up some lights for my esk8 from the battery pack and turn them only if possible from the Hoyt Puck remote.

The lights would draw 8.4V@0.5A, the Stormcore 60D only provides 5V on the 5v auxiliary port, so drawing currentt from the ESC is no option.

I wated to draw power from my12s battery pack itself which operation voltage runs between 50.4V full charge and 36V cut-off voltage.

I’ve tested a LM2596 buck coverter but it only supports 10S batteries, it burned at 48V

What off-the-shelf electronic component are you using these days?

Polulu has some interesting options, not sure if you looked there or not

I bought a couple of these:

Output voltage is constant, but output current is varible depedinf on the input voltage.

The lights I’m powering are two of these in parallel:

I bought those exact ones for my old headlights too. I have the same ones but from aliexpress. They increased the price a ton on them tho. Pretty good lights though

Would you please send me the link of the ones you bought?

mmm the exact seller seems to not be around anymore but it was similar to this

Next time I’ll go with that.

Do you know of any switch with wireless receiver to turn on/off the lights with the Hoyt Puck remote?

I have not heard of something like that unfortunately

Lezyne eBike Micro Drive 500 Headlight Black, High Volt https://a.co/d/4DJYLHP

I use this on 12s. Quality part. No buck converter tomfoolery.

Only complaint, it’s not a shaped light beam. It will blind on coming traffic if you are inconsiderate and angle it parellel to the horizon.

You could use something simple like this but it would be a seperate remote:

433Mhz Wireless RF Switch, DC 12V 4CH Channel Long Range Wireless Remote Control Switch Relay Receiver Module, Transmitter Toggle Switch RF Relay (2 Transmitter & 1 Receiver) (433Mhz) https://a.co/d/7awSAfv

This is amazing!, just bought two of those thanks! @Arzamenable

Do you know if anybody has been able to shove the electronics off a remote like that into a puck?

This also just wire straight into your battery, though you will have to install a switch separately or use your BMS discharge function as an on/off switch.

What SPDT switch are you guy using to power up high voltage lights?

Most push buttons are rated for only 24V maximum

It’s just a normal spdt 120v ac switch. The lights have very low inrush current and fairly low max current draw. Has not been proven to be an issue thus far

Nah I sell a toggle switch, but that would work just fine too

19

Actually, no… might be interesting to attempt tho. It’s a cheap part and it comes w two remotes. Give it the ol’ College?

Part is already ordered lol

Hoyt said it couldn’t be done but now I’m determined lol
