BMS E- Switch, Step Down convertor & LED Power switch

On my son’s board, the @treenutter Caldera deck with @psychotiller 6 shooters on PT RKP trucks, I wired an LED power switch in a creative way and I wanna make sure it’s not gonna bite me in the ass.

I connected a lead from POS of the battery pack & NEG of the BMS to a 12v 3a Step Down convertor so it will only be powered when the BMS is powered. I connected the POS & NEG from the step down convertor to an LED push button latching switch LED circuit. Lastly I connected the throw of the LED push button latching switch to the BMS E-Switch port. This essentially powers the LED on the switch via the Step Down convertor when the BMS E-Switch circuit is completed.

Is there anything I’m missing or should this be good to go?

What’s missing is pics of bright blinky lights! :see_no_evil:

…and that sounds like a solid electrical setup.

Yes!! Make sure they can take the volts of your pack on the input. Because most use like 36v rated components which is to low. For a 10s pack 42v I’d make sure it can handle at least 50v in the input.

I use one like this… Look at this on eBay http://www.ebay.com/itm/262877030319

Most are rated to 48v, which is well within the limits imposed by a 10s pack.

This is rated to both 48 and 58V :stuck_out_tongue: Anyone found one that is rated for a 12S pack and a good switch to go with it?
