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?
