Thread: How to power the safety LED?

    Hi Pete

    I use 4s Lipo batteries in all my Feathers and found a 340 Ohm resistor just before the LED on

    the positive side works fine-use a red LED-they are usually rated highest and connect the negative

    to a negative outlet like battery or ESC.

    You will need a resistor, but as 4s is 14.8v you can use a 680 ohm resistor. You can also just use some prewired leds for 12v, they will be fine at £15v - i used them before. - just some i found on ebay. there are plenty of sellers. Also you can use 12v led strips - i have used these on 5s.
