I've got a small wiring question, I've decided to go for a removable link and an LED power light, so that should I get the opportunity, the robot will be legal.
I know what I'm doing for the removable link, but I need some advice for the LED. I thought I probably wouldn't be able just wire the LED straight into the 5s battery, but seeing as I had two LEDs i decided to test that hypothesis. brief flash of light, funny smell, theory confirmed. So my question is, how do i power the LED from with the 18.5v current I have? Do I need a resistor? If so what type?
Many thanks.
