Hello, I’m trying to make a simple wireless igniter using the below wireless relay. I would like to add that this is solely for personal use to ignite nichrome wrapped igniters for testing motors. I intend to use a 1000mAh 20C-30C 3s Lipo. I also plan to open up the transmitter and put it in its own box with a power switch for a little added security. At the “pad” (there will never be a pad, just test stand), I’d like the receiving unit to have a voltage meter, power switch and continuity indicator if possible for everything from ematches (low current) to larger wrapped igniters. There are two main questions I’d like to get advice on: 1. Should I add an inline resistor between the battery and the relay? It says it’s rated to 40A and I believe the battery could throw 20-30A. Is it necessary? 2. Is there a safe and easy way to add a continuity check at the receiver? Could I put a multi position switch that can be switched to send current through an indicator LED and resistor with inline momentary switch for continuity and then toggle that switch to an ARM setting to put power to the relay? I’d also like to put another switch downstream from the relay with an LED between the relay and switch to indicate if power is flowing from relay before closing the downstream circuit to the igniter. Open to any and all suggestion from you more talented EEs. Beware, I may come at you with MS Paint drawings. Parts: 12v 40A wireless relay. https://www.amazon.com/dp/B075QJ8QWM/ref=cm_sw_r_cp_api_i_qJKRCbGQX26AS Thank you much.
