I am doing a DIY DC battery backup and when I tested it with my two power heads there was no issue but when I tried it with my Jebao DCT-6000 the controller flashed blue lights (see video). I am using this as a relay switch (https://a.co/d/30xwisx) and it's rated to 10 amps and don't see anywhere that mentions the pump drawing more than 4 amps. Anyone know what this flashing means?
