Review on 🔊 Enhance Your Mobile Audio Power with 500Amp Continuous Battery Relay Isolator: Uninterrupted Performance by Fritz Marrero

NOT able to stay energized all the time. By not conducting load current, only the relay coil gets energized, they go HOT, HOT, HOT. So hot you can't touch it. I ran these relays off a regular 12 volt battery to keep them from over-saturating. I was just checking that they could run continuously and they were NOT. The coil current is 1.5 amps, which is really quite a lot. As a counter-argument, I've bought another brand of 500A relays, which draw much less current (0.5 amps) and never feel more than warm to the touch under the same conditions.
