Review on 🔋 Stinger SGP38 80-AMP Battery Isolator and Relay - Enhanced Power Management for Vehicles in Sleek Black Design by Dee Rawls

This contactor has very few specifications. The contactor is designed for a continuous current of 80A. However, there is no information on the power factor requirements (if any) for the loads. It's actually just a high power SPST relay, not a true battery isolator. It does not monitor battery voltage and will turn off loads before the battery level drops below a level that could endanger it. By the way, here is a combiner/isolator that actually prevents battery damage from deep discharge: https://www.amazon.com/Victron-Intelligent-Battery-Combiner-Cyrix-ct/dp/B0738JGVZ9. Part of the missing information is the steady state current draw at the coil. This is the number I can measure on my desktop PSU. When the contactor is at room temperature and activated with a standard automotive voltage of 13.5 VDC, it draws about 500 mA - about 6-1/2 W. That seems high, so I decided to see if the coil current itself would heat up the relay. And so it was. 100 degrees Fahrenheit! In the second photo, the relay case heats up to 168 degrees Fahrenheit (75.6 degrees Celsius). Remember that no current flows through the main contacts, which could add even more heat. This unit has been rated fairly well here at Revain and should perform well in intermittent use, e.g. B. when switching a small starter. Rather not as a load-shedding relay with a long duty cycle. He returns to Revane. Three stars for the complete lack of technical characteristics.
