Review on ⚡️ Erayco 100 Amp Circuit Breaker: Manual Reset for Car Marine Trolling Motors, Boat & ATV Power Protection, Waterproof & Ideal for Audio Systems, 12V-48VDC by Flavio Iyer

Bought the 200A version of the circuit breaker on May 19, 2021. Installed it as the main switch for my 300Ah LiFePo4 battery pack. Tested with loads up to 150A at home. It failed on its first field use on July 9, 2021. It cut out after a few minutes at 120A (water heater). After cooling down, it continued to work for a few minutes because it didn't work at all. The block was high-impedance after the 2nd actuation, the reset didn't work and after cooling down it still reported > 1 ohm. Completely ruined my trip.
