  • 【500 AMP BATTERY ISOLATOR】The 500 Amp Battery Isolator is designed to isolate a second battery or applications where multiple batteries need to be isolated, making it ideal for audio, navigation, winches, generators, etc., without dropping the voltage of the second battery as traditional isolators do while preventing the main battery from discharging
  • 【PREMIUM QUALITY】500 Amp Battery Isolator Audio Relay uses high quality copper coiled wire to dramatically increase electrical and thermal resistance while extending service life, meets or exceeds OEM standards, and is endurance-tested for extreme environments
  • 【HIGH CURRENT ISOLATOR】The rated voltage of this battery isolator is 12V, it can provide 500A constant current stably under 12V voltage, and 700A under surge power, which is upgraded on the traditional isolator, and it will not cause voltage drop to other batteries except the main battery
  • 【KEY FEATURES】Prevent the main battery from discharging, when the main and secondary batteries are connected in series, it is easy to affect each other when charging and discharging, when your engine starts the battery isolator can connect the two batteries together and isolate them when the engine is turned off, which reduces the second battery's natural loss to the main battery and prolongs the service life of the main battery
