Dual Battery Isolator

Voltmeter display

Equipped with LED indicator light and displays the current voltage of the battery with higher voltage.

Dual Battery Isolator

IP68 waterproof

This dual-battery insulator has a waterproof rating of IP68, has strong waterproof and dustproof functions, and can work normally in harsh environments such as humidity.

Dual Battery Isolator

Protection against high/low pressure

When the input voltage exceeds 17 V or falls below 11 V, the circuit automatically disconnects. Can better protect the battery and extend the battery life.

Product Functions:

  • The shell is made of fiberglass reinforced nylon, which is strong and durable.
  • It has a built-in LED display that lights up when vsr is involved.
  • A unique memory mode enables zero power consumption when the engine is turned off.
  • When the input voltage is lower than 11V or higher than 17V, the current circuit is automatically disconnected.
  • This dual battery isolator automatically isolates two batteries when not charging and automatically merges the two batteries when charging, with no voltage drop compared to battery isolation diodes (0.6 V), compliant with ISO884. Suitable for installation in RVs, off-road vehicles, recreational vehicles, ships and machine rooms.

I tried this out on my bench first and the trigger voltages are as expected. I was worried that it'd have a high parasitic draw with the voltage display, but the display only turns on for a moment when you press the button. The draw otherwise was too low to register on my bench power supply.I'm using this to keep an auxiliary battery on my truck charged. I've got a crane winch on the back that I don't want running from the ignition batteries, so it gets its own battery that ties in to the trailer charging line with this isolator.
