### ⭐⭐⭐⭐⭐ Smart dual battery isolator with meter
*by G***B on August 20, 2024*

The POWO by Carlife dual battery isolator with digital display is easy to Install and works great. The display is a little hard to see in bright light, but that is the nature of LED technology. The unit is installed in the back of my truck and connects the two batteries that power my winch, which has no connection to the truck's electrical system. The batteries are connected through the isolator to a battery charger powered by either a generator or the trucks 120v outlet in the bed. The system works great for light use, and will hopefully never get tested under heavy. (which would mean I am stuck up to my doors)
