ELI5: Explain Like I'm 5

Battery isolator

Okay kiddo, imagine you have three toys: a car, a truck, and a boat. You have a big box with three compartments in it, and each compartment has a switch to turn the power on and off.

Now, let's say you have some batteries: one for the car, one for the truck, and one for the boat. You want to be able to power each toy without the batteries running out too quickly, and you don't want to accidentally drain one battery while you're playing with another toy.

This is where a battery isolator comes in! It's like a special box with switches that helps keep each battery separate and safe.

When you turn on the switch for the car compartment, only the car battery gets power. Same for the truck and boat compartments. This way, you can play with each toy and the batteries will stay charged without any extra effort from you.

So, a battery isolator is a helpful way to keep different batteries separate and make sure they stay charged!
