Charge controller

Okay, little one. A charge controller is like a very useful and smart babysitter for your toys that need to be charged. When you plug in a toy to be charged, sometimes it can get too much energy which can be like eating too much candy. The charge controller helps to make sure that your toy only gets the right amount of energy, just like your mom or dad helps make sure you only eat healthy snacks. It also helps keep your toy from getting too hot or cold, just like how you like to stay nice and comfortable. That way, your toy stays healthy and strong so you can keep playing with it for a long time.
