An LED indicator can give you a useful visual on the status of your battery. This will enable you to find out when the battery needs a charge without getting it out and testing it yourself. If you’re confident that your battery is going to be able to hold the charge you need then getting a plain battery box without this feature wouldn’t be a problem.

Having easy access to the terminals can be a useful feature for battery boxes. Even though the box is there to protect them from the elements, you don’t want to have to work too hard when it comes to using the battery.

Easily Portable

The easiest way to do this is by choosing a box with a big handle so you can simply pack it away and take it out when you need it.
