Protect your Battery with the Best Quality Battery Boxes out in the Market! Get them now with our Charging Adapter, Ring Terminal Harness, Battery + Box Combo, Battery Box and Bluetooth Battery Monitor! Battery boxes not only protect the battery but also protect others from risk of shock or exposure to potentially harmful battery acid leaks. Keeping your battery secured in a sealed, protective case isn’t just safe, it also ensures your battery doesn’t make contact with other metal objects which can cause short circuits. Without a protective battery box, high powered batteries can generate high voltages that may cause electrocution. These battery boxes come with outputs that will allow you to charge your smart phones, tablets or anything that uses 12V or USB.
