Ultimate’s portable Battery Box is suitable as permanent protection for your battery. Among other things, this battery box protects the battery from penetrating moisture, dust and dirt. This ensures that the chance of failure due to dirt or corrosion is very small and the life of the battery is significantly extended. You do not need to open the battery box once the cables are connected. Thus, the battery is completely sealed and therefore resistant to all weather conditions. The battery box features two 12V lighter plugs and two USB ports so you can connect a cooler, phone or navigation equipment to the battery box. With the included strap and brackets you can secure and fix the box to the bottom of your boat.
