The Engel Series 2 Smart Battery Box is the world’s most advanced 12V battery box. It’s a powerful 12V battery charger, a portable power source, a dual-battery system and a battery management system all rolled into one.
The handy LCD screen makes it easy to see how much battery you have left. This battery box has a 300-watt inverter, so you’ll be able to charge more than one device at a time. It’s compatible with LiFePO4, Gel, Calcium, AGM, and lead-acid batteries.
You can charge the battery in your Engel Smart Battery Box by 240V mains power with the included adapter, or when you’re away from the grid from your vehicle’s DC cigarette socket. You can also charge via your solar panel or via the Anderson socket.
