Rekcharge Large Battery Box with Tie Down Strap

Yes, you can put a lithium battery in a standard 12V battery box, provided the physical dimensions of the battery match the internal space of the box. Most lithium units are sized to match the group 24 or 27 footprints of traditional batteries, making them a straightforward fit for most standard portable housings.

Using a box is a smart way to protect your investment from knocks and dust, especially when you are moving the battery between your vehicle and the campsite. Because lithium batteries are significantly lighter than lead acid units, a standard plastic box is more than strong enough to handle the weight.

Venting is a critical safety feature for a battery box, especially if you are using traditional flooded or AGM batteries. While these batteries are typically sealed, they can release small amounts of gas if they are overcharged or if the charging system develops a fault. Proper venting allows these gases to escape, preventing a dangerous buildup in an enclosed space.

Even if you are using a lithium battery that does not gas, a vented box helps manage internal heat buildup during heavy use. For most setups, a standard box with integrated vents or a lid that allows for natural air movement is enough to keep your system safe.

Explore our AGM Deep Cycle Batteries to see which units require more airflow, or find a smart regulator in our DCDC Chargers collection to prevent overcharging.

Standard plastic battery boxes are generally weather resistant rather than fully waterproof. They are designed to protect your battery from rain, splashes, and road spray, but they are not built to be submerged or to handle persistent heavy pressure from a hose.

Most boxes feature a lid that overlaps the base to shed water, which is perfect for use in a ute tray or a caravan A-frame. To maintain the protection, ensure any external connections like Anderson plugs have proper dust covers or are positioned in a way that prevents water from pooling inside the terminals.

Check out our selection of Anderson Plugs with protective covers, or see our Solar Cables & Leads for watertight entry options.

The best way to secure a battery box is by using a dedicated mounting tray or heavy duty cam buckle straps. A loose battery bouncing around in a ute tray can lead to damaged terminals, short circuits, or a complete failure of your power system on rough corrugated tracks.

Most boxes come with integrated strap points that allow you to lock them down to your vehicle floor or a drawer system. For a more permanent and secure fit, bolting a metal tray directly to the canopy floor and strapping the box into it provides the best stability. This keeps the weight low and fixed, ensuring your connections stay solid even when navigating washouts and rocky creek crossings.
