300Ah LiFePO4 Battery for Caravan and Off-Grid Power
Build a larger energy reserve for your caravan, motorhome or off-grid setup with the Autory AT-12-300 lithium battery. It provides 300Ah capacity and 3840Wh of nominal energy storage in an all-metal enclosure with integrated mounting brackets.
A-grade LiFePO4 cells and a built-in battery management system combine with up to 300A discharge capability for demanding 12V power systems.
Pickup from Brisbane or Melbourne
This battery is available for pickup from our Brisbane or Melbourne warehouse only. Due to its weight and dangerous-goods freight classification, delivery is not offered for this item.
3840Wh Nominal Energy Storage
The AT-12-300 has a nominal voltage of 12.8V and a capacity of 300Ah.
It provides three times the nominal storage of the Autory 100Ah model and 50% more than the 200Ah model. That larger reserve supports setups with greater daily consumption or longer periods between charging opportunities.
Connected loads can include fridges, lighting, pumps, fans and inverter-powered appliances. Actual runtime depends on consumption, charging input and system losses.
Up to 300A Discharge Current
The battery supports a maximum discharge current of 300A.
For inverter use, select the complete system around appliance demand, including starting loads, conversion losses, cabling and protection. Stored capacity and maximum current are separate considerations when planning the installation.
A-Grade LiFePO4 Cells and Built-In BMS
Autory uses A-grade lithium iron phosphate cells with an integrated battery management system.
The BMS provides overcharge, over-discharge, temperature and short-circuit protection, together with cell balancing.
Metal Case and Integrated Mounting Brackets
The all-metal enclosure includes integrated brackets for securing the battery in its installation.
Dimensions are 380mm long × 188mm wide × 270mm high. The battery shares the 200Ah model’s listed width, with additional length and height accommodating its larger capacity.
IP67-Rated Enclosure
The enclosure is rated IP67 for dust and water ingress protection. The supporting laboratory report is available below, alongside the battery test report and accompanying compliance certificate.
Lithium-Compatible Charging
The listed charge voltage is 14.6V, with a maximum charging current of 300A.
Use mains chargers, solar controllers or DC–DC chargers compatible with the battery’s LiFePO4 charging requirements. Maximum charging current is a limit, rather than a required charging rate.

Download Test Reports and Compliance Documentation
The IEC report lists AT-12-300 among its model references and records testing performed on AT-12-200. It reports passing results for the assessed requirements, with battery-system safety analysis under clause 8.1 excluded from its scope.
The IP67 report lists the AT-12-200/100/235/300 model family and records passing ingress-test results for the submitted samples.

Three-Year Replacement Warranty
This battery includes a three-year return-to-base replacement warranty, subject to testing.
If the returned battery is confirmed faulty, a replacement battery will be supplied. Return freight to VanDIY is at the customer’s expense, and freight for the replacement is covered by VanDIY.
If testing finds no fault, the customer pays the freight to have the battery returned. Replacement batteries retain the balance of the original warranty period.
