Shop Affordable Battery & Power Supplies

Whether you're heading off-grid, powering a caravan setup, or building a backup system at home, having a reliable power source makes the difference. Our range of cheap batteries and power supplies includes deep cycle AGM and lithium batteries in various capacities, pure sine wave power inverters for 12V DC to 240V AC conversion, and a solar charge controller for off-grid charging. Products suit camping, caravanning, marine, and home backup applications. When choosing cheap batteries and power supplies, the right selection depends on how much power you need to store, what you plan to run, and how you recharge. Our solar panels are the natural companion for deep cycle batteries off-grid, and our caravan accessories has the fitting and storage hardware that pairs with a 12V power setup on the road. Every order ships fast across Australia with a 12-month warranty and 7-day support.

Deep Cycle Batteries: AGM vs Lithium LiFePO4

Deep cycle batteries make up the majority of the range and are designed for sustained, repeated discharge and recharge cycles, unlike standard starter batteries built for short high-current bursts. Two chemistries are available: AGM and lithium LiFePO4. AGM is the more common starting point and offers reliable performance across a range of temperatures with no maintenance required. Lithium LiFePO4 options are lighter and typically deliver more usable capacity for the same rated Ah, which suits weight-conscious setups like caravan or portable camping applications. Capacity is measured in amp-hours (Ah), and choosing a figure that comfortably covers your expected draw without fully discharging each cycle is the standard recommendation. For camping and outdoor gear that draws power from a portable battery system, our camping accessories has the selection that pairs with a 12V setup. For extended off-grid trips where portable power is central to the experience, our camping outdoor brings together the gear that supports multi-day adventures.

Power Inverters and Converting 12V to 240V

Power inverters in this range convert 12V DC battery power to 240V AC, allowing you to run standard household appliances and tools from a battery system. The products are pure sine wave inverters, which produce a clean AC output suitable for sensitive electronics and appliances that need stable voltage. Wattage is the key specification: the inverter's continuous wattage needs to exceed the combined draw of all devices you plan to run at once, with surge wattage covering the brief spike when devices start up. The range covers a broad spread of continuous wattage options for different applications. For vehicle and off-road touring setups where a 12V power system runs alongside other accessories, our automotive accessories has the broader vehicle gear that complements a portable power setup. For 4x4 and touring applications where a battery and inverter form part of an off-grid vehicle build, our 4x4 accessories brings together the touring equipment that pairs naturally with portable power.

Solar Charge Controllers and Off-Grid Charging Systems

The MPPT solar charge controller in this range manages the charging process between solar panels and a battery bank, optimising energy conversion and protecting batteries from overcharging. MPPT controllers are more efficient than older PWM designs at converting panel voltage into usable charging current, which means more energy from the same panel setup. The controller available supports multiple voltage configurations, making it compatible with various battery bank sizes. Pairing a charge controller with deep cycle batteries and solar panels creates a self-contained off-grid charging system suited to both permanent installations and portable setups. For outdoor security lighting systems that benefit from solar charging and battery backup, our outdoor lighting has the solar-powered options that integrate with an off-grid power setup. For gate opener systems that use solar panels and need reliable battery backup, our gate openers has the automated entry options that run on the same off-grid charging principles.

Marine, Caravan, and Off-Grid Applications

The products in this range are designed with portability and varied applications in mind. The batteries are described for solar, caravan, and camping use, reflecting their intended role: overnight and multi-day trips away from mains power, whether by caravan, boat, or campsite. The car battery charger in the range handles 12V battery maintenance to keep batteries ready between uses. Power inverters in the range list camping, car, and boat as intended environments, indicating units built for movement and varied conditions rather than stationary home backup alone. For marine and waterway recreational use where 12V battery power is central to the day, our boating accessories has the marine gear that works alongside a portable power system. For the broader outdoor adventures and activities that depend on portable power, our outdoor activities brings together the gear suited to off-grid exploration.

Why Shop at Factory Buys

Reviewers on Trustpilot rate Factory Buys for fast delivery and inexpensive prices on gear that performs when it matters most. Every order comes with a 12-month warranty, and our support team is available from 8am to 8pm, seven days a week if anything needs following up after delivery.

What output ports and connections should I check before I buy?

Make a quick list of what you want to power, then match it to the outputs on the product listing. Check the number and type of ports, plus any limits on how much you can run at once. If you will use multiple devices, prioritise a model with enough outputs so you are not relying on adapters.

How do I decide between a compact option and a higher capacity one?

Choose compact if you want something easy to carry, store, and move between the car, shed, or campsite. Go higher capacity if you want longer run time between charges or you will use it more often. If you are also building an off grid setup, Solar panels can be a sensible next step.

Will it fit your battery box and connect to your current cables?

Measure your battery box internal dimensions and compare them to the battery’s listed length, width, and height. Also check terminal type and placement so your current cables reach without strain. If you are replacing a battery, match the physical size and terminal orientation to avoid cable extensions or tight bends.

How do I choose the right battery power supply for my usage?

Start with where you will use it, such as camping, a vehicle, or backup at home, then think about how long you need it to run between charges. If you are unsure, choose products with clear intended use notes and inclusions on the listing. If you want a broader view of options, power supplies can help you compare what suits your needs.

What warranty and returns apply if power gear arrives faulty or damaged?

All orders are dispatched from our warehouse within 1 to 2 business days. Delivery typically takes 1 to 12 business days, depending on your location and the courier. All products include a 12 month warranty, and our Customer Support team is available 8 am to 8 pm, 7 days per week.
