Description

REVOLUTIONIZE YOUR POWER MANAGEMENT WITH ALLSPARK BLUETOOTH TECHNOLOGY

The Pro-Series 300Ah slimline lithium battery from AllSpark is built for Australians who are tired of flat batteries, fridge dramas and confusing setups. Designed by Offroad Living for serious off-grid touring, this 12V 300Ah LiFePO4 battery delivers massive usable capacity, true 300A continuous output and integrated Bluetooth monitoring - without the need for external shunts or add-ons.

Inside, we use brand-new A-Grade prismatic cells - not recycled or second-hand cells often found in cheaper batteries. That means consistent performance, reliable cycle life and long-term confidence. Housed in a slimline aluminium case and backed by a 7-year full replacement warranty, this battery is engineered to power large inverters, big fridges and demanding 12V systems across Australia’s harshest conditions.

Real Bluetooth Monitoring. $0 Extra.

External monitors cost hundreds to buy and install, and their innacuracies can be frustrating.

The in-built Bluetooth monitoring via the AllSpark app offers:

Direct BMS integration - offering accurate monitoring at all times, from the start, no "syncing" required
Individual cell voltage monitoring - track the automatic cell balancing to ensure longevity & optimal performance
Lifetime history tracking - not limited to ~30 days
Switch on & off in the App - without the need for an external Master Switch

No external shunts. No $200+ add-ons. Just real data straight from your 300Ah slimline lithium battery.

Engineered for Australian Conditions

Heat, corrugations and vibration destroy average batteries. Every AllSpark battery undergoes multi-frequency prolonged vibration testing, designed to simulate the effects of driving thousands of kilometres of corrugated roads, meaning our batteries are literally built for Aussie conditions. AllSpark batteries are built specifically for Australian off-road touring and include:

high and low temperature protection
active cell balancing
reverse polairty protection
slimline powder-coated aluminium case
IEC 62619 Certified (AS/NZS 3001:2022 compliant applications)

Runs a 3000W Inverter on a Single Battery

A single 300Ah slimline lithium battery delivers the output required to confidently run a 12V 3000W inverter, without needing a multi-battery bank just to handle surge loads. With 300A continuous output (600A peak), it’s engineered for high-demand appliances that typically push most batteries to their limits.

That means you can run induction cooktops, air fryers, kettles, toasters, coffee machines and caravan air conditioners (even multiple at once!). Instead of worrying whether your battery can handle the surge, you’re building a system designed for serious 240V use off-grid.

Built for Real Camping Loads

The most common failure story? “Fridge + overnight = flat battery.” The AllSpark 300Ah lithium battery is built as a true “set and forget” solution for serious off-grid touring.

We always recommend sizing your battery bank to handle at least two days without solar input - because cloudy weather happens. With the 300Ah AllSpark, a single battery can comfortably run a large upright fridge, and a second draw fridge or freezer, along with high-powered appliances (such as induction cooktops, coffee machines and toasters) and typical loads like LED lighting and phone charging for two days.

Instead of constantly managing power, you’re building in headroom, so your system works even when conditions aren’t perfect. Ideal for extended off-grid setups and fully scalable with unlimited parallel connections, this is about designing so power isn't something you have to think about. .

Dual Terminals. No Extra Busbars.

Higher loads bring more connections to your battery, and that often means adding busbars, because stacked lugs can cause voltage drop and unreliable connections.

The AllSpark 300Ah slimline lithium battery features dual terminals (2x positive, 2x negative), allowing cleaner cable routing and proper separation of high-draw loads like a 3000W inverter, keeping your install neater, simpler and built for serious current flow - without the extra hardware.

What's in the box:

1 x 12V 300Ah LiFePO4 Battery with Bluetooth
4 x M8 terminal bolts (25mm & 18mm)
Integrated flat & spring washers
Red & black terminal caps + full terminal covers

IEC 62619 Certification

FAQS

Q: Is this battery certifed for use in Caravans?

A: Yes - AllSpark batteries are not only compliant, but are actually "Tested" and "Certified" for compliance with IEC 62616 standards (see downloads for certificate). Many sellers of LiFePO4 batteries in Australia claim to be "compliant" with the IEC 62616 standards, but have never actually had them tested or hold any certification for this compliance. Self claiming compliance with a standard without 3rd party certification is not only misleading, but is fraudulant advertising practices.

Q: How do I store my AllSpark LiFePO4 battery?

A: If you plan to have your batteries in storage for extended periods of time, disconnect/isolate any loads or parasitic power consumers. Charge/Discharge battery to 80% State of Charge. Battery can then be stored for up to 12 months. If storing for longer, re-charge to 80% SoC every 6-12 months.

Q: Can I install my AllSpark Slimline Battery on it's side?

A: Yes - you can install all AllSpark slimlines batteries on their side.

Q: What do I do if my AllSpark LiFePO4 battery goes flat?

A: If you discharge your battery to 0% (10.5V or less), it will enter Low voltage protection mode. This will disconnect all loads and the battery and terminal voltage will show as 0-3V. When in LV protection mode, the BMS disconnects power to the battery terminals. To release it you simply open the AllSpark Bluetooth App on your smart device, turn the discharge function back to ON and let your charger take over. Most other brands need a "jump start" or external charger input or parallel connection to wake it up. AllSpark Lithium batteries are much smarter and simpler to wake up for charging. Note: if you don't have a charge source ready, it will go back to sleep again after a short time to protect the cells until you are ready to re-charge.

Q: Will a 300Ah lithium battery run my fridge overnight?

A: Yes - and that’s exactly what it’s designed for, running fridges and appliances confidently so you don't have to think about power. One of the most common off-grid failure stories in Australia is “fridge + overnight = flat battery” . With 300Ah of usable LiFePO4 capacity, this battery is built to comfortably run large 12V fridges, plus LED lighting and device charging, without waking up to a low-voltage scramble.

Q: Can a single 300Ah battery run a 3000W inverter?

A: Yes - this 300Ah lithium battery delivers 300A continuous output (600A peak), allowing it to run a 12V 3000W inverter. That means induction cooktops, kettles, air fryers, coffee machines and even caravan air conditioners are realistic loads — not “wishful thinking” loads. Multiple appliances can be run together as long as total draw stays within inverter limits.

Q: Do I need a DC/DC charger with a 300Ah lithium battery?

A: We always recommend using a DCDC charger. DCDC chargers help keep your batteries topped up whilst driving, which is especially important when the sun isn't shining.

Q: Is lithium safe in caravans and 4WD setups?

A: Yes - LiFePO4 batteries are a very different chemistry than those lithium batteries you see causing fires and spontaneously combusting. The are designed with multiple protection systems and are not capable of thermal runaway - meaning, they will burn (just as an AGM, Calcium, Lead Acid etc), but they aren't capable of starting a chain reaction themselves. As with any electrical system, correct installation and charging practices are critical, because it won't be the lithium battery that starts a fire, it'll be the dodgy wiring, cheap circuit protection or loose connections.
