Notes* Recommended charge current for best cell longevity. ¹ Cycle life independently laboratory tested at 0.2C₅ discharge rate and 0.2C charge rate up to 5,000 cycles at a controlled temperature of 25°C. Electronic logs recorded during testing show residual capacity in excess of 85% of nameplate C5 capacity after 3,000 cycles. In real-world conditions, users will experience a range of temperature, current and voltage conditions which may affect actual battery performance over its life. Lower depths of discharge and high continuous charge/discharge rates will reduce overall cycle life.

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.
