Description

400AH OF CERTIFIED LITHIUM POWER - FOR TOURERS WHO REFUSE TO COMPROMISE

For serious off-grid touring, the AllSpark 400Ah 12V is the chassis mount battery box built to go the distance. IP67 rated, IEC 62619 certified as a complete battery, and designed around new 2025-generation premium A-Grade prismatic cells, this 400Ah lithium battery delivers the capacity and peak current output that extended trips demand.

Engineered in Australia by Offroad Living, the powder-coated stainless steel housing mounts directly to your chassis rail - sitting above the frame's lowest point to preserve your full ground clearance on corrugated outback tracks and creek crossings. Bluetooth monitoring is fully integrated into the BMS, so you get precise cell-level data from your phone at no extra cost.

Whether you're running multiple appliances, extended off-grid stints, or a motorhome electrical system, the 400Ah gives you the headroom to do it without rationing power.

400Ah Under Your Van - Without Losing Clearance

Serious off-grid builds need serious battery capacity. But adding a chassis mount battery box shouldn't mean sacrificing the ground clearance you need for the tracks you're heading to.

The AllSpark 400Ah is designed to sit above the frame rail, with built-in mounting points, allowing for it to be installed securely above the frames lowest point - no reduction in clearance, no compromise on the terrain you can tackle.

IEC 62619 Certified - Complete Battery

Ask your battery supplier for their IEC 62619 certificate and pay close attention to what it covers. Some only certify the cells, maybe the BMS, maybe it's crickets when asked the question.

Every AllSpark battery is fully certified for the complete battery - BMS, cells, housing, workmanship - meeting the IEC 62619 certification standard.

For a 400Ah lithium battery this size, that level of independent certification isn't optional, it's essential.

Manage 400Ah From Your Phone - At No Extra Cost

With 400Ah of capacity in your system, knowing exactly what's going on inside the battery matters. AllSpark's built-in Bluetooth monitoring delivers cell-level data, cycle history, charge and discharge tracking, and BMS status - directly to your phone.

This chassis mount battery comes fully enclosed in a tough stainless steel casing, meaning you also don't have to fork out for a flimsy caravan battery box, adding another $100+.

No separate monitor, no extra wiring, no extra installation costs. Just accurate data, always available.

Heavy-Duty BMS - Designed for Australian Conditions

A 400Ah IP67 lithium battery mounted under a motorhome needs a BMS that can handle the demands placed on it.

The AllSpark BMS protects against temperature extremes (-20°C to +60°C), over-voltage, under-voltage, over-current, short circuit, and reverse polarity. Automatic cell balancing maintains longevity across the full pack.

Laser-welded busbars mean the cell connections stay solid through thousands of kilometres of corrugations.

Run a Full 3000W Inverter - From One Battery

A single AllSpark 400Ah 12V has the continuous current output to run a 3000W inverter. Kettle, induction cooktop, toaster, caravan aircon - the kind of appliances that make off-grid feel like home.

Premium A-Grade prismatic cells rated at 200A continuous and 500A peak mean the power stays solid under load, without the voltage sag that cheaper cells deliver when it matters most.

1 x AllSpark Bluetooth 400ah powder coated stainless steel cased LiFePO4 battery with vent
M8 terminal bolts (2 length bolts) + nut covers

Notes* Recommended charge current is for best cell longevity. ^# Cycle life independently laboratory tested at 0.25C discharge and 0.25C charge rate to 5000 cycles at 25°C controlled temperature. Electronic logs recorded during testing show residual capacity in excess of 85% of nameplate C5 capacity after 3000 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.

FAQS

Q: I have received my battery, how do I turn it on and connect the Bluetooth?

A: Download the AllSpark App (see the Downloads section in your battery's listing, or enter "AllSpark" into the Google Play Store or the Apple App Store), then ensure your "location services" and bluetooth is turned on. You will see your battery appear in the list under "Bluetooth" - click on here, this will take you to the Dashboard screen. Scroll to the bottom and turn the Charge Switch and Discharge Switch on as required.

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: What is Current In/Out Net Value?

A: The Net Value is all the charge sources minus all the loads

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: Can I link another 400ah to give me 800ah? Or more?

A: Yes - these batteries can be connected in parallel using the second connector to double your amp hour capacity. The maximum that can be connected in parallel is 4 batteries. The batteries should be within a few months of each other in age to ensure optimal performance and longevity.

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 practises.
