The Next Evolution: Gen 2 304-CAN 304Ah LiFePO4 Battery

Ultra-Compact Design | 300A High-Output BMS | UN38.3 Certified | Cross-Capacity Parallel Ready | Integrated CAN/RS485 Communications | Australian Engineered

Redefine your power limits with the Generation 2 304-CAN. This unit completely rewrites the rules of battery geometry by packing a massive 304Ah punch into a compact frame that effortlessly slides into tight canopy corners, caravan lockers, or marine compartments. Engineered in our workshop in Welshpool, Western Australia, it features a heavy-duty 300A Daly JHB Series Smart BMS, integrated CAN/RS485 communication protocols, independent active cell management, and full UN38.3 transport certification. This powerhouse doesn't just store energy—it integrates directly with your premium electronics to deliver a professional-grade, closed-loop energy system.

100% Usable Capacity — Power Every Last Amp

Unlike traditional AGM or lead-acid batteries that damage themselves if discharged past 50%, 12VS Gen 2 Lithium batteries deliver 100% usable capacity.

• Get What You Pay For: A 304Ah 12VS battery gives you a full 304Ah of usable power right down to the low-voltage cutoff without dropping voltage or harming the Grade-A+ cells.
• Half the Size, Twice the Power: Because you can use every single amp-hour, a single compact 12VS battery effectively replaces an AGM bank more than double its physical size and weight.

Unrivaled 300A Continuous Power

Despite its compact footprint, this battery is a high-performance beast. The upgraded 300A Daly JHB Series BMS allows you to run high-draw appliances that standard lithium batteries simply can't handle. It is the ideal partner for 3000W to 3500W inverters, feeding massive loads without breaking a sweat:

• Induction Cooktops & Air Fryers: Full-power, chef-grade cooking without tripping the BMS.
• Coffee Machines & Kettles: Rapid boiling for your morning ritual, uncompromised.
• Air Conditioning: Reliable startup and runtime current for true off-grid climate control units.
• Starlink Mini & Tech: Stable, clean power for high-speed internet across the Nullarbor.
• Heavy-Duty Tools: Run air compressors, power tools, or high-output chargers with ease.

The "Victron-Ready" Advantage

Why settle for estimated battery percentages? The 608-CAN features dedicated CANbus and RS485 ports engineered for seamless integration with premium power management ecosystems.

• Direct GX Device Integration: Use a 12VS CAN-bus BMS Cable to link your primary battery directly with your Victron GX device (such as the Cerbo, Ekrano, or Venus). This establishes the master data link for the entire installation.
• Full System Visibility: View your precise State of Charge (SoC), live current draw, cell voltages, and battery health through your Victron touchscreen or remotely via the global online VRM Portal.
• True Closed-Loop Control: Your battery establishes a continuous digital handshake with the GX device. The GX device then automatically coordinates and commands your MultiPlus, Quattro, or SmartSolar MPPT controllers. This system-wide loop allows the BMS to dynamically dictate real-time charging limits, preventing over-voltage and maximizing cell longevity.
• Smart Parallel Networking: Seamlessly link multiple internal BMS units together using standard RJ45 UTP cables to sync data across the entire bank, ensuring balanced performance and unified system communication.

Revolutionary Cross-Capacity Paralleling Permitted

Traditional engineering rules say you can never mix lithium battery sizes in parallel—the Gen 2 JHB Series completely shatters that rule.

• Integrated JHB Parallel Current-Limiting Modules: Your integrated Daly JHB Smart BMS is manufactured with an onboard intelligent parallel current-limiting module. When multiple 12VS batteries are connected to form a common bank, the JHB hardware automatically detects any state-of-charge or voltage differences between the packs. If a voltage delta exists, the BMS instantly engages its inline current-throttling circuitry, safely capping the cross-pack current transfer to a pre-set internal limit while the batteries smoothly align themselves automatically.
• Mix & Match Capacities: You can safely mix and match different battery capacities within the 12VS parallel lineup (e.g., connecting this 12V 304Ah battery in parallel with a smaller 12V 105Ah or 163Ah battery on the same single Busbar), provided they share the same series BMS architecture.
• How it Works: The internal parallel modules dynamically throttle and balance current distribution based on each battery’s individual capability. The larger pack safely shoulders a proportionally larger share of the system load, while smaller packs are fully protected from over-stress.

Infinite Scalability: Series & Parallel Ready

Whether you need a simple 12V setup or a massive off-grid bank, the Gen 2 304-CAN is built to grow with you.

• 4S Capability: Connect up to 4 units in series for 24V, 36V, or 48V systems.
• 16P Capability: Connect up to 16 units in parallel to create a massive 4864Ah power bank.
• Total Versatility: Perfect for everything from custom canopy builds and motorhomes to large-scale marine vessels and residential energy storage systems.

Compact Design, Built for the Elements

Australian conditions are unforgiving. That’s why the Gen 2 304-CAN is built into a ultra-rugged layout designed to withstand vibration and dust while maximizing every millimeter of space.

• Beyond Compact: We've squeezed a massive 304Ah capacity into a frame measuring just 345mm (L) x 190mm (W) x 272mm (H). At only 28kg, it is roughly the same footprint as a traditional 120Ah AGM battery but delivers more than double the usable energy.
• Lightweight & Tough: Premium EVE Grade A+ cells offer maximum energy density with minimal weight, making it the ultimate space-saving choice.

AS/NZS 3001.2:2022 Ready (Installer Compliant)

Our batteries are engineered to meet the strict structural, terminal security, and cell isolation benchmarks required by the latest Australian/New Zealand standards for habitable vehicles and marine craft.

Important Installation Note: To fully comply with AS/NZS 3001.2:2022, if this lithium battery is installed within a habitable location of a caravan, motorhome, or camper, it must still be housed within a sealed enclosure that vents directly to the outside of the vehicle.

Premium Engineering & Intelligent Management

Every Gen 2 304-CAN is a testament to quality, featuring top-tier components for maximum safety and a 10+ year service life:

• Grade A+ EVE Cells: We utilize genuine EVE LF304 prismatic cells, factory-matched for internal resistance and capacity. Rated for 3,500 to 6,000 cycles, these industry-leading cells offer exceptional thermal stability essential for maintaining peak performance in high-ambient-temperature environments.
• UN38.3 Certified Safety: Fully tested and certified for safe transport and vibration resistance, ensuring the internal cell architecture stands up to corrugated outback tracks and rigorous shipping conditions.
• 300A Daly JHB Smart BMS: A heavy-duty, commercial-grade Battery Management System that protects against overcharge, heat, and short circuits while effortlessly handling massive current loads.
• Separate Heltec 5A Active Balancer: Most batteries rely on tiny 30–50mA passive balancing that only operates at the very top of the charge cycle. We include a dedicated 5A Heltec Active Balancer that physically transfers energy from the highest cells to the lowest cells 24/7, keeping the bank perfectly balanced even under massive 300A discharge loads.
• Dual-Path Monitoring: Get complete visibility into your system. Use the official Bluetooth App for a deep dive into individual cell voltages and BMS temperature sensors when you are near the vehicle, or let the Victron GX integration push your data to the VRM Portal for remote system health monitoring from anywhere in the world.

Why the 304-CAN is the Professional's Choice: By combining a massive 304Ah capacity with high-speed active balancing and advanced digital communication protocols, we've eliminated the two biggest threats to lithium longevity: cell drift and "dumb" uncoordinated charging. Whether you're configuring a commercial marine vessel, an off-grid home, or a serious 4x4 canopy setup, the 304-CAN delivers the intelligence of a high-end commercial server rack in a portable, ruggedized, outback-ready form factor.
