The Next Evolution: Gen 2 163S 163Ah LiFePO4 Battery

Ultra-Compact Design | 200A High-Output BMS | UN38.3 Certified | Cross-Capacity Parallel Ready | Australian Engineered

Redefine your power limits with the Generation 2 163S. This unit completely rewrites the rules of battery geometry by packing a massive 163Ah punch into a frame that is actually smaller than most standard 105Ah batteries on the market. Featuring a heavy-duty 200A Daly JHB Series Smart BMS, independent active cell management, and full UN38.3 transport certification, this 163Ah powerhouse delivers massive current from a tiny space—now with the flexibility to scale your system to any size safely, legally, and reliably.

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 163Ah 12VS battery gives you a full 163Ah of usable power right down to the low-voltage cutoff without dropping voltage or harming the cells.
• Half the Size, Twice the Power: Because you can use every single amp-hour, this ultra-compact powerhouse effectively replaces an AGM bank more than double its physical size and weight.

Unrivaled 200A Continuous Power

Despite its tiny footprint, this battery is a high-performance beast. The upgraded 200A Daly JHB Series BMS allows you to run high-draw appliances that standard 100Ah batteries simply can't handle. It is the ideal partner for 2000W to 2500W inverters:

• Induction Cooktops & Air Fryers: Full-power cooking without tripping the BMS.
• Coffee Machines & Kettles: Rapid boiling for your morning brew.
• Air Conditioning: Reliable startup current for cooling units.
• Starlink Mini & Tech: Stable, clean power for all your remote communication gear.

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 163Ah battery in parallel with a 12V 304Ah 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 the smaller pack is 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 163S 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 2608Ah power bank.
• Total Versatility: Perfect for everything from small camping setups to large-scale marine and residential energy storage.

Compact Design, Built for the Elements

Australian conditions are unforgiving. That’s why the Gen 2 163S is IP67-rated, making it completely dust-tight and capable of withstanding water immersion up to 1 meter. Whether it’s mounted in an open tray, a boat, or a canopy, it’s protected against the elements.

• Compact Footprint: Measuring an astonishingly compact 260mm (L) x 168mm (W) x 210mm (H) (230mm total height including terminals) and weighing just 14.7kg, this unit delivers unparalleled space savings. It slides easily into tight canopy corners, narrow 4x4 compartments, or compact caravan lockers where traditional 160Ah blocks never stand a chance.
• Lightweight & Tough: Premium CALB Grade A cells offer maximum energy density with minimal weight.

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 163S is a testament to quality, featuring top-tier components for maximum safety and a 10+ year service life:

• Grade A CALB Cells: Renowned globally for exceptional thermal stability, performance consistency, and unwavering reliability on rough outback tracks.
• 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.
• 200A 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: Working independently of the BMS, it actively equalizes cell voltages at a high 5A rate, ensuring optimal performance, preventing premature cell degradation, and significantly extending the overall lifespan of the pack.
• Bluetooth Monitoring APP: For detailed insights on your smartphone, connect via the official DALY BMS App. Download it here:
  • Apple App Store (iOS): DALY BMS Apple Store
  • Google Play Store (Android): DALY BMS Google Play Store
• 5-Year Warranty: Our absolute confidence in the 163S is backed by a comprehensive 5-year warranty, guaranteeing a reliable power solution for years to come.
