The Slimline Revolution: Gen 2 163SL 163Ah Slimline LiFePO4 Battery

Slimline Design | 200A High-Output BMS | UN38.3 Certified | UL1642 & IEC 62619 Certified Cells | Cross-Capacity Parallel Ready | Australian In-House Engineered

Are you constantly battling for space in your setup but refuse to compromise on performance? This is not a generic mass-produced import—it has been meticulously designed and engineered right here in-house specifically for the brutal extremes of the Australian environment. The groundbreaking 163SL 163Ah Slimline LiFePO4 battery is the ultimate answer. We’ve packed an astonishing 163 amp-hours of deep-cycle power into a narrow footprint typically reserved for standard 100Ah slimline blocks, redefining what’s possible for space-constrained installations. Featuring a heavy-duty 200A Daly JHB Series Smart BMS, independent active cell management, UL1642 and IEC 62619 certified cells 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

The 163SL is a true game-changer. Boasting a formidable 200A continuous output, this battery is the ideal partner for your 2000W to 2500W inverter. It provides enough "grunt" to run all your high-demand appliances and modern tech simultaneously, with absolutely zero voltage sag:

• 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 slimline 12V 163Ah battery in parallel with a 12V 304Ah block 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 163SL 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 163SL features a rugged layout built to optimize space while remaining protected against the elements.

• Slimline Footprint: Prepare to be impressed by its dimensions: 395mm (L) x 110mm (W) x 285mm (H). Weighing in at just 14.7kg, the 163SL sets a new benchmark for energy density. This narrow, sleek design allows it to effortlessly slide into tight spaces—making it the ultimate choice for behind-the-seat installations in dual-cab 4x4s, tight canopy false floors, cramped caravan compartments, or discreet marine side-pockets. It matches the physical size of most standard 105Ah slimlines on the market while delivering over 50% more runtime.
• 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 163SL is a testament to quality, featuring top-tier components for maximum safety and a 10+ year service life:

• In-House Australian Engineering: Custom-architected locally to survive corrugated outback tracks, extreme heat, and rigorous off-grid demands—not a generic off-the-shelf factory box.
• Grade A CALB Cells (UL1642 & IEC 62619 Certified): Built using globally recognized cells certified to UL1642 and IEC 62619 safety standards, renowned for exceptional thermal stability, rigorous overcharge protection, and unwavering reliability on rough outback tracks.
