The Next Evolution: Gen 2 105S 105Ah 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 105S. We’ve taken our most popular compact footprint and supercharged the internals. Featuring a heavy-duty 200A Daly JHB Series Smart BMS, independent active cell management, and full UN38.3 transport certification, this 105Ah 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 105Ah 12VS battery gives you a full 105Ah 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 twice its size and weight.

Unrivaled 200A Continuous Power

Despite its compact size, 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 & 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 105Ah 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 105Ah 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 105S 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 1680Ah 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 105S 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: At just 260mm (L) x 168mm (W) x 210mm (H), it fits in tight spaces where other 100Ah+ batteries won't, maximizing every millimeter of space in your caravan, canopy, or boat.
• Lightweight & Tough: Premium EVE 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 105S is a testament to quality, featuring top-tier components for maximum safety and a 10+ year service life:

• EVE Grade A+ Cells: The gold standard in lithium technology for longevity and safety.
• 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 105S is backed by a comprehensive 5-year warranty, guaranteeing a reliable power solution for years to come.
• Battery Monitor Configuration: If using a Victron SmartShunt or BMV-712 Battery Monitor, settings can be found here: Victron SmartShunt / BMV Settings.

Stop compromising on power or space. Embrace the ultimate freedom with the 105S 105Ah Small LiFePO4 battery. Compact, powerful, certified safe, and now IP67 rated for any adventure. Get ready to power your world, come rain or shine!

NOTE: Generation 2 Batteries are not compatible with Generation 1 Batteries and cannot be connected together in series or parallel.
