Product Description
Maximize Your Energy Storage with the 14.3kWh Powerhouse
The Balder Power 51.2V 280Ah Server Rack Battery represents the next generation of lithium energy storage. Engineered for commercial and high-demand residential applications, this 14.3kWh module redefines energy density.
Why Upgrade to 280Ah?
Traditional setups require connecting multiple 100Ah batteries to achieve high capacity, leading to messy wiring and potential balance issues. Our 280Ah module solves this by packing 14.3kWh into a single unit. You can build a massive 229kWh system by paralleling just 16 units, saving valuable server rack space and installation labor time.
Industrial-Grade Reliability
At its core, we use A-Grade LiFePO4 prismatic cells—the same technology found in electric vehicles. Combined with our proprietary Smart BMS (Battery Management System), the battery is actively protected against overcharging, over-discharging, and temperature extremes. The built-in display provides real-time diagnostics, ensuring your system operates at peak efficiency.
Whether for solar self-consumption, peak shaving, or critical backup power, this battery delivers consistent, safe, and scalable power.

With a lifespan of over 6000 cycles, the cost per kWh over the battery’s life is significantly lower than lead-acid or standard lithium options. -
🔌 Universal Compatibility
Pre-programmed to communicate with 90% of mainstream hybrid inverters on the market via CAN/RS485 ports. -
📈 Seamless Scalability
Support up to 30 units in parallel (depending on inverter), allowing your system to grow from 14kWh to over 400kWh without changing the central architecture.
Manufacturing & QC Process
Precision Engineering: Our Energy Storage Battery Manufacturing Process
Quality is not just inspected; it is manufactured at every step. At Balder Power, we implement a rigorous LifePO4 production protocols that goes beyond industry standards. From automotive-grade cell sorting to 100% full-cycle aging tests, our transparent manufacturing process ensures every Energy Storage System (ESS) delivers maximum safety and longevity for your projects.
Custom Engineering & ODM Design
Our Wuhan engineering team translates your voltage and capacity requirements into precise CAD blueprints. We simulate structure and thermal management to ensure the battery pack fits your application perfectly before production begins.
Premium A-Grade Cell Sourcing
Quality starts at the core. We strictly select brand-new, A-grade LiFePO4 or NCM cells from Tier-1 manufacturers (like CATL, EVE, Ganfeng). We match cells specifically for your project's energy density and cycle life needs.
Precision Capacity & IR Sorting
To guarantee pack longevity, consistency is key. We utilize automated sorting machines to group cells with identical Internal Resistance (IR) and Voltage. This strictly eliminates the "barrel effect," ensuring the entire pack performs at peak efficiency.
Automated Matrix Spot Welding
Our robotic welding arms execute high-precision spot welding using pure copper strips. This process ensures low-impedance connections and structural rigidity, preventing vibration damage during transportation or mobile usage.
Smart BMS Integration & Wiring
The "Brain" of the battery is installed. We integrate advanced Battery Management Systems (BMS) with communication protocols (CAN/RS485). Technicians organize signal wires neatly to prevent short circuits and ensure accurate thermal monitoring.
Structural Assembly & Insulation
Before closing the case, we apply industrial-grade insulation and shock-absorbing materials. The semi-finished packs are inspected for layout integrity to meet IP protection ratings for dust and moisture resistance.
100% Aging Cycle Test & OQC
Zero tolerance for early failures. Every finished battery undergoes a rigorous aging test (Charge/Discharge cycles) to simulate real-world stress. Final OQC includes voltage checks, BMS communication tests, and visual inspection.
UN38.3 Compliant Safety Packaging
Safety extends to delivery. We use customized wooden crates and high-density foam that meet UN38.3 dangerous goods transport standards, ensuring your goods arrive safely via sea or air freight.
Packing & Delivery
Secure & Compliant Packaging
To ensure safe transit for Class 9 Dangerous Goods, every battery is protected with high-quality Pearl Wool (EPE Foam) and encased in UN-certified cartons. For bulk shipments, we utilize sturdy Plywood or Plastic Pallets wrapped in shrink film, fully compliant with international shipping regulations.
Global Shipping Options (Incoterms)
We support flexible shipping terms to suit your business needs, including FOB, CIF, and DDP (Door-to-Door including tax).
