Product Description
Empower Your Energy Independence with Balder Power’s 10kWh Rack Battery
The Balder Power 51.2V 200Ah LiFePO4 Server Rack Battery is the ultimate energy storage solution for residential solar systems, commercial UPS, and off-grid setups. Designed to fit standard 19-inch server cabinets, this 10.24kWh module offers a high-density power solution without the bulk of traditional lead-acid batteries.
Seamless Expansion & Scalability
Grow your energy storage as your needs increase. Our “Scalable” design allows installers to connect up to 15 battery modules in parallel. Whether you need a 10kWh system for a smart home or a 150kWh bank for a small factory, this battery adapts effortlessly without complex rewiring.
Safety First with Smart BMS
Safety is non-negotiable. Each unit is equipped with an advanced Battery Management System (BMS) that actively balances cells and protects against over-voltage, under-voltage, short circuits, and extreme temperatures. The integrated front-panel display gives users real-time insights into voltage, current, and State of Charge (SOC).
Why Choose Balder Power?
As a dedicated Lithium Battery Manufacturer, we ensure every unit undergoes rigorous aging tests before shipment. We offer full OEM/ODM customization—from casing color to BMS protocol adjustments—helping you build your own brand in the local market.

Features & Advantages
🔌 Plug-and-Play Installation
Designed with standard 19-inch rack mounting ears and quick-terminal connectors. Reduces installation time by 40% compared to wall-mounted units.
🔋 Grade A LiFePO4 Cells
We use only top-tier Lithium Iron Phosphate cells from major manufacturers (CATL/EVE/Gotion), ensuring high consistency and a lifespan of over 6000 cycles.
📡 Universal Inverter Compatibility
Pre-loaded with protocols for 95% of the market’s inverters (Victron, Pylontech, Goodwe, Growatt, etc.). Simple dip-switch settings allow instant matching.
🌡️ Intelligent Thermal Management
Built-in temperature sensors monitor cell conditions in real-time. The system automatically cuts off during low-temp charging to prevent lithium plating and permanent damage.
📊 LCD Visual Monitoring
A user-friendly LCD screen on the front panel displays critical data including SOC, pack voltage, and alarm status, eliminating the need for external meters.
🏗️ Robust Metal Enclosure
Housed in a durable, industrial-grade metal casing that provides excellent heat dissipation and physical protection against impact and vibration.

FAQ
Q: Can I mix this 51.2V 200Ah battery with other 48V batteries?
A: It is highly recommended to use batteries of the same brand, capacity, and voltage. Mixing different chemistries or old/new batteries can degrade system performance.
Q: What is the difference between 48V and 51.2V?
A: 51.2V is the nominal voltage for a 16-cell (16S) LiFePO4 series, whereas “48V” is often a general term. Our 51.2V design is fully compatible with all 48V inverter systems and offers better efficiency.
Q: How do you ship these heavy batteries?
A: These are UN3480 Class 9 Dangerous Goods. We ship via specialized sea freight (DDP/DDU) with proper UN38.3 and MSDS documentation to ensure smooth customs clearance.
Q: Does this battery support communication with Victron inverters?
A: Yes, our BMS supports CAN bus communication perfectly compatible with Victron GX devices (Cerbo GX, etc.), allowing full system integration.
