Product Description
The Ultimate Home Battery Backup Solution
The Balder Power 10kWh Wall Mounted LiFePO4 Battery is engineered for homeowners who demand more. As a professional Lithium Battery Manufacturer, we have optimized this 51.2V 200Ah system for residential solar energy storage and off-grid applications.
Why choose a 10kWh single module?
Installing one 10kWh unit is faster and more efficient than daisy-chaining two 5kWh units. It saves wall space, reduces connection points, and simplifies system monitoring.
Applications:
-
Self-Consumption: Store excess solar power during the day to power your home at night.
-
Backup Power: Keep essential appliances (lights, fridge, WiFi) running during grid outages.
-
Peak Shaving: Discharge during peak tariff hours to slash electricity bills.
Backed by UN38.3, CE, and MSDS certifications, this robust energy storage system is ready for global shipping.

Features & Advantages
High-Density 10kWh Powerhouse
Maximize your energy independence with the Balder Power 51.2V 200Ah Wall Mounted Battery. Delivering a massive 10.24kWh of usable energy in a single unit, it provides double the capacity of standard 5kWh modules. This means fewer units to install, fewer cables to manage, and a cleaner setup for high-demand households.
Robust Industrial Design & Safety
Safety dictates design. Unlike thinner, plastic-heavy alternatives, our 10kWh unit features a thickened, heavy-duty metal enclosure. This robust design is engineered to:
- Provide superior physical protection for the high-capacity 200Ah cell pack.
- Ensure optimal thermal management and heat dissipation, keeping the BMS and cells cool even under heavy loads.
- Prevent casing deformation over years of operation.
Universal Inverter Compatibility
Our intelligent BMS acts as the brain of your solar system. Featuring dual CAN/RS485/RS232 communication ports, it is pre-programmed to work seamlessly with leading global hybrid inverters, including Victron Energy, Deye, Growatt, GoodWe, LuxPower, SMA, and Solis.
Automotive-Grade LiFePO4 Cells
We refuse to compromise on quality. Built with Grade A Lithium Iron Phosphate (LiFePO4) prismatic cells, this battery offers exceptional thermal stability and zero risk of thermal runaway. With a cycle life exceeding 6,000 cycles at 80% DOD, it is designed to serve your home for over 15 years.
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.

FAQ
Frequently Asked Questions
Q: How many 10kWh batteries can I connect in parallel?
A: The Balder Power 51.2V 200Ah battery supports parallel connection of up to 15 units. This allows you to expand your system capacity from 10kWh up to a massive 153kWh, suitable for large luxury homes or small commercial businesses.
Q: Why is the 10kWh unit thicker than the 5kWh model?
A: The 10kWh model houses double the capacity of battery cells (200Ah). To ensure safety, longevity, and proper heat dissipation, we utilize a robust, widened metal casing. This ‘thick’ design prevents overheating and ensures the structural integrity of the heavy cell pack.
Q: What is the recommended charging current for this 200Ah battery?
A: For optimal lifespan, we recommend a standard charge current of 40A-100A (0.2C – 0.5C). The maximum continuous charge/discharge current is 100A, capable of supporting high-power loads.
