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.
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.

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.
