Key Features

High-Efficiency 5.12kWh Energy Storage

Unlike standard 48V batteries that only offer 4.8kWh, the ECELL 51.2V 100Ah model delivers 5.12kWh of total energy. This higher voltage platform ensures better efficiency and compatibility with modern 48V/51.2V hybrid and off-grid inverters.

Triple-Protocol Communication (CAN/RS485/RS232)

Engineered for universal compatibility. The unit features dedicated CAN, RS485, and RS232 ports, allowing seamless integration with leading global inverter brands (e.g., Victron, Deye, Growatt, Goodwe). The dual RS485 ports support easy parallel communication.

Built-in DC Circuit Breaker for Extra Safety

Safety is visible. We have integrated a robust DC Circuit Breaker directly on the front panel. This provides physical over-current protection and allows for a safe, manual disconnect during maintenance—a superior safety feature compared to batteries with only a BMS soft-switch.

Smart Visual Monitoring

Stay informed at a glance. The front panel includes a precise LED SOC (State of Charge) Bar to display real-time battery levels, along with dedicated ALM (Alarm) and RUN status indicators for instant system health diagnostics.

Flexible Scalability (ADS Switch)

Growing energy needs? No problem. With the built-in ADS (Address Dip Switch) and parallel ports, you can easily connect multiple units in parallel to expand your storage capacity, making it perfect for both small residential setups and larger commercial projects.

Robust Rack-Mount Design

Housed in a durable metal enclosure, this standard 19-inch rack-mount design ensures easy installation in standard server cabinets or dedicated battery racks, keeping your setup clean, organized, and space-saving.

Strict Quality Control & Manufacturing

At ECELL BATTERIES, quality is not just a promise; it is our standard operating procedure. Every 51.2V 100Ah battery module undergoes a rigorous manufacturing process to ensure reliability and longevity.

• Grade A Cells Only: We strictly use brand-new, Grade A LiFePO4 cells to ensure consistent voltage and capacity.
• Precision Assembly: Our automated spot welding and laser welding technologies ensure low internal resistance and robust structural integrity.
• Comprehensive BMS Testing: The Battery Management System is tested for over-current, over-voltage, and temperature protection before integration.
• 100% Aging Test: Before shipment, every battery unit undergoes a complete charge-discharge aging test to verify actual capacity and performance stability.

Professional Packaging

UN38.3 Compliant Safety Packaging

We understand that Lithium Iron Phosphate batteries are classified as Dangerous Goods (DG, Class 9). To ensure your goods arrive safely and clear customs smoothly, we strictly adhere to international shipping regulations.

• UN Certified Cartons: Each battery is packed in a UN-certified heavy-duty carton box designed to withstand impact and vibration.
• Protective Foam Padding: High-density custom-molded foam surrounds the battery 360 degrees to prevent movement and shock damage during transit.
• Palletization for Bulk Orders: For volume shipments, cartons are stacked on fumigation-free wooden pallets, shrink-wrapped, and strapped for maximum stability during sea freight.
