This product includes only the battery case, BMS, and accessories. Battery cells are sold separately.

Our premium battery kit is engineered for 16 cells in series configuration, creating the foundation for a robust 51.2V energy storage system. Simply select the matching prismatic cells to achieve your desired capacity.

Capacity Options:

• 280Ah Cells: Build a 14.34 kWh battery pack - ideal balance of performance and cost-effectiveness
• 304Ah Cells: Create a 15.56 kWh battery pack - significant capacity upgrade in same footprint
• 314Ah Cells: Maximize storage with 16.08 kWh - premium solution for demanding energy needs

System Architecture: Total energy calculated as Cell Voltage (3.2V) × Cell Capacity (Ah) × 16 cells. The kit includes a matched 16S Smart BMS with active balancing, all necessary busbars, hardware, and structural components for safe integration. Designed for future parallel expansion capability.

Next Steps: Define your energy requirements and we'll provide the complete compatible solution - from Grade-A cells to intelligent BMS - ensuring reliable, high-performance battery pack assembly.

Our kit features an advanced Battery Management System with 2A Active Balancing - the core technology that ensures superior performance and extended lifespan for your battery pack.

Passive Balancing (Standard Method):

• Drains excess energy from highest-voltage cells as waste heat
• Wastes battery capacity and generates unnecessary heat
• Only functions during charging phase with slow performance

Our 2A Active Balancing (Superior Technology):

• Intelligently redistributes energy from stronger to weaker cells
• 2A rating enables robust energy transfer at 2 Amps
• Zero energy waste - preserves full battery capacity
• Always active during charge, discharge, and rest periods
• Rapid correction of voltage differences for optimal performance
• Enhanced safety and extended battery pack lifespan

Investment Value: Choosing active balancing ensures maximum usable capacity, reliable long-term performance through thousands of cycles, and superior pack management for your energy storage system.
