Technical Advantages & Manufacturing Excellence

What sets our solar energy lithium battery packs apart is our specialized manufacturing process designed for harsh outdoor environments:

Vacuum-Sealed Protection: Every pack is vacuum-packed with environmentally friendly, heat-insulating PVC.¹ This process prevents air gaps between cells, reducing heat buildup and enhancing the battery’s safety and lifespan.
Advanced Waterproofing: During the molding stage, we apply specialized waterproof glue to all gaps. This provides an extra layer of protection against rain and humidity, preventing water ingress and internal short circuits—essential for outdoor solar garden lights.
Grade A 18650 Cells: We only use high-quality 18650 cells to ensure a stable 3.7V output and a full 4000mAh capacity for long-lasting performance.
Integrated Safety BMS: The built-in protection board monitors the pack 24/7 to prevent overcharging, over-discharging, and over-current issues.
