Product List
Engineering & Cell Selection
Jetray carefully selects automotive-grade 18650, 21700, and prismatic cells, performing strict matching of voltage, capacity, and internal resistance. Our engineering team uses advanced 3D modeling to design the pack layout and BMS configuration, ensuring optimal performance and safety.
Professional Assembly & BMS Integration
In Jetray’s ISO-certified workshop, cells are spot-welded or laser-welded and integrated with smart Battery Management Systems (BMS) for protection, balancing, and communication (CAN/RS485). The pack is sealed in durable, IP-rated enclosures to meet demanding environments.
Quality Testing & Global Compliance
Each pack undergoes Jetray’s rigorous testing process—charge/discharge cycling, thermal stress, vibration, and drop tests—to guarantee compliance with CE, UN38.3, and international standards before secure packaging and worldwide delivery.
