Chalong Fly Lithium Battery R&D Engineering Team in China

Research and Development

Innovating the Future of Lithium Energy Storage

Engineering Your Energy Future

At Chalong Fly, we are not just a manufacturer; we are your technical partner in lithium technology. Unlike simple pack assemblers, we leverage a vertical industry chain—from cell chemistry to smart BMS integration—to ensure quality, cost-efficiency, and customization speed.

1. Smart BMS Development

Our in-house electronic engineers design proprietary Battery Management Systems (BMS) ensuring your battery "talks" perfectly with your inverter, vehicle, or equipment.

  • Hardware & Software integration
  • Communication protocols: CANbus, RS485, RS232, Bluetooth

2. Structural & Thermal Design

Safety starts with structure. Our mechanical engineers utilize 3D simulation to design casings for harsh environments.

  • Vibration & shock resistant structures
  • Extreme temperature thermal management
  • IP65/IP67 waterproof ratings

3. State-of-the-Art Testing Lab

Safety is our bottom line. Every prototype undergoes rigorous testing in our CNAS-standard laboratory before mass production. We don't guess; we verify.

  • Safety Testing: Nail penetration, Crush test, Over-charge/Over-discharge protection.
  • Environmental Testing: High/Low temperature cycling (-20°C to 60°C).
  • Physical Testing: Vibration simulation (critical for AGV/forklift) and Drop tests.

R&D and Customization FAQ

Can you customize the BMS communication protocol to match our specific inverter or vehicle?

Yes, absolutely. Unlike assemblers who use off-the-shelf standard BMS, Chalong Fly has an in-house software engineering team. We can customize the BMS protocols (CANbus, RS485, RS232, UART) to ensure seamless communication with your specific brand of inverter, electric vehicle controller, or AGV system.

How long does it take to get a custom battery prototype?

We pride ourselves on speed. Once we confirm your requirements (Voltage, Capacity, Dimension, Current), our R&D team provides a 3D technical drawing within 48 hours. For most custom battery packs, we can finish the sample production and testing within 10-15 working days.

What safety tests are performed on the battery packs before shipment?

Safety is our priority. Every new design undergoes a full suite of tests in our CNAS-standard laboratory, including nail penetration, crush testing, drop testing, and thermal shock cycling (-20°C to 60°C). We ensure the battery remains stable even under extreme abuse conditions before it goes into mass production.

What type of cells do you use for your custom battery packs?

We primarily use Automotive-grade LiFePO₄ (Lithium Iron Phosphate) cells. We select cells with high consistency in internal resistance and voltage to ensure the battery pack has a long cycle life (typically >3000 cycles at 80% DOD) and superior safety compared to ternary lithium or lead-acid batteries.

Do you support low-volume customization for new R&D projects?

Yes, we support our partners from the prototype stage to mass production. We understand that every big project starts small. We offer flexible MOQ (Minimum Order Quantity) for the initial R&D and pilot run phases to help you validate your market or device.
