Every project begins with a thorough discussion. Our technical experts work closely with you to analyze key parameters including power profiles, operating environments (temperature, vibration, space constraints), expected cycle life, and target market certifications. Leveraging over a decade of industry experience, we quickly identify critical factors to avoid late-stage redesigns, ensuring that our design is built on the right foundation from the very start.

We go beyond cell arrangement, focusing on overall pack reliability under real working conditions. Our design process emphasizes:

• Mechanical Support: Impact and vibration-resistant structures suitable for heavy-duty tool applications.

• Thermal Management: Optimized heat dissipation paths to prevent hotspots and extend cell cycle life.

• Safety Features: Built-in multiple protection circuits (overcharge, over-discharge, short circuit, temperature) combined with V0-grade flame-retardant enclosures to minimize risks.
  We balance performance with manufacturability, ensuring consistency from prototype to mass production.

The Battery Management System is at the heart of safety and performance. Our self-developed BMS features:

• Comprehensive Protection: Millisecond-level response to overcurrent, overvoltage, undervoltage, short circuits, and abnormal temperatures.

• Active Balancing: Enhances cell consistency and maximizes total pack capacity utilization.

• State Monitoring: Provides data on State of Charge (SOC), State of Health (SOH), etc., for smart device interaction.
  Our BMS solutions, validated across hundreds of projects, adapt to various chemistries (Li-ion, LiFePO4, etc.), ensuring stable and reliable operation under demanding conditions.

Charging strategy directly impacts battery lifespan and user experience. We design dedicated chargers based on pack capacity, internal resistance, and charge acceptance to achieve:

• Optimized Charging Profile: Balances charging speed with temperature rise to minimize stress and degradation.

• Intelligent Control: Real-time monitoring of voltage and temperature with dynamic current adjustment.

• Safety Synergy: Communication with the BMS for dual-layer protection between charger and battery.
  Our chargers are designed not only to be compatible with your battery but also to enhance your brand's overall reliability in the eyes of end users.

We understand that certification is a critical gateway to international markets. We provide full-process support from performance testing to documentation, assisting you in obtaining:

• Safety Certifications: CE, UL, KC, PSE, etc.

• Environmental Compliance: RoHS, REACH.

• Transportation Safety: UN38.3 and MSDS (Material Safety Data Sheet), etc.
  Our testing protocol covers dozens of stages including cell grading, protection board inspection, charge/discharge cycling, and high/low temperature aging tests, ensuring every batch meets target market requirements and mitigating trade risks.

Leveraging our strategically located warehouses and established logistics partnerships, we offer flexible delivery solutions:

• Regional Fulfillment: Shortens lead times and reduces your inventory pressure.

• Safe Packaging: Compliant with hazardous material transport regulations for safe sea and air freight.

• Real-Time Tracking: Full shipment visibility to help you coordinate production plans.
  Whether for samples or bulk orders, we are committed to delivering high-quality products on time and at a lower total cost.

We offer a standard 13-month warranty with flexible replacement or compensation policies based on shipping methods (air/sea). Beyond that, our after-sales team is always available for:

• Technical Consultation: Rapid response to operational inquiries.

• Repair & Replacement: Timely handling of non-artificial damage.

• Maintenance Guidelines: Helping your end-users maximize battery lifespan, thereby enhancing your brand reputation.
  We believe reliable after-sales support is a cornerstone for your business growth.

1. Initial Consultation: We begin by understanding your specific power requirements, application needs, and any special considerations such as size constraints or environmental factors.
2. Design Proposal: Based on the consultation, we provide a detailed design proposal outlining the optimal arrangement of battery cells, physical enclosure design, connectors, wiring, and safety features.
3. 3D Sample Confirmation: After rigorous testing for performance and safety, we ship out a 3D sample and await your confirmation.
4. Production Initiation: Upon receipt of a 30% deposit, we initiate sample production.
5. Sample Confirmation: Before final production, we provide samples for your confirmation, allowing you to review and validate the design and functionality of the custom battery pack.
6. Production and Assembly: Upon successful sample confirmation, we proceed with mass production and assembly of the custom battery packs, maintaining strict quality control throughout the process.
7. Balance Payment and Delivery: After production completion, we request the balance payment. Upon receipt, we arrange for the delivery of your custom battery packs, ensuring timely and secure shipment.
8. Ongoing Support: We provide ongoing support, including troubleshooting assistance, repair or replacement services for faulty packs, and offering maintenance guidelines to maximize the lifespan and performance of the battery packs.

Our comprehensive custom battery pack development process ensures that you receive a high-quality, reliable, and tailored solution that meets your specific power needs and application requirements.

1. Our team confirms the necessary files and order details.
2. Manufacture SMT stencil (if needed).
3. Program our machines from the BOM and Centroid file, before the materials arrive. Discrepancies found in the files will be addressed.
4. After all the materials are received, our team performs a kit audit of the materials. Discrepancies or additional questions will be addressed. Before the assembly lead time begins we must have all questions answered.
5. If all materials are in before 12pm PST, the assembly lead time starts the next business day. Materials received after 12pm PST will be considered received on the next business day. The reason for this is to allow proper time for the materials to go through the kit audit process.
6. The SMT components are assembled first with our automated equipment. The first board goes through extensive QA to assure part placement and polarity are correct. The boards are then inspected (visually and with an AOI machine) as they come off the reflow oven.
7. BGA components are X-rayed to verify placement accuracy and to detect any solder bridges.
8. After SMT the boards are washed when applicable.
9. Thru-hole components are inserted and soldered by hand or with a selective soldering machine depending on the quantity and board design.
10. After thru-hole boards are washed again when applicable.
11. A final quality inspection is performed.
12. The finished PC board assemblies and all extra materials are prepped for packaging.
