At Dongguan Wuxin New Energy Power Technology Co., LTD, we specialize in the custom design and precision assembly of lithium-ion battery packs for a wide range of applications, including electric vehicles, industrial equipment, energy storage systems (ESS), and consumer electronics. We understand that selecting the right battery partner is a critical decision. This FAQ addresses the most common questions we receive from our clients.
1. About Our Capabilities & Services
Q: What types of battery packs do you specialize in?
A: We assemble custom lithium-ion battery packs using various chemistries (LiFePO4, NMC, LCO, etc.) for diverse voltage, capacity, and form-factor requirements. Our expertise spans from low-volume, high-complexity prototypes to high-volume production runs for OEMs.
Q: Do you offer full in-house services from design to production?
A: Yes. We provide end-to-end solutions:
- Design & Engineering: Cell selection, module design, BMS integration, thermal management, and enclosure design.
- Prototyping & Testing: Functional prototypes followed by rigorous testing (electrical, environmental, safety).
- Assembly & Manufacturing: Automated and manual assembly lines in a controlled environment.
- Quality Assurance & Certification Support: Full traceability, and we guide clients through relevant certifications (UL, IEC, UN38.3, CE, etc.).
Q: What is your typical production capacity and lead time?
A: Our capacity is scalable. We support pilot runs from 100 units to full-scale production of tens of thousands of units per month. Lead times vary by project complexity: prototypes in 4-8 weeks, production batches in 8-16 weeks. We provide a detailed timeline after the design freeze.
2.Technical & Design Considerations
Q: Can we provide our own cell supplier, or do you source them?
A: We are flexible. We have established partnerships with top-tier cell manufacturers (like CATL, LG, Samsung, or Murata) and can procure cells on your behalf. We also welcome client-designated suppliers, subject to our quality verification.
Q: How do you ensure Battery Management System (BMS) compatibility and safety?
A: Our engineering team either designs proprietary BMS solutions tailored to your pack or integrates best-in-class third-party BMS units. Every BMS is rigorously programmed and tested for functionalities like cell balancing, overcharge/over-discharge protection, temperature monitoring, and state-of-charge (SOC) accuracy.
3.Quality, Safety & Compliance
Q: What quality control measures do you have in place?
A: Quality is embedded in every step:
- Incoming Inspection: 100% cell screening (voltage, internal resistance).
- In-Process Checks: Automated welding inspection, component placement verification.
- End-of-Line Testing: Full functional test, Hi-Pot (dielectric withstand) test, capacity grading, and cycling.
Q: What is your approach to failure analysis and warranty?
A: We have a detailed root-cause analysis (RCA) process for any field returns. Warranty terms (typically 1 years on workmanship and pack integrity) are specified in our contract, covering defects in materials and assembly.
4.Logistics & Commercial Terms
Q: Do you handle shipping and logistics, especially for international clients?
A: Yes. We have extensive experience preparing all necessary documentation for the safe and legal transport of lithium-ion batteries. We can manage shipping from our factory to your designated port or facility.
Q: What is your typical pricing model?
A: Pricing is project-specific, depending on cell type, pack complexity, order volume, and testing requirements.
Q: Can you sign NDAs and IP agreements?
A: Absolutely. We treat all client information and designs as strictly confidential. We are prepared to sign comprehensive NDAs and agreements that clearly state your ownership of all design IP.
