Core Manufacturing Capabilities
Our assembly infrastructure accommodates complex mechanical constraints, high-rate continuous discharge requirements, and harsh operating environments.
Chemistry & Formats
LiFePO4 (LFP), NMC, and Sodium-ion (Na-ion) platforms utilizing prismatic, cylindrical (21700/18650), and pouch formats selected according to mechanical envelopes and continuous discharge demands.
Voltage & Capacity
Modular architecture scalable from 12V instrumentation batteries up to 96V traction, commercial marine, and stationary energy storage systems.
BMS & Telemetry
Integrated hardware matching CANbus (CANopen, J1939) and RS485 communication protocols. Bluetooth State-of-Charge monitoring standard; optional 4G/IoT cloud diagnostic integration.
Enclosures & Ingress Ratings
Flame-retardant ABS/PC enclosures, extruded anodized aluminum, and 316 stainless steel casings. Complete epoxy structural potting available for IP67/IP68 submersible environments.
Critical Engineering Audits Before Production
- Pack-Level vs. Cell-Level Certification: Cell certification (UL 1642) does not certify complete battery packs. We provide full-pack test reports (UN 38.3, IEC 62619, CE) matching the finalized mechanical and electrical architecture.
- Total Enclosure & Potting Mass: System weight calculations must account for internal thermal barriers, busbars, heavy-duty structural casings, and potting resins, which add mass beyond bare cell energy density (Wh/kg).
- Controller Protocol Matching: We map BMS firmware registers to your host inverter or motor controller protocol prior to assembly to eliminate communication and handshake faults during field integration.
Agile Production Volumes
Pilot validation units and serial production batches operate through standardized quality controls, maintaining identical welding and testing tolerances regardless of order scale.
No MOQ
Applicable to engineering validation prototypes and packs utilizing existing mechanical enclosures and standard BMS architectures.
100+ Units
Standard threshold when project specifications require bespoke enclosure tooling, custom wiring harnesses, or customized BMS firmware.
300-500 Units
Recommended volume tier for architectures requiring independent laboratory pack certifications (such as UL 1973 or IEC 62619).
100% End-of-Line Quality Verification
Every production pack undergoes full-cycle capacity verification, continuous discharge load testing, dielectric insulation tests, and automated BMS cutoff verification before packaging.
Automated Aging & Cycling Racks
Automated charge-discharge cycles verify cell balancing consistency and initial capacity retention, archived per serial number.
Continuous Load & Thermal Cutoff Verification
Packs operate against rated continuous and pulse discharge currents to validate thermal dissipation and low-voltage protection thresholds.
Manufacturing Operations FAQ
What are typical production and sample lead times?
Engineering validation samples typically dispatch within 15-20 business days depending on cell inventory. Serial production runs average 30-35 business days from BOM sign-off. Compliance testing and ocean freight transit are scheduled independently.
How is cell quality and consistency maintained across batches?
We procure Grade-A cells directly from certified Tier-1 manufacturers (EVE, REPT, Gotion) with traceable factory batch codes. Cells undergo automated capacity and internal resistance (IR) sorting prior to pack welding.
Are Dangerous Goods (DG) packing and export documentation handled?
Yes. We provide complete Dangerous Goods (DG) packaging certified to UN specifications, issue compliant UN38.3 test summaries, and manage export customs clearance documentation directly with freight carriers.
