Factory to Doorstep: We Control Every Step
We are a manufacturer, not a trading company. R&D, production, quality control, and logistics are all in-house at our Guangdong facility. No outsourced sub-assembly, no hidden supply chain.
- In-house, no outsourcing
- BMS hardware + firmware engineering
- PCB design (SolidWorks, ±0.1mm)
- Cell sorting, tabbing, laser spot welding
- Cleanroom BMS assembly (ESD-controlled)
- Formation cycling + 8-hr aging test
- IEC-traceable calibration records

End-to-End Battery Manufacturing
Four integrated functions — all in-house, all under direct quality control. This is what "factory direct" actually means.
R&D / Engineering
From brief to validated prototype in 2–3 weeks.
- In-house PCB design and BMS hardware engineering — no outsourcing
- Custom firmware development for proprietary display protocols (UART, CAN, BLE)
- Enclosure CAD in SolidWorks — toleranced to ±0.1mm, DFM review included
- Sample turnaround: 5–10 working days for standard platforms; custom tooling quoted after review
- NDA signed before any file exchange — your IP stays yours
Manufacturing
300+ team members · Flexible production · Up to 120K daily output.
- Semi-automated cell sorting and tabbing — capacity-binned cells matched ±2%
- Automated laser spot welding with in-line weld resistance measurement per joint
- Cleanroom BMS assembly area — ESD controlled, humidity monitored
- Formation cycling: every cell activated and capacity-verified before module assembly
- ISO 9001 certified production management system — full work order traceability
Quality Control
100% cell screening · X-ray inspection · 8-hour aging test.
- 100% incoming cell impedance and capacity screening — out-of-spec lots quarantined
- X-ray inspection of module connections — every production batch, not just spot-check
- 8-hour elevated-temperature aging test on finished packs — capacity must be ±3% spec
- Calibrated test equipment per IEC standards — traceable calibration records maintained
- Full test report per shipment: cell lot numbers, BMS firmware version, capacity data
Logistics
UN38.3 · MSDS · Air-freight compliant · 30+ countries.
- Incoterms: FOB Shenzhen, EXW Dongguan, DDP available for EU/US on request
- IATA PI 965/966 documentation for air freight — standard for all orders
- Sea LCL/FCL coordination to EU (Rotterdam, Hamburg) and US (LA, NY) ports
- MSDS/SDS in EN/DE/FR/ZH — customs documentation pre-prepared per destination
- White-label packaging, neutral outer carton, or custom branded — your choice
Custom Battery Management, Not Off-the-Shelf
Our BMS hardware and firmware are designed by our internal R&D team. This means we can match your exact display protocol, configure cutoff voltages to your motor controller's spec, and implement proprietary communication protocols under NDA.
Off-the-shelf BMS vendors can't do this. We can.

Tier-1 Cells, Authorized Channels Only
Samsung SDI, LG Energy Solution, Panasonic, and CATL are our primary Tier-1 cell lines, sourced directly from authorized distributors with lot traceability documentation. EVE and Lishen are available for cost-optimized programs when buyers specify them in the RFQ. We do not use spot-market or grey-channel cells. Every batch includes COA, test data, and lot traceability linked to your production serial numbers.
