OEM/ODM Collaboration Process

TURSAN follows a structured six‑phase development path – from requirement analysis to mass production – with clear deliverables and timelines at each stage.

Phase 1
Requirement Analysis

Work with the customer to define target market, application scenario, voltage/capacity/power needs, certification requirements, packaging, and budget.

Phase 2
Technical Proposal

Submit a written proposal covering battery system design, BMS solution, inverter matching, structural concept, and a complete bill of materials.

Phase 3
Prototype Development

Produce samples for functional testing, performance validation, and customer evaluation.

Phase 4
Safety & Reliability Testing

Conduct comprehensive electrical, thermal, ageing, charge/discharge, and BMS tests.

Phase 5
Certification & Compliance

Assist in obtaining product certifications required for the target market, with pre‑integration of international standards such as UN38.3, UL, CE, FCC, and IEC.

Phase 6
Mass Production & Delivery

Move into volume production, leveraging 10+ automated production lines and a full MES traceability system to ensure consistent quality across every unit.

Real‑World Case: A Local Best‑Seller in 90 Days

A distributor in Southeast Asia needed a compact wall‑mounted backup power supply for apartments with limited space. By adjusting the casing dimensions, adding a wall‑mount bracket, and pre‑loading the customer’s preferred inverter settings, TURSAN helped them launch a local best‑seller in under 90 days.

 

This is not an exception – TURSAN has served customers in over 60 countries across portable power, residential storage, and mobile EV charging markets.

Two Manufacturing Bases to Support Your Customization Needs

TURSAN operates two specialized manufacturing facilities in China

Dongguan Base
Solar battery manufacturer

Focuses on residential and commercial energy solutions, producing home batteries, solar batteries, wall‑mounted batteries, and off‑grid/on‑grid inverters. The base employs 200+ staff, including 30+ R&D engineers dedicated to residential storage, and is equipped with automated battery PACK assembly lines.

Shaoguan Base

Specializes in mobile EV charging, portable power stations, SMT assembly, and injection molding.

Together, the two bases cover over 20,000 m² of production space, with 10+ automated lines, an annual capacity of 2 GWh, and more than 500 skilled employees. Every product is fully traceable through the MES manufacturing execution system.

Quality Assurance at Every Step

TURSAN implements a rigorous quality control system that covers the entire production chain:

  • Cell sorting & grading: Each batch of cells is graded by capacity, internal resistance, and voltage curves – only perfectly matched cells enter the battery pack
  • Automatic laser welding: High‑precision laser welding eliminates cold‑joint risks, with each weld inspected by vision systems
  • Module assembly & BMS integration: Torque‑controlled fastening, automatic glue dispensing, BMS connection, and firmware flashing
  • Ageing & burn‑in testing: 100% of finished products undergo burn‑in testing under load, with real‑time monitoring of temperature, voltage, and current
  • Final outgoing inspection: Capacity verification, BMS communication testing, visual inspection, and label confirmation
  • Temperature‑controlled warehousing & shipping: Export‑grade packaging and transport compliant with UN3480 DGR regulations
