VOLTRIX is the export brand of Xingchuang Yilai New Energy Technology (INTERSTELLA) — the IATF16949-certified factory that designs and assembles every pack on this site. These are our own lines and test racks, photographed at the Xianyang plant in Shaanxi. No renders, no stock photography.
Automotive-grade quality system, alongside ISO 9001, ISO 14001 and ISO 45001.
Dedicated assembly lines for cylindrical, prismatic and pouch cells.
Cell grading, laser welding and charge/discharge testing are built into the line.
Our showroom and workshop buildings at the Xianyang site.
Three dedicated assembly lines, one for each cell format we build.
From graded cells to a finished, tested pack — the stations an order passes through.
Automated laser welding of busbars and tabs, with process monitoring on each joint.
Packs are charged, discharged and aged on these racks before shipment. Test records are kept for each batch and shared with buyers on request.
A dedicated engineering team handles custom OEM / ODM builds — cell selection, mechanical design, BMS configuration and validation for your application.
We will walk the line with you live on WhatsApp — cell grading, laser welding, ageing racks and end-of-line testing. No pre-recorded loop.
You may appoint SGS, Intertek or your own agent to inspect before shipment; we provide the packing list and test records they ask for.
IATF16949 certificate number, UN38.3 and CE (EMC) report numbers can be checked with the issuing bodies. Copies are sent on request.
Tell us your application and target capacity — we will quote and set up a live tour of the plant.
