Your cells. Our architecture.
One serial number
from chemistry to crate.
Robotic cell assembly, ultrasonic weld inspection, and full-stack BMS integration — purpose-built for EV startups, energy-storage integrators, and industrial fleet OEMs.
Five stages. Every tolerance
measured in microns.
Each card is a live comparison between building in-house and running on our line. The numbers count up when you arrive — because data earns the click, not copy.
Cell Sourcing
We qualify cells from CATL, Samsung SDI, and LG ES to your voltage window and cycle-life spec, then incoming-inspect every lot against IEC 62660.
Module Welding
6-axis robotic placement to ±0.05 mm, fiber-laser busbar welding at 2 kW, and 100% inline ultrasonic inspection for weld integrity — every joint logged to serial.
BMS Integration
We integrate and flash your BMS firmware (or our reference design), run cell-balancing validation, CAN/SMBus protocol tests, and thermal runaway simulation per UL 9540A.
Pack Enclosure
Aluminum extrusion or stamped-steel enclosures with phase-change TIM at 4.5 W/m·K, IP67 sealing, and vibration isolation qualified to IEC 62619 shock/vibe profiles.
EOL Testing
Every pack completes a full formation cycle on our Maccor cyclers, passes a 48-point functional test, and ships with a serialized test report traceable to your customer's SN.
97% fewer weld defects.
Across 500 to 50,000 packs annually, our line consistently beats in-house assembly on defect rate, cycle time, cert coverage, and cost-per-kWh — simultaneously.
Every layer.
Every tolerance.
Hover each layer to inspect the spec. What looks like a battery pack is actually five precision manufacturing decisions stacked in 187 mm.
18 certs. Zero
procurement surprises.
Every certification we hold is available as a signed PDF. Procurement leads: download the full cert library before the first conversation.
