Wholesale BMW i3 Battery Cells: Bulk Discounts – How Certified Pack Builders Are Sourcing Genuine CATL NMC Prismatic Cells at Factory Rates (With Full Traceability & Safety Certification)

“An EV battery assembler in the Netherlands spent months searching for authentic, new BMW i3-compatible cells—not recycled, not re-wrapped, not ‘grade B’ rejects.

He found dozens of ‘wholesale cell’ suppliers online, but most offered mystery-brand pouch cells, no batch traceability, or inflated cycle-life claims. One shipment arrived with mismatched internal resistance—causing thermal imbalance during testing.
Then he contacted CNS BATTERY—the only global supplier offering Wholesale BMW i3 Battery Cells: Bulk Discounts on brand-new, OEM-spec CATL NMC prismatic cells, complete with cell-level QR codes, UN38.3 certification, and factory test reports.
His first order? 500 cells. All matched within ±1% capacity, passed 300-cycle validation, and formed the core of 20 rebuilt i3 packs that now power municipal fleets in Rotterdam.
Now, he reorders quarterly—and pays 22% less per cell than his initial prototype batch.”

If you’re building, repairing, or upgrading BMW i3 battery packs at scale, you face a critical bottleneck:

• Used or pulled cells from crashed vehicles carry hidden degradation and safety risks
• Generic ‘EV-grade’ cells often lack the voltage profile, impedance, or thermal behavior of genuine i3 units
• No bulk discounts below 1,000+ units, locking out small-to-mid assemblers
• Zero documentation for safety compliance, insurance, or resale

The truth is, the performance and safety of any i3 pack start at the cell level. And while many claim to sell “OEM-quality” cells, few can prove origin, consistency, or certification.

CNS BATTERY cuts through the noise. As a direct partner with CATL (Contemporary Amperex Technology Co. Limited) and a specialist in BMW i3 systems since 2018, we offer wholesale access to the exact NMC prismatic cells used in our own certified packs—now available loose for qualified builders, with structured bulk discounts, full traceability, and safety documentation included.

Here’s what sets CNS apart in the cell wholesale market:

• ✅ Genuine new CATL NMC prismatic cells—same chemistry and format used in BMW i3 production
• ✅ Factory-direct pricing: Save 15% at 300 cells, 20% at 600+, up to 25% at 1,200+ units
• ✅ Full batch traceability: Each cell stamped with QR code linking to capacity, IR, and production date
• ✅ Pre-screened & graded: Only Grade A cells shipped—capacity variance <1%, internal resistance matched
• ✅ Certified for transport & integration: Includes UN38.3, MSDS, CE, and IEC 62133 test summaries

Unlike grey-market resellers, CNS doesn’t broker third-party inventory—we allocate cells from our dedicated CATL production line, ensuring authenticity from cathode to crate.
