Genuine BMW i3 High-Voltage Battery: Bulk Supply – How a European EV Network Secured 200+ Units at OEM Quality, Half the Dealer Price
“EuroEV Solutions manages service centers across five countries. When their BMW i3 customer base hit 1,200 vehicles, battery failures became a crisis—not just a repair. Dealers quoted €12,500–€15,000 per pack with 8-week lead times. Used packs failed within a year. Then they partnered with CNS BATTERY for bulk supply of genuine-grade high-voltage batteries: brand-new 45kWh and 62kWh packs with CATL cells, full OEM compatibility, and a 2-year warranty—delivered at €6,400/unit for orders over 50. They pre-ordered 200 units in Q1 2025. By Q4, 97% were installed, with zero warranty claims. Their service director now says: ‘We didn’t just solve a parts problem—we future-proofed our entire i3 service offering.’”
If you’re scaling an EV fleet, operating a multi-shop chain, or supplying high-voltage components at volume, you’ve likely hit this wall:
- OEM batteries are financially unsustainable for aging i3s
- “Aftermarket” packs often mean recycled cells, no real validation, and short lifespans
- And most bulk suppliers can’t guarantee consistent quality, true plug-and-play function, or long-term support
But here’s what industry leaders now rely on—and CNS BATTERY delivers at scale:
**Genuine-grade BMW i3 high-voltage batteries that meet or exceed original specifications—built with brand-new CATL NMC cells, validated for seamless BMS communication, and backed by a 2-year / 80,000 km warranty—all available through a dedicated bulk supply program with tiered pricing, priority production, and white-glove logistics. These aren’t “compatible” knockoffs; they’re engineered to perform like factory units, down to the CAN signal handshake. For organizations managing dozens or hundreds of i3s, this means predictable costs, minimal downtime, and maximum vehicle uptime. In 2026, bulk supply isn’t about cutting corners—it’s about securing reliability at scale.
This guide shows how professional buyers are locking in long-term access to high-integrity BMW i3 batteries—without dealer markups.
What “Genuine-Grade” Really Means (And Why It Matters at Scale)
| Feature | OEM Dealer Pack | Typical Aftermarket | CNS Genuine-Grade Pack |
|---|---|---|---|
| Cell Origin | New, BMW-approved | Mixed/used/recycled | New CATL NMC (Tier-1) |
| BMS Compatibility | Full | Partial/unstable | Full CAN integration |
| Warranty | 1 year / 50k km | 6–12 months (limited) | 2 years / 80k km |
| Installation | Plug-and-play | May require coding/adapters | True plug-and-play |
| Bulk Pricing (45kWh) | $14,000+ | $5,000–$7,000 | $6,200–$7,100 |
💡 Key insight: Total cost of ownership is lowest with genuine-grade packs—not because they’re cheapest upfront, but because they last, integrate smoothly, and avoid comebacks.
