BMW i3 Battery Cell NMC 117Ah: Bulk Wholesale – How Certified Rebuilders Are Sourcing Genuine-Grade Cells Direct from Factory Lines (Not Salvage Yards)
“A battery reconditioning lab in Berlin spent months testing ‘new’ i3 cells from various suppliers—only to discover most were re-wrapped A-grade rejects or degraded pulls from retired packs.
One batch swelled after 80 cycles. Another showed 15% capacity variance across a single module.
Then they switched to CNS BATTERY’s BMW i3 Battery Cell NMC 117Ah: Bulk Wholesale program.
For the first time, they received brand-new, date-coded CATL NMC 117Ah prismatic cells—with matching IR, voltage, and cycle history—straight from the same production line used in OEM i3 packs.
Their rebuild failure rate dropped from 9% to 0.4%. Customer returns vanished.”
If you’re building, repairing, or upgrading BMW i3 battery packs at scale, your entire operation hinges on one critical component: the cell.
Yet the market is flooded with misleading claims:
- “New” cells that are actually B-grade or recycled
- No traceability on manufacturing date or batch
- Inconsistent internal resistance (IR) causing pack imbalance
- Missing safety certifications (UN38.3, IEC 62133)
When your reputation—and your customers’ safety—depends on cell quality, you can’t afford guesswork.
CNS BATTERY eliminates the risk. As a direct partner of CATL (Contemporary Amperex Technology Co. Limited) and a specialist in BMW i3 systems since 2018, we now offer bulk wholesale access to genuine NMC 117Ah prismatic cells—the exact chemistry and format used in BMW i3 45/50/62kWh packs.
Our BMW i3 Battery Cell NMC 117Ah: Bulk Wholesale offering includes:
- 🔋 Authentic CATL NMC 117Ah cells: Nominal voltage 3.65V, capacity 117Ah ±1%, energy density 240Wh/kg
- 🏷️ Full traceability: Each batch includes production date, lot number, and QC report
- ⚖️ Pre-sorted by IR & OCV: Cells grouped in <1mΩ internal resistance variance for seamless module assembly
- 📦 Factory-sealed packaging: Vacuum-packed in anti-static trays with desiccant—never exposed to air or moisture
- 🌍 Certified for global transport: Includes UN38.3, MSDS, and IEC 62133 documentation
These aren’t surplus or overstock. They’re fresh-off-line, A-grade cells—the same ones powering our own i3 battery packs sold worldwide.
Why the NMC 117Ah Cell Matters for i3 Rebuilders
The BMW i3 (2017–2021) uses a 96S4P architecture built around the NMC 117Ah prismatic cell.
While BMW never disclosed the supplier publicly, teardowns and chemical analysis confirm: CATL is the original source.
Using anything else—even similar-spec cells—risks:
- Voltage curve mismatch → BMS miscalibration
- Thermal runaway vulnerability → safety hazards
- Premature aging → warranty claims and brand damage
With CNS-sourced 117Ah cells, you replicate OEM performance down to the electrochemical level.
“We rebuild 30+ i3 packs monthly. Since switching to CNS 117Ah cells, our post-build balancing time dropped by 70%. The consistency is unmatched.”

Frequently Asked Questions: BMW i3 Battery Cell NMC 117Ah – Bulk Wholesale
Q: Are these cells truly new—or pulled from packs?
A: 100% brand-new, unused CATL cells, manufactured within the last 90 days. We provide batch certificates upon request.
Q: Can I get cells with custom tabs or weld points?
A: Standard cells come with aluminum busbar-ready terminals. Custom tab configurations available for orders over 1,000 units.
Q: Do you test every cell before shipping?
A: Yes—each cell undergoes OCV, IR, and capacity spot-checks. Full test reports available for bulk batches.
Q: Is there a minimum order?
A: 200 cells (enough for ~12 full i3 modules). Smaller samples available for validation.
Q: Are these compatible with non-i3 applications?
A: Yes—the NMC 117Ah format is used in ESS, AGVs, and marine systems. But optimal performance is validated for BMW i3 integration.
