BMW i3 94Ah Battery Module: Wholesale Supply – The Missing Link That Lets You Build 45kWh+ Packs Without Hunting Junkyard Cores
“A battery rebuilder in Toronto spent three weeks sourcing ‘good’ 94Ah modules from salvage yards across Ontario. He paid $320 each, tested 28 units, and only 16 passed basic voltage checks. After assembling two 45kWh packs, one failed during validation due to a hidden cell imbalance. Frustrated, he switched to CNS brand-new BMW i3 94Ah battery modules. For $395 each—wholesale—he got fully tested, balanced, and warranty-backed modules that dropped straight into his builds. Both packs passed on the first try. His verdict: ‘Why waste time gambling on used when new is this close in price—and infinitely more reliable?’”
If you’re rebuilding or upgrading BMW i3 battery packs—especially targeting 45kWh (120Ah) or custom high-capacity systems—you know the bottleneck: finding reliable 94Ah modules.
- Salvage-yard modules are inconsistent: hidden damage, unknown history, mismatched SOH
- Refurbished units often reuse degraded cells: short lifespan, high failure risk
- Lead times stretch for weeks: delaying jobs and frustrating customers
Most assume “new modules aren’t available.” But what if you could source factory-fresh, OEM-spec 94Ah modules—built with brand-new CATL cells, pre-balanced, and ready for integration—at a price that makes economic sense?
Now, professional rebuilders and EV specialists are doing exactly that—and CNS BATTERY, as a direct manufacturer deeply embedded in the BMW i3 ecosystem, offers wholesale supply of genuine new BMW i3 94Ah battery modules, engineered to match BMW’s original 2019–2021 pack architecture.
Clarification: The “94Ah” designation refers to BMW’s internal naming for the higher-density module used in 45kWh (120-cell) i3 packs (2019–2021). Each module contains 12 series-connected NMC cells at ~94 ampere-hours nominal—critical for achieving 40+ kWh usable capacity. CNS modules replicate this design exactly, using new CATL cells, OEM-equivalent busbars, and matched internal resistance—so they integrate seamlessly into full-pack assemblies. For shops tired of sorting through unreliable cores, this isn’t just convenience—it’s a production game-changer. In 2026, building high-capacity i3 packs shouldn’t depend on luck.
This guide reveals how access to new 94Ah modules is transforming rebuild speed, quality, and profitability—and how you can secure your supply today.
Why Used 94Ah Modules Are a Hidden Liability
| Risk Factor | Used/Refurbished Module | CNS New 94Ah Module |
|---|---|---|
| Cell Origin | Unknown; often cycled >1,000 times | Brand-new CATL NMC cells |
| Internal Resistance | Variable (80–150mΩ); causes imbalance | Matched ≤60mΩ ±3mΩ |
| Cycle History | Untraceable; may be near end-of-life | Zero cycles; full lifespan ahead |
| Warranty | None or 30–90 days | 2-year / 80,000 km coverage |
| Lead Time | Weeks of hunting + testing | Ships in 3–5 business days |
⚠️ Reality check: A single weak 94Ah module can drag down an entire 45kWh pack—triggering premature shutdowns, reduced regen, or BMS faults. Consistency isn’t optional; it’s foundational.

Frequently Asked Questions: BMW i3 94Ah Battery Module – Wholesale Supply
Q: Are these compatible with 2017–2018 i3 packs?
A: Yes—but note: 2017–2018 i3s use 60Ah modules (lower density). 94Ah modules are designed for 2019–2021 i3 120Ah (45kWh) systems. However, they can be used in custom high-capacity retrofits with proper BMS adaptation.
Q: Do I need special tools to install them?
A: Standard EV safety gear and torque wrenches suffice. No proprietary equipment needed.
Q: Can I mix CNS modules with OEM ones?
A: Technically yes—but not recommended. For optimal balance, use all new or all OEM. CNS modules are batch-matched for uniformity.
Q: What’s the expected cycle life?
A: 1,500+ cycles to 80% State of Health under normal conditions.
Q: Is technical support available for pack assembly?
A: Yes—CNS provides free remote guidance on module arrangement, wiring, and BMS integration for wholesale clients.
