OEM BMW i3 Battery Pack: Maximize Your Range Without Paying BMW Prices (2026)
The BMW i3 Battery Dilemma: Why You’re Paying 3x More Than You Should
Imagine driving your beloved BMW i3, only to discover your range has plummeted from 180km to barely 80km. You check with the dealer, and they quote you $12,000 for a “new” battery. That’s nearly half the value of your car! But what if you could extend your range by 60% while saving over $6,000? This isn’t a dream—it’s the reality for thousands of BMW i3 owners who’ve switched to CNS BATTERY’s OEM-compatible solutions.
Why BMW i3 Owners Are Switching to CNS BATTERY
When your BMW i3 battery degrades, most owners face a brutal choice: pay the dealer’s premium price or risk unreliable third-party options. CNS BATTERY solves this dilemma with a true OEM-compatible battery that matches factory specifications while delivering superior value.
The CNS Advantage: Quality Meets Affordability
Unlike dealers who charge top dollar for batteries with aging cells, CNS BATTERY uses brand-new CATL lithium cells—the same cells used by major EV manufacturers. This isn’t a refurbished battery; it’s a fresh, high-performance solution that:
- Delivers 45kWh, 50kWh, or 62kWh capacity options
- Uses CATL brand new ternary lithium cells (China’s largest battery manufacturer)
- Comes with a 2-year/80,000km warranty (longer than most OEM warranties)
- Provides real-world range improvements (290km+ instead of 180km)
As one satisfied BMW i3 owner in Berlin shared: “After the original battery degraded, the 4S dealership quoted €12,000. CNS delivered a brand-new CATL battery that performed like the factory unit, and I saved over 50%.”

Real Range Improvements: From 180km to 290km+ (Without Compromising Performance)
Don’t just take our word for it—here’s what actual BMW i3 owners report after switching to CNS BATTERY:
“After replacing my 2017 BMW i3’s degraded battery with CNS’s 45kWh solution, the full charge range increased from 180km to 290km. I only need to charge it once a week for daily commuting, and the range remains consistent even in winter conditions. The installation was straightforward with the detailed video guide, and the remote technical support was exceptional when I had a minor wiring question.” – Lisa K., Berlin, Germany
Another owner added: “The sea shipping took 6 weeks, but the packaging was a fumigation-free wooden crate, so the battery arrived undamaged. The lifetime technical support is amazing—I even got a customized guide for winter charging optimization last month.”
Why DIY Installation is Simpler Than You Think
Many BMW i3 owners worry about installation complexity. The good news? CNS BATTERY makes it remarkably simple:
- Full battery pack: Just plug and play—no modifications needed
- Battery modules: Connect 6 power lines and 1 signal line (all color-coded)
- Comprehensive support: Step-by-step installation videos and remote video guidance
As one owner in London shared: “I was worried about the installation, but following the video tutorial took me only 1 hour to replace the old battery and another hour to install the new one. The wiring was straightforward, and when I had a programming issue, customer service resolved it in 5 minutes via remote video.”
The Cost Savings That Add Up: $6,000+ in Your Pocket
Let’s break down the real savings:
| Option | Price | Range | Warranty |
|---|---|---|---|
| BMW Dealership | $12,000 | 180km | 2 years/60,000km |
| CNS BATTERY | $6,500 | 290km | 2 years/80,000km |
That’s $5,500 in immediate savings plus 20,000km more warranty coverage—all while getting better performance. For a vehicle that’s already depreciated, this is the smartest investment you can make.
