Revolutionize Your BMW i3: The Ultimate 45kWh NMC 117Ah Battery Upgrade
Is Your BMW i3 Losing Range at an Alarming Rate?
Imagine driving your beloved BMW i3, only to find yourself stranded with 30 miles left on the battery when you need 100. You’ve noticed the range shrinking month by month, and the thought of paying $12,000 for a factory replacement makes your wallet scream. You’re not alone. Many BMW i3 owners face this exact dilemma, but there’s a smarter, more affordable solution that delivers superior performance without breaking the bank.
Why the BMW i3 Battery Degrades Faster Than Expected
The BMW i3 was designed as a true electric vehicle, not a plug-in hybrid. Its battery system, while innovative for its time, isn’t immune to the natural aging process. After 3-5 years of regular use, most owners experience a significant drop in range—often 20-30%—which can turn daily commutes into stressful planning sessions. Many assume they’ll need to replace the entire vehicle, but this isn’t the case. The real solution lies in a high-quality battery upgrade that matches or exceeds the original factory specifications.
The CNS BATTERY Advantage: 45kWh NMC 117Ah for BMW i3
Unlike generic battery replacements that use recycled or degraded cells, CNS BATTERY delivers a brand-new 45kWh NMC 117Ah battery pack specifically engineered for BMW i3 models. Here’s what sets us apart:
✅ Premium CATL Battery Cells: The Gold Standard
We don’t use recycled or refurbished cells. Our batteries feature brand-new CATL NMC 117Ah lithium-ion cells—the same high-quality cells used by top EV manufacturers. CATL is China’s largest battery producer, renowned for its exceptional safety and performance standards, ensuring your BMW i3 battery operates at peak efficiency.
✅ OEM Compatibility Without the OEM Price Tag
Our battery is 100% OEM-compatible, meaning it fits perfectly into your BMW i3 without any modifications. Unlike many competitors who require costly adapter kits, our battery integrates seamlessly with your vehicle’s BMS (Battery Management System), requiring no programming or additional components.
✅ 50%+ Cost Savings Without Sacrificing Quality
Why pay $12,000 for an original BMW battery when you can get a high-performance 45kWh battery for just $7,800? CNS BATTERY delivers OEM-quality performance at approximately 50% of the original manufacturer’s price—saving you thousands while extending your vehicle’s life.
✅ 2-Year/80,000km Warranty for Peace of Mind
We back our product with a comprehensive 2-year or 80,000km warranty (whichever comes first). This is longer than most competitors’ warranties and significantly more robust than the typical 26-month/60,000km coverage you’d get with cheaper alternatives. Our warranty covers any manufacturing defects, ensuring your investment is protected.
Real Results from Real BMW i3 Owners
“The original battery in my 2017 BMW i3 had degraded to only 180km range. After installing the CNS 45kWh battery, the full charge now provides 290km of range. The installation was straightforward with the detailed video guide, and the customer service provided remote video support within an hour when I had a minor wiring question. The CATL cells are top-quality, and the price was less than half of what the BMW dealership quoted.”
— Lisa K., Berlin, Germany
“I was skeptical about an aftermarket battery, but the CNS 45kWh unit exceeded my expectations. The range increase is significant, and the battery feels like it’s from the factory. The installation took just 2 hours, and the 2-year warranty gives me confidence in the product’s longevity.”
— David L., London, UK
