BMW i3 Battery Replacement: Save 50%+ on High-Performance Upgrades
Why Is Your BMW i3 Battery Losing Range?
Have you noticed your BMW i3’s range dropping significantly after just a few years? That 180km range you once enjoyed now barely makes it to 120km? You’re not alone. Many BMW i3 owners face this frustrating reality as their original battery degrades, forcing them to choose between expensive dealer replacements (often $12,000+) or a costly new car purchase. But what if you could extend your BMW i3’s range by up to 60% for less than half the price of an OEM replacement?
The Real Cost of BMW i3 Battery Degradation
Let’s face it: BMW i3 batteries don’t last forever. After 5-8 years, most owners experience a noticeable drop in range, especially when using climate control or driving in extreme temperatures. The typical dealer solution? A brand-new battery at 80-100% of the original vehicle’s price. But here’s the catch – most dealers use refurbished or recycled cells that fail within months, not years.
Why CNS Battery’s BMW i3 Replacement Modules Are the Smart Choice
Premium CATL Cells, Not Refurbished Batteries
CNS Battery uses brand new CATL ternary lithium cells – the same high-quality cells used by major EV manufacturers. Unlike competitors who use recycled or degraded cells, our battery modules deliver:
- Longer lifespan (well beyond OEM specifications)
- Consistent performance (no sudden drops in range)
- True 45kWh, 50kWh, or 62kWh capacity (not inflated claims)
Simple Installation, No Special Tools Required
Forget the complex, time-consuming installations that require dealership expertise. Our BMW i3 battery modules are designed for straightforward replacement:
- Connect just 6 power lines and 1 signal line (no special tools needed)
- Plug-and-play compatibility with your BMW i3’s BMS system
- Complete battery pack (no need to worry about individual module integration)
2-Year/80,000km Warranty That Actually Covers You
Most aftermarket batteries offer minimal warranty terms. We provide a full 2-year or 80,000km warranty (whichever comes first) on all our BMW i3 battery modules. This means:
- Your battery will maintain at least 75% of its original capacity
- No hidden exclusions or fine print
- Dedicated technical support available throughout the warranty period

Why BMW i3 Owners Are Switching to CNS
“Replacing my 2017 BMW i3 battery with CNS was the best decision I’ve made for my electric vehicle. The range increased from 180km to 290km, and the installation was surprisingly simple. The customer service even provided remote video guidance when I had a minor wiring question. At half the price of the dealership, this was a no-brainer.” – Lisa K., Berlin, Germany
