Upgrade Your BMW i3 with OEM-Compatible Batteries: Save 50%+ on High-Performance 45kWh, 50kWh & 62kWh Battery Packs

Why Is Your BMW i3’s Range Dropping So Fast?

Have you noticed your BMW i3’s battery range shrinking dramatically after just 3-5 years? You’re not alone. Many BMW i3 owners face the painful reality of a degraded battery that can’t even reach the original 150km range. The official BMW replacement costs $12,000+—a price tag that makes most owners consider buying a new car instead of fixing their current one.

The Smart Solution for BMW i3 Owners: OEM-Compatible Battery Replacement

CNS BATTERY has revolutionized the BMW i3 battery replacement market with OEM-compatible battery packs that deliver factory-grade performance at 50%+ lower costs. We’ve helped over 1,500 BMW i3 owners across 25 countries extend their vehicle’s lifespan without breaking the bank.

Why Choose CNS BATTERY for Your BMW i3?

Brand-New CATL Battery Cells
Unlike refurbished batteries that swell and fail within months, we use only brand-new CATL lithium cells—the same quality used by BMW in their factory batteries. This ensures consistent performance and safety.

Perfect Vehicle Compatibility
Our battery packs are engineered specifically for BMW i3 models (2014-2023), with seamless integration that matches the original factory battery’s dimensions, connectors, and BMS programming.

Extended Warranty Protection
Get a 2-year/80,000km warranty—longer than most OEM warranties—covering capacity degradation down to 9 bars from the original 12. This warranty is transferable and covers all battery-related issues.

Cost Savings That Make Sense
Instead of paying $12,000+ for an OEM battery, our 45kWh, 50kWh, and 62kWh packs cost just $5,800-$8,200, saving you up to $6,000 while delivering better range.

The BMW i3 Battery Upgrade Experience: Real Results

“After the original battery degraded, the BMW dealership quoted €12,000 for a replacement. I chose CNS BATTERY’s 45kWh pack instead. The brand-new CATL cells were of the same quality as the original. With remote video guidance from their engineers, I installed it myself in under 2 hours. Now my full charge range has increased from 180km to 290km—perfect for my daily commute. The lifetime technical support is incredible!”
Lisa K., Berlin, Germany

“I was skeptical about aftermarket batteries, but CNS BATTERY’s 50kWh pack for my 2017 BMW i3 has been flawless. The range is now 320km (up from 190km), and the installation was simpler than I expected. The 2-year warranty gives me peace of mind, and customer service is responsive when I have questions.”
