Revive Your BMW i3: Premium Battery Upgrades with 2-Year Warranty
Is Your BMW i3 Losing Range? You’re Not Alone
Imagine driving your BMW i3, only to find yourself stranded with a battery that barely makes it to the grocery store. Many BMW i3 owners face this exact frustration as their original battery degrades over time. The factory battery might have been impressive in 2014, but after 5-7 years of daily use, it’s common to see range drop from 180km to just 100km or less. What’s worse? Replacing it with an OEM battery can cost upwards of $12,000, a price that makes many owners consider trading in their beloved electric vehicle.
Why Upgrade Your BMW i3 Battery Now?
The Reality of Battery Degradation
Unlike gasoline engines, electric vehicle batteries don’t simply “die” – they gradually lose capacity. Most BMW i3 owners notice a significant drop in range after 5-6 years of regular use. The original 180km range becomes a 120km range, making daily commutes stressful and weekend trips impossible without multiple charges.
The CNS BATTERY Solution
CNS BATTERY offers a premium alternative to expensive OEM replacements. Our 45kWh, 50kWh, and 62kWh battery packs for BMW i3 models use brand-new CATL lithium cells – the same quality used by top EV manufacturers worldwide. Unlike refurbished batteries that often swell or fail within months, our batteries are built for long-term reliability.
What Makes CNS BATTERY Different?
Genuine OEM Compatibility, Not Just a “Similar” Product
Many competitors claim “OEM compatibility,” but they often use mismatched components that cause issues with your vehicle’s BMS (Battery Management System). CNS BATTERY’s battery packs are engineered specifically for BMW i3, with perfect connector matching and seamless BMS integration. As one satisfied customer from Berlin noted: “The wiring connectors were a perfect match for the original factory parts, requiring no modifications.”

Real Results, Real Users
“After the original battery degraded, the 4S dealership quoted €12,000 for a replacement. My friend recommended CNS, so I decided to give them a try. Unexpectedly, the brand-new CATL battery cells were of the same quality as the original. Now, the full charge range has increased from the original 180km to 290km, and I only need to charge it once a week for daily commuting.” – Lisa K., BMW i3 (2017 model)
