Revitalize Your BMW i3: OEM-Grade Battery Upgrade Kit for Maximum Range & Reliability
Tired of Constantly Recharging Your BMW i3?
If you’re a BMW i3 owner experiencing shorter driving ranges, frequent charging stops, or battery degradation after just a few years, you’re not alone. Many drivers face this frustration when their original battery starts to lose capacity. But what if you could extend your range by 50% or more without replacing your entire vehicle? The solution is closer than you think.
Why Your BMW i3 Deserves a Premium Battery Upgrade
Your BMW i3 was designed for efficiency, but as batteries age, their performance inevitably declines. Most owners face this reality after 5-7 years of use, when the battery’s capacity drops to 70-80% of original capacity. This means longer charging times, reduced range, and the constant worry of being stranded.
The OEM battery replacement from BMW can cost upwards of $12,000 – a price tag that makes many drivers consider trading in their vehicle. But there’s a smarter, more cost-effective solution that delivers factory-quality performance at a fraction of the cost.
The CNS BATTERY Advantage: Premium Performance at 50% of OEM Cost
Unlike other aftermarket options that use refurbished or low-quality cells, CNS BATTERY uses brand-new CATL lithium cells – the same cells used by leading EV manufacturers worldwide. This ensures:
- True OEM compatibility with all BMW i3 models (2014-2023)
- Extended battery life with minimal degradation
- Real-world range improvement from 180km to 290km+ on a full charge
- 2-year/80,000km warranty – longer than most competitors
Our 45kWh, 50kWh, and 62kWh battery packs are engineered to match your vehicle’s specifications precisely, ensuring seamless integration with your BMW i3’s BMS (Battery Management System).
Installation Made Effortless: No Expertise Required
Many DIY enthusiasts hesitate to replace their EV battery due to fear of complex installation. With CNS BATTERY, installation is remarkably straightforward:
- Complete battery packs are plug-and-play – simply connect and go
- Battery modules require only 6 power lines and 1 signal line connection
- Comprehensive video tutorials guide you through every step
- 24/7 remote technical support from our engineers
As one satisfied BMW i3 owner in Berlin shared: “The installation was completely hassle-free. The engineer guided me through the wiring step by step via video call, making it completely effortless. Now, the full charge range has increased from the original 180km to 290km.”
Real Results, Real Satisfaction
Don’t just take our word for it. Here’s what actual BMW i3 owners say about their CNS BATTERY experience:
“After the original battery degraded, the 4S dealership quoted €12,000 for a replacement. CNS provided a brand-new CATL battery of the same quality as the original. The installation was smooth with remote video guidance, and the range increased from 180km to 290km. The sea shipping took 6 weeks, but the packaging was robust, and the battery arrived undamaged.” – Lisa K., BMW i3 (2017 model)
“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. The sea shipping took 6 weeks, and the packaging was a fumigation-free wooden crate, so the battery arrived without any damage. The most surprising thing is the lifetime technical support.” – Lisa K., BMW i3 (2017 model)
