Is Your Nissan Leaf or BMW i3 Struggling with Range? Upgrade to a CNS Smart Battery Today
As an electric vehicle owner, you know the frustration of range anxiety all too well. Your dashboard lights up, the charging stations are few and far between, and suddenly, your freedom is limited. You’re not alone. Many Nissan Leaf and BMW i3 owners face this daily battle as their original batteries degrade over time.
But what if you could turn back the clock on your EV? Imagine doubling your range, eliminating the fear of being stranded, and doing it all for less than half the cost of a factory replacement.
At CNS BATTERY, we don’t just sell batteries; we provide freedom. We are a leading manufacturer specializing in high-performance, Original Equipment Manufacturer (OEM) compatible lithium-ion power batteries. For over a decade, our team has been dedicated to solving the battery degradation problem for Nissan and BMW owners worldwide.
Why Choose CNS BATTERY?
When it comes to replacing your EV battery, you have options. But not all options are created equal. Here is why thousands of satisfied customers choose CNS:
- Unbeatable Value: Save 50%+ compared to the original manufacturer’s price without sacrificing quality.

The CNS Smart Battery Difference
Unlike generic replacements, our batteries are designed with the modern driver in mind. We understand that today’s drivers want to know exactly how their vehicle is performing. That is why our advanced battery management systems (BMS) are designed for seamless integration and monitoring.
Real-Time Performance Monitoring

Hear From Our Happy Customers
Don’t just take our word for it. Here is what Mark T. from California had to say about his upgrade:
“The original battery in my car lasted 8 years, but the range had dropped to only 120km… Replacing it with an original manufacturer battery would cost $16,000, which was ridiculous! After comparing options, I chose a 62kWh battery from CNS, which cost only $7,800… Now, the full charge range is 430km… The 2-year/80,000km warranty is reassuring.”
