Revitalize Your BMW i3: Premium Battery Upgrade with 300+ km Range & 50% Cost Savings
The Heartbeat of Your BMW i3 is Fading – Here’s the Fix
Ever find yourself planning your day around charging stops? You’re not alone. As your BMW i3 ages, that once-proud 180km range dwindles to 120km, turning daily commutes into anxiety-inducing logistics. The frustrating truth? Replacing your battery with an OEM option costs $12,000+ – but what if you could double your range for less than half the price?
Why Your BMW i3 Needs a Battery Upgrade Now
Battery degradation is inevitable, but it doesn’t have to mean trading in your beloved i3. After 5-7 years of use, most BMW i3 owners face the same dilemma: pay thousands for a factory battery or accept reduced range. The reality? CNS BATTERY’s OEM-compatible solutions deliver genuine performance at 50%+ lower costs without compromising safety or compatibility.

Frequently Asked Questions
Q: How long does installation take for a complete battery pack?
A: Complete battery packs are plug-and-play – most owners install them in 90 minutes. For individual battery modules, expect 2-3 hours with basic tools. We provide detailed installation videos and wiring harnesses with every order.
Q: Is the warranty really 2 years or 80,000 km?
A: Yes. Our warranty covers manufacturing defects and guarantees your battery will maintain at least 9 out of 12 capacity bars after a full charge for the warranty period. It’s non-transferable and applies only to the original purchaser.
Q: Can I install this myself if I’m not a mechanic?
A: Absolutely! We’ve designed our battery packs to match your original factory connectors. The installation video shows every step in detail, and our technical team provides remote support during installation.
Q: How does the range compare to OEM batteries?
A: Our 62kWh battery delivers 310km+ range in real-world conditions, compared to the OEM’s 180km when degraded. Even our 45kWh option provides 290km, significantly outperforming the original battery’s degraded capacity.
