Why Our BMW i3 Batteries Outperform the Competition

✅ Simple Installation, No Special Tools Required
Our battery modules are designed for easy installation:
- Plug-and-play for complete battery packs
- 6 power lines + 1 signal line for individual modules
- Detailed video tutorials and 24/7 technical support
As one satisfied customer in Berlin shared: “The wiring connection problems during installation were resolved within an hour through remote video guidance. The full charge range increased from 180km to 290km – it’s like having a new car!”
✅ Superior Warranty Protection
We back our batteries with a comprehensive 2-year / 80,000-mile warranty – longer than most OEM options. If your battery doesn’t meet our performance standards, we’ll replace it with no hassle.
Real Results from Real BMW i3 Owners
“After my original battery degraded, the 4S dealership quoted €12,000 for replacement. I chose CNS, and the new CATL cells were of the same quality as original. The sea shipping took 6 weeks, but the packaging was robust. Now, the full charge range has increased from 180km to 290km – I only need to charge once a week for daily commuting.” – Lisa K., BMW i3 (2017 model)
“The installation was straightforward with the video tutorial. Connecting the 6 power lines and 1 signal line was simple. The only drawback was sea shipping took 8 weeks – if you need it urgently, choose expedited service.” – Javier R., BMW i3 (2018 model)
