Customer Reviews
Don’t just take our word for it. Here is what some of our satisfied customers have to say about our products and services:
- Mark T. (California, USA): “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, less than half the price of the original. Now, the full charge range is 430km, slightly less than the official 440km, but more than enough for daily commuting.”
- Tom H. (Texas, USA): “I used to struggle for ages just to change a car light bulb, so for something as major as changing the battery, I initially wanted to find a professional mechanic. But the installation fee was £800, which I thought was too expensive. Following the video, it took me 1 hour to remove the old battery and another hour to install the new one. Now the full charge range is 430km, 200km more than before.”
- Lisa K. (Berlin, Germany): “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.”
