Who Actually Makes the Battery in a Chinese EV?
When someone hears "Chinese EV", the battery flinches first: "it'll die in 3 years, it'll catch fire, no one here can fix it, it's a no-name black box." It is the most common fear — and, it turns out, the least justified. This guide explains, honestly and in plain words, what is really behind the battery, how long it lasts, why it isn't a "fire-bomb", and who stands behind it under warranty.
It's the same battery as in a Tesla — meet CATL
The battery in most of these cars is made by CATL (Contemporary Amperex Technology) — the world's largest battery maker. This is not a startup experiment: it is the most-used EV battery on Earth, already in millions of cars on European roads.
CATL supplies the very same cells to Tesla, Volkswagen, Mercedes and BMW. The Chinese maker buys from the same shelf the Germans do. Very often a "Chinese battery" and "the battery in a European EV" are the exact same cell from the exact same factory — only the badge on the hood differs.
In other words: you may never have heard of this car brand, but you have probably been "driving" its battery for years — just in another car with a more familiar logo.
Will the battery be dead in 3 years? The actual math
Short answer: no. Real-world degradation is about 5–10% of capacity per 100,000 km. That means after 100,000 km a battery still holds roughly 90–95% of its original range. It is a slice off the top, not "half the car", and most owners never notice it day to day.
And it isn't just math on hope. These models use LFP chemistry, which the industry chose precisely because it lasts longer and handles frequent charging well. You don't have to babysit it the way people imagine — it can be charged to 100% every day without harm.
You also aren't betting on statistics alone: a factory warranty of 3 years / 100,000 km covers underperformance within that window. If the battery doesn't deliver what was promised, that is the maker's problem, not yours.
What LFP is, and why it's the safer chemistry
Those scary EV-fire videos are almost always older NMC (cobalt) batteries. These cars use LFP (lithium iron phosphate) chemistry — it runs cooler and is far more resistant to thermal runaway, the chain reaction that causes a fire.
LFP is trusted enough that Tesla itself put it in its standard, high-volume cars — for exactly this reason. Safe enough for Tesla's volume model, safe enough here.
In practice this means less worry: the battery can be safely charged to full, it copes better with heat, and it is simply not "the battery you've seen on the news". BYD's Blade battery, made by another major Chinese player, is also LFP and structurally very safe — showing LFP is not a niche choice but the direction of the industry.
CATL batteries in our models
Here is what it looks like with real, in-stock cars. The figures are specific, and the price always sits beside a named Western rival's price — compare for yourself:
For example, the Xiaomi SU7 Max with a 101 kWh CATL battery is €39,100. In the comparable class, the BMW i4 is €55,000. Both are powerful electric cars — only the SU7 Max's battery comes from the same factory that supplies the Germans.
What the warranty covers, and who services it
All of these models carry a factory warranty of 3 years / 100,000 km covering battery underperformance and defects. It is comparable to what a new European car gives.
Service is handled in the EU by the local partner — diagnostics, warranty work and parts are dealt with here, not by shipping the car to China. This answers the last, deepest question: "who fixes it here?"
The car arrives EU-registered and road-ready. In short: the same battery as a Tesla, honest math on degradation, the safer chemistry, and real warranty cover with EU service.

Frequently Asked Questions
Is a Chinese EV battery the same as the one in a Tesla?
Very often, literally yes. Most cells in both a Tesla and many Chinese models are made by CATL — the world's largest battery maker. It is not a "different" battery: it is the same cell from the same factory, just a different badge on the hood. CATL also supplies VW, Mercedes and BMW.
How long does an EV battery actually last?
Real-world degradation is about 5–10% per 100,000 km — a slice off the top, not "half the car". After 100,000 km a battery typically still has 90–95% of its capacity. The LFP chemistry these models use was chosen precisely because it lasts longer and handles everyday charging well.
Is an LFP battery safe? Can it catch fire?
LFP (lithium iron phosphate) chemistry is among the safest in the mass market: it runs cooler and is far more resistant to thermal runaway than the older NMC (cobalt) batteries usually behind fire headlines. It is trusted enough that Tesla itself uses LFP in its standard cars.
What does the 3-year / 100,000 km warranty cover?
The factory warranty (3 years / 100,000 km) covers battery underperformance and defects within that window — if it doesn't deliver what was promised, that is the maker's problem, not yours. It is comparable to a new European car's warranty cover, and service is handled in the EU by the local partner.
Which in-stock models use a CATL battery?
For example: the Xiaomi SU7 Max with a 101 kWh CATL battery, the Deepal S07 with a ~80 kWh CATL battery, and the AVATR 06 with a 72.9 kWh CATL battery. All come with the same 3-year / 100,000 km warranty and EU service.
Can I charge an LFP battery to 100% every day?
Yes. Unlike older chemistries, LFP tolerates daily 100% charging well — makers even recommend it so the charge readout stays accurate. That means less babysitting and less worry compared with the batteries people fear.
