🚗 Worried about long shipping times from China to Europe?

We understand.

Sea freight can take around 2 months, and for customers looking to upgrade an aging BMW Hybrid battery, waiting that long isn’t always ideal.

That’s why we prepared ahead.

🔋 120 BMW Hybrid battery modules have already been shipped to our warehouse in Poland 🇵🇱

With local stock available, European customers can receive their batteries in around 10 days, depending on the destination.

From Lisbon to China — a partnership that keeps growing. 🇵🇹🇨🇳

Meet Gonçalo, our workshop partner from Lisbon, Portugal.

Our cooperation started about a year ago with a BMW i3 battery upgrade. After a successful installation, we worked together again on a Porsche Hybrid battery — also successfully installed. His next BMW Hybrid battery is already on its way to Portugal, with installation coming soon.

This time, Gonçalo came to China to visit our factory and warehouse, see our production process in person, and discuss deeper cooperation with MTG.

And he’s also looking forward to what’s next. 👀Our Universal Range-Extender Pack is currently under testing, and we’re working to make it ready.

Stay tuned for more updates.

🔋 A Look Into the Future of Energy Storage

Our team recently visited Solar & Storage Live Guangzhou 2026 and took a closer look at the energy storage solutions.

For us, exhibitions give us an opportunity to meet people in the industry, and discover new possibilities for battery applications.

From EV batteries to energy storage, we’re continuing to explore what’s next.

The battery world is evolving — and we’re keeping up. ⚡

❄️ Winter can reveal what your battery has been hiding.

When temperatures drop, your BMW may use more energy for heating, while cold conditions can also affect battery efficiency. And if your hybrid battery is already aging, you may notice the difference even more.

With an MTG BMW Hybrid Battery, you can replace an aging or damaged battery and help restore your battery system’s performance.

🔋 Restore the battery.
🚗 Keep the BMW you love.

If you're experiencing battery-related issues with your BMW Hybrid, feel free to DM us to learn more about your options.

Today, we have:
🔋 More products
