A lithium battery manufacturer that actually replies

Buying batteries from China can feel risky. For example, you send an inquiry, wait days for an answer, and still aren’t sure what grade of cells you’ll get.

That’s why we built Synergy Technology differently. Since 2019, we have worked as a lithium battery manufacturer and exporter in Longgang, Shenzhen.

With us, you talk to our team directly. Our export staff reply within 2 hours and explain every spec in plain terms. They also send inspection photos before your order leaves the factory.

Why importers pick us as their lithium battery manufacturer

Factory prices, no middleman

You buy directly from our Shenzhen factory. As a result, no trading company adds its own margin to your price.

Grade A cells you can check

We only use Grade A LiFePO4 cells. Before shipping, we also send inspection photos so you see exactly what you get.

Certified for global markets

Our products carry CE and IEC certification. Because of this, customs clearance is smoother in most countries.

Small orders are welcome

Want one sample first? That’s fine, because we handle samples, small batches and full containers.

We handle the export paperwork

Our team prepares the export documents and helps with customs questions. So you don’t need import experience to work with us.

Your brand, your specs

In addition, we offer OEM and ODM, so you get custom packs with your own logo, size and specs.

ESS battery supplier for home and commercial solar

Solar panels only work while the sun is out. However, a good ESS battery stores that power, so you can use it at night or during power cuts.

We supply ESS batteries to solar installers, distributors and project companies. For example, some need ten home batteries a month, while others need a 500kWh system for a factory. Either way, we plan each order around your project.

We export lithium batteries worldwide

Our batteries are working in homes, shops and factories across these regions.
