Why Most Lithium Batteries Are Made in China (and How to Pick a Brand That Lasts)

Confused by the wild-west lithium battery market in the US? You’re not alone. It is easy to be overwhelmed by the flood of cheap, low-quality lithium battery brands—most of which disappear in just a few years. We took the opportunity to sit down with Pylontech’s Director of North American Sales, Sam Buffington, to break down what’s really happening behind the scenes.

Watch to learn why lithium batteries are made in China and why vertical integration and rigorous quality control are critical for long-term performance. We discuss why Pylontech’s active battery management system (BMS) sets it apart and how cell testing and sorting ensure reliability well beyond industry averages.

Lithium batteries are a long-term investment that benefit from an approach that takes into account the lifetime costs of ownership. In this video, we discuss the real cost of choosing a low-quality brand: from high failure rates to weak warranty support, to provide a full picture from the perspective of industry insiders. In contrast, you’ll also hear how Pylontech’s non-prorated warranty, U.S.-based technical support, and 9-year proven integration with Victron Energy make it a dependable choice for installers and homeowners who want lithium systems that they can rely on in the long run.

If you’re deep into researching residential lithium battery systems or commercial lithium battery solutions, we hope this conversation will help you to avoid costly mistakes and gain some peace of mind in choosing a battery brand that’s more than its marketing.
