Shenzhen Weijie Technology has recently launched a new series of heavy-duty power tool battery packs and complete supporting accessories, creating long-lasting power supply solutions for industrial construction, garden machinery and outdoor engineering equipment. The cells are connected via high-precision laser welding, equipped with genuine Renesas protection ICs and multi-layer safety circuits to resist high current impact, featuring large capacity, low energy loss and ultra-long cycle life. Stable discharge performance is maintained even during long-hour heavy-duty operation.

We supply battery packs with various capacity specifications for electric drills, cutting machines, grinders and other power tools, along with complete supporting parts including dedicated chargers, replacement housings and protective cables. Leveraging our mature underlying chip development capability, we adjust battery output curves according to customers’ equipment parameters and support personalized customization on appearance, voltage and capacity. All lithium cells are sourced from top manufacturers and pass multiple safety tests including extrusion, high temperature and overcharge. Our batteries adapt to harsh environments such as high outdoor temperature and bumpy construction sites, reducing equipment failure rates and improving the market competitiveness of power tool brands.
