1 Product Introduction
This 18S 66.6V 39Ah lithium battery pack is professionally engineered to deliver dependable high power output tailored for heavy-duty industrial equipment and diverse electric mobility applications. It can sustain up to 3C maximum continuous discharge current while keeping steady voltage performance under high-load conditions, and offers 1C standard charge and discharge capability to reliably meet the demands of regular daily routine operation. The battery is set with a 76.5V limited charge voltage and a 49.5V cut-off voltage, which work to shield the internal cell system from damaging voltage extremes and effectively prolong the overall service life of the battery pack.
Every unit of this battery pack is manufactured under rigorous, full-process quality control standards within our production facility. We provide direct factory supply, cutting out extra markup from intermediate distributors to reduce procurement costs for buyers. It comes with compact dimensions of 201*90*213mm and a total weight of 8.11kg, making it easy for flexible installation and layout in projects with tight or confined space scenarios. The built-in integrated protection mechanism actively safeguards the battery against overcharge, over discharge, over current and short circuit risks, ensuring continuous, stable and safe power supply for your industrial equipment, electric vehicles and stationary energy storage projects. We offer fully customized battery solutions that can be adjusted to fit your unique power and dimensional requirements, alongside consistent after-sales technical support accessible for our clients across the globe.
