Stacked pouch cell battery technology provides a low impedance construction, meaning that the rate of flow of electrons is much higher thanks to the innovative internal pouch battery connectors and electrodes, providing a greater surface area vs a traditional cylindrical battery cell type. It also benefits from superior thermal performance vs cylindrical batteries. This increases battery durability, improves the cycle life and results. Also comes with 1 x TSTAK Kitbox.
