Samsung SDI

Samsung SDI’s high-power cylindrical battery

In 2005, Samsung entered the power tool market by successfully developing a lithium-ion battery for power tools for the first time in Korea. Power tools require high power and safety since they are used for drilling concrete, cutting trees or grinding metal. Therefore, a long-standing and high-power battery is needed for a power tool to make a strong and instant power.

StorTronics is an ISO 9001:2015 certified company that can safely design your custom battery pack around these Samsung SDI cells.
