The Samsung SDI INR18650-30Q is a rechargeable lithium-ion cell developed for power-tool battery systems. It combines 3000mAh nominal capacity, 3.6V nominal voltage, a 15A maximum continuous-discharge rating and initial AC impedance of no more than 26mΩ. Its balanced energy and current capability supports professionally engineered portable-power and industrial battery packs when installed with appropriate protection, temperature monitoring and welded interconnects.
The INR18650-30Q provides at least 3000mAh when discharged at 600mA to 2.50V after standard charging. At its 3.6V nominal voltage, this corresponds to approximately 10.8Wh of calculated nominal energy, supporting longer runtime than lower-capacity high-drain 18650 cells.
Samsung SDI specifies a maximum continuous-discharge current of 15A at 25°C. The cell also delivered approximately 95% relative capacity during a 20A capability test, but 20A is not identified as its continuous rating. Pack current should be derated for temperature, ageing and cooling conditions.
Rated discharge capacity is at least 2900mAh when the cell is discharged at 10A to 2.50V at 25°C. This high-current test condition gives pack designers a more relevant capacity reference than the lower-current nominal-capacity test when estimating runtime in demanding equipment.
Standard CC-CV charging uses 1.50A, 4.20V and a 150mA termination current, with a stated charging time of approximately 180 minutes. The rapid-charge condition uses 4A and a 100mA cut-off for approximately 70-minute charging at 25°C under controlled conditions.
Initial AC impedance is specified at no more than 26mΩ when measured at 1kHz after standard charging. Under standard charge and 15A maximum continuous discharge, the datasheet specifies at least 1800mAh remaining capacity after 250 cycles at 25°C.
Samsung’s pack guidance specifies voltage monitoring, over-temperature and over-current warnings, secondary protection and more than 1mm spacing between cells. The bare cylindrical cell must use welded terminal connections and should be positioned away from heat sources, with mechanical protection against shock and sleeve damage.
Custom battery pack applications: Suitable applications include cordless power tools, professional cleaning equipment, portable industrial machinery and other medium-to-high-current systems with validated electrical and thermal requirements. MisenBattery supplies Samsung SDI cells and supports custom pack integration using a matched BMS, fuse protection, welded interconnects, voltage and temperature sensing, cell insulation, more than 1mm spacing, and suitable thermal and mechanical design. Supporting CE, UN38.3, RoHS and UL documentation can be provided for the applicable product and shipment.
