SICA ENERGY / BATTERY CELLS
Cylindrical battery cells
SICA Energy supplies cylindrical lithium-ion cells for OEM battery-pack projects. Compare eight models in 18650, 21700 and 32700 formats by capacity, discharge current and installation requirements.
Compare capacity, voltage, discharge current, cutoff voltages, dimensions and weight across three cylindrical formats.
