Key Features of Semco SI BE 7-24S 10A
During the charging process, the voltage rise speed of each cell is different, which results in the increase of the voltage difference of the battery pack. The highest voltage series of single body triggers the BMS over- voltage protection in advance, which causes the whole group of batteries to stop charging. The low voltage monomer cannot be full of electricity, and the high voltage monomer cannot discharge the power. The battery capacity is reduced and the life is reduced. Equalization is the key technology to solve the difference of cell unit. The common methods are discharge equalization and charging equilibrium. The balance has the effect of balancing voltage on the lithium battery group, so as to achieve the effect of full charge and full discharge of battery capacity, and make the battery group recover the maximum capacity and extend the service life of the battery pack.
Cell Aging Machines are designed to stabilize lithium-ion cells through controlled charge and discharge cycles, validating capacity, voltage consistency, and thermal behavior before assembly.

Battery Pack Testers perform complete electrical and safety validation, including voltage, current, insulation resistance, and protection checks.
