The ADC-16 Battery Management System allows a conventional desktop or laptop PC to be used to select individual batteries or individual battery cells for the purpose of measuring voltage levels, charging and logging. Set points are provided for charge adjustment of individual batteries or cells. Maximum charge levels and maximum service life of the battery bank are maintained with regular use of the system. Applications include electric vehicles, electric fork lifts, golf carts, electric industrial equipment, battery backup systems for computers or other equipment. The system's data logger provides data on individual batteries or cells to pin point problems or battery failure.
