A method of operating a machine battery system having a plurality of battery packs connectable in parallel includes: online a first battery pack having a highest offline pack voltage for discharging, a pack controller circuit including the first battery pack online one or more individual battery strings of the first battery pack; when the next highest offline pack voltage is within a predetermined discharge threshold voltage of the load voltage, online a next battery pack having the next highest offline pack voltage, including a pack controller circuit online one or more individual battery strings of the next battery pack; and when the next highest offline group voltage is less than the predetermined discharge threshold voltage of the load voltage, waiting to make the next battery pack online until the next highest offline group voltage is within the predetermined discharge threshold voltage. 一种操作具有可并联连接的多个电池组的机器电池系统的方法，包括：使具有最高离线组电压的第一电池组在线以用于放电，包括第一电池组的组控制器电路使第一电池组的一个或多个个别电池串在线；当下一最高离线组电压在负载电压的预定放电阈值电压内时，使具
