A battery pack and connecting circuits of battery modules. The battery pack includes a plurality battery modules connected in series, wherein each battery module is provided with a connecting circuit. When the battery module operates normally, the connecting circuit serially connects the current battery module to the previous battery module and the succeeding battery module. When the battery module operates abnormally, the connecting circuit selectively disconnects the battery module, and if it disconnects the current battery module, it directly connects the previous battery module and the succeeding battery module in series. When a battery module is damaged abnormal, the current damaged battery module can be disconnected from the series battery pack and bypassed. As such, the previous battery module may be directly connected with the succeeding battery module, ensuring the normal connection of the series circuit.
