Series-connected storage battery set

The utility model discloses a storage battery set, in particular a series-connected storage battery set. The utility model provides an anti-impact series-connected storage battery set which comprises storage batteries, and bridge connection boards arranged between the storage batteries, wherein the bridge connection boards are provided with through holes, and an arc-shaped structure penetrating though the bridge connection boards is arranged at the middles parts of the bridge connection boards. In the series-connected storage battery set, since the arc-shaped bridge connection boards are used, and the arc-shaped structure can elastically deform under stress, the acting force received by the storage batteries can be buffered, and storage battery nuts can be prevented from loosening, therefore, the series-connected storage battery set can be normally used after being impacted. The bridge connection boards can be used in an overlaid way, different conducting requirements and buffering requirements can be met, an
