1. A battery connection module, comprising:
a carrying tray;
a plurality of busbars provided to the carrying tray; and
a flexible circuit board provided to the carrying tray and comprising a main board body and a plurality of connecting board bodies integrally connected to the main board body in a floatable manner and respectively electrically connected to the plurality of busbars, each connecting board body being provided to a longitudinally extending side edge of the main board body, extending in a longitudinal direction and facing the corresponding busbar in a transverse direction, each connecting board body having a central portion having first and second opposite sides, an inner side edge extending therebetween and an opposite longitudinally extending outer side edge, and first and second cantilevered portions respectively extending longitudinally from the first and second sides of the central portion in the longitudinal direction, the outer side edge of each connecting board body being generally flush with the longitudinally extending side edge of the main board body, each cantilevered portion having a proximal segment, a distal segment and a curved segment extending between the proximal segment and the distal segment, wherein in each connecting board body 1) the proximal segment of each cantilevered portion extends from and is connected to the respective side of the central portion at the outer side edge of the central portion to be close to the corresponding busbar in the longitudinal direction and 2) the curved segment extends along at least the longitudinal direction and the transverse direction, wherein each connecting board body is connected to the main board body only by the distal segments of the first and second cantilevered portions, and wherein a gap is formed between each connecting board body and the main board body.
