An electric kart (100, 200), comprising: a frame; a driver seat mounted to the frame; two front wheels and two rear wheels operatively connected to the frame; an electric motor operatively connected to the two rear wheels to drive the two rear wheels; and at least one battery (122, 124) operatively connected to the electric motor to power the electric motor to drive the electric kart, the at least one battery (122, 124) including: a support structure mounted to the frame of the electric kart; a first plurality of battery cells and a second plurality of battery cells positioned on the support structure; a first heat exchanger and a second heat exchanger positioned on the support structure, the first plurality of battery cells being disposed inside the first heat exchanger, the second plurality of battery cells being disposed inside the second heat exchanger, the electric kart (100, 200) being characterized in that: an air passage is defined between the first plurality of battery cells and the second plurality of battery cells, the air passage being configured such that motion of the electric kart induces airflow through the air passage to cool at least some battery cells of at least one of the first and second pluralities of battery cells; the first heat exchanger and the second heat exchanger define the air passage therebetween; the support structure includes a bottom portion mounted to the frame of the electric kart and a top portion spaced from the bottom portion; the first heat exchanger includes a first sleeve that extends between the bottom and top portions (144a, 144b) of the support structure; the second heat exchanger includes a second sleeve that extends between the bottom and top portions (144a, 144b) of the support structure; the first plurality of battery cells is received in the first sleeve; and the second plurality of battery cells is received in the second sleeve. a frame; a driver seat mounted to the frame; two front wheels and two rear wheels operatively connected to the frame;
