The invention discloses a battery pack with a temperature controller and used for an electric bamboo raft. The battery pack comprises a battery pack shell and is characterized in that a power battery pack, a temperature control water pipe, a peristaltic pump and an AC/DC converter are arranged in the battery pack shell; the power battery pack is formed by parallel connection of at least two single battery units, and each single battery unit is formed by series connection of at least two single batteries; the temperature control water pipe is arranged on the periphery of the single battery units; the peristaltic pump is communicated with the temperature control water pipe, and direct current of the power battery pack is converted into alternating current which is then supplied to the peristaltic pump; the power battery pack is electrically connected with the AC/DC converter which is electrically connected with the peristaltic pump. The battery pack has advantages that temperature uniformity of the single batteries in the power battery pack of the electric bamboo raft can be improved, and the service life of the power battery pack is prolonged.
