[0002] A water propeller is used to provide power for a paddle board, a kayak, etc., so that the paddle board, the kayak, etc. move forward. At present, some existing water propellers have a built-in battery, but the battery life is not high. When the internal battery runs out of power, it needs to be charged by connecting the power cord on the water propeller to the battery adapted for the propeller. Some water propellers need to be connected to the adapted battery to drive and work when in use. And after the propeller is connected to the battery, the battery supplies power to the propeller and drives the propeller to work.

[0003] However, at present, the existing batteries used for propellers do not have a wireless control function. When users use them, they need to externally connect a wireless receiving device to the battery through a battery cable, so that users can control the battery to supply power to the propeller through a wireless transmitting device adapted to the wireless transceiver device. This is inconvenient for users to install the battery and the propeller on the paddle board for use, and increases the cost of using the paddle board with the battery. Moreover, the existing batteries adapted for propellers cannot float automatically after falling into the water, and users have no way to recover them, which affects the use experience of the batteries for propellers.

[0032] In the present utility model, a wireless module 7 for wireless communication with an external device is directly configured on the battery. After the battery is electrically connected to the thruster, a wireless signal sent by the external device to the wireless module 7 is received by the wireless module 7, and the wireless module 7 processes the wireless signal and then transmits it to the main control circuit board 8. The main control circuit board 8 outputs the electrical energy of the battery cell 6 through the power output interface 2 or turns off the electrical energy output of the battery cell 6 according to the signal transmitted by the wireless module 7, so as to drive the thruster to work or turn off the thruster, which is convenient for users to operate, without the need to purchase additional wireless devices, saving costs.
