Note:
(1) Do not use over voltage and overload, otherwise it will damage the battery and power supply.
(2) The module can only step-down voltage but not boost voltage, and cannot supply power to the electrical equipment higher than the input voltage.
(3) Pay attention to ventilation and heat dissipation when working with large current and high power for a long time, so as to prolong the service life of the power supply.
(4) Do not work at full load for a long time. Please leave 20% allowance when working continuously. Pay attention to ventilation and heat dissipation
