Features NOTE: This product is a voltage controller, which turns on and off the output through a relay, which only acts as a switch and cannot change the voltage. In addition, if you have any questions in use, please contact us at the first time. OVER DISCHARGE PROTECTION: When the battery is under voltage loss or low battery, it will be automatically disconnected,This battery controller provides a high degree of flexibility in terms of discharging modes and parameter settings. Users can easily set the parameter to disconnect the battery automatically when it reaches a preset voltage, MEMORY FUNCTION:With power-off protection, it will save your settings in the event of an unexpected loss of power. This feature is crucial for electronic devices that require specific configurations, as it prevents the loss of critical data and allows you to resume work where you left off. Main functions: over charge protection, over discharge protection function, short circuit protection function, over current protection function This product can effectively protect the circuit, and the method of use is convenient and practical Specifications: Material: Plastic Supply voltage: 12-36V battery Output voltage: equal to the supply voltage Control accuracy: 0.1V Power: ＜1.5W Scope of application: various batteries lithium battery Net weight: approx. 28g / 1.0oz Product size: approx. 57*42*19mm / 2.2*1.7*0.7in Package list: 1 * Overcurrent Protection Module Note: 1.Please allow 0-1 inch error due to manual measurement.
