Description
1. Product Highlights
The measurement circuit draws power from the power input port and does not require an additional power cord.
With LCD display, you can display information such as voltage, current, power, discharge mAH, discharge time and operating temperature.
The protection mechanism is complete, with various protections such as undervoltage protection, overvoltage protection, overcurrent protection, overpower protection, overtemperature protection, overtime protection and over capacity.
Overcharge and overdischarge control of the battery can be achieved by setting appropriate undervoltage protection and overvoltage protection thresholds.
Timing and quantitative battery charging and discharging can be achieved by setting appropriate timeout protection and over capacity protection thresholds.
Display information such as voltage, current, power, store mAH, discharge time and operating temperature.
Undervoltage protection, overvoltage protection, overcurrent wave Ahu, overpowered wave Ahu, over temperature protection, overtime protection and over capacity protection. Overcharge and overdischarge control of the battery can be achieved by setting appropriate undervoltage protection and overvoltage protection thresholds.

3. Product Features
1, LCD display
In normal mode, the LCD displays the input voltage and operating temperature on the upside; the downlink shows the real-time current, power, capacity, and discharge time.
In protected mode, the LCD displays the protection code.
In the setting mode, the LCD displays various setting parameter codes and parameter thresholds.
2, sound and light alarm
When the output of the voltage ammeter is turned on, the RUN indicator is always on and the buzzer is not ringing; when it is off, the RUN indicator is off and the buzzer is not ringing. After entering the protection mode, the buzzer will drop the alarm and the RUN indicator will flash.
3, charge and discharge capacity and time automatic statistics, as long as the output is turned on (RUN indicator is always on) to start statistics, turn off the output (RUN indicator is not lit), stop statistics, power-down statistics are automatically cleared, in the display capacity and time When the interface is pressed, long press the button - the corresponding data can be cleared. Please clear the statistics before starting the statistics. The maximum discharge capacity (OAH) and maximum discharge time (OHP) can be set to on or off in the setting mode (default off). After opening, the threshold value can be set. When the threshold is exceeded, the output is automatically turned off and the buzzer alarms. The battery is charged and discharged.
4. By setting the appropriate overvoltage protection threshold and undervoltage protection threshold, the overcharge and overdischarge control of the battery can be realized. For detailed operation, please refer to 4.4 Product Application Example.
5. Perfect software and hardware protection mechanism, and the software protection threshold can be adjusted. After software protection, the output is turned off.
Hardware protection:
The module input port has anti-reverse protection, and the reverse connection does not burn.
Software protection:
OVP over-voltage protection (default 38V, can be set by yourself, after over-voltage protection, RUN indicator flashes, LCD interface displays OVP. In battery charging, setting the appropriate threshold can effectively prevent battery overcharge);
OCP overcurrent protection (default 5.5A, can be set by yourself, after overcurrent protection, RUN indicator flashes, LCD displays OCP);
OPP over power protection (default 200W, can be set by yourself, after over power protection, RUN indicator flashes, LCD displays OPP);
OTP over temperature protection (default 80 °C, can be set by yourself, after over temperature protection, RUN indicator flashes, LCD shows OTP);
LVP undervoltage protection (default 4.8V, can be set by yourself, after undervoltage protection, RUN indicator flashes, LCD shows LVP, in battery discharge test and other applications, set the appropriate LVP, can effectively prevent battery over-discharge, so as not to damage the battery )
6. The voltage and current meter output is enabled by default.
7, all settable parameters support power-down storage.
