Specifications: Name: Battery Charging Control Module Control voltage: 6-60V Control current: 10A Control accuracy: 0.1V Voltage deviation: 0.1V Application: various storage batteries and batteries lithium Size: approx. 7 * 4.8 * 1.7cm / 2.8 * 1.9 * 0.7in Weight: 33g Voltage adjustment method: In normal state (digital tube flash) Start key can increase voltage. The stop key can reduce tension. Set start voltage: In the common state of normal voltage display, press start key, display the charging start value voltage. Long press the start key until the digital tube flashes. Set the charging start voltage value by pressing the start key and stop key. Set the shutdown voltage: In the common state of normal voltage display, press the shutdown key, display the charging shutdown voltage. < br /> Long press the stop key until the digital tube flashes. Set the charging stop voltage value by pressing the start key and stop key. Reset: In the common power-on state, press the start key and stop key at the same time, 888 tube digital display, the reset is completed successfully. Settings: When the start value cannot be added, please adjust the stop value. QA: Question: How many voltages are the batteries suitable for? Answer: This module is suitable for 6-60V voltage range, supports 48V batteries at most. Because the voltage of 48V batteries is around 60V when fully charged. The module will be burned if the voltage is higher than this. Question: Why is the module not displayed after connecting the charger? Answer: Because the module may display when powered by battery, not display when the voltage is lower than 6V. Question: The starting voltage is so low or the stopping voltage is high. Answer: Because the limit start value is less than the stop value. If you want to adjust the start value, you must first adjust the stop value, vice versa. Question: The relay has a flapping noise. The digital tube or indicator light flashes. Answer: The charging current is too large or the battery capacity is too small. The voltage becomes the stop value when charging and makes the start value when circular discharging. The charger output voltage is higher than the shutdown voltage value. The voltage becomes the stop value when charging and the start value when circular discharging. If you don't believe, please set the shutdown voltage value above 60V, use the charger corresponding to the battery, and generally the charging current is 1/10 or 1.5/10. The charging voltage is 1.2 times that of the battery. Question: Which mode can control the automatic cycle load? Can it charge during use? Can the flow be limited? Answer: This is a voltage check. For example, set the start voltage 12V, stop voltage 14.4V. When the battery charges to 14.4V, it stops charging; when the battery decreases to 12V, it starts charging. It can be recharged during use. The module control mode is only closed and open, the module cannot limit the flow. The charging current depends entirely on the
