## Description

Battery charging control module with display, works as a relay that starts and stops charging according to set thresholds, ideal for maintaining batteries during long periods of non-use. Supports 6-50VDC power supply, current up to 30A, fine adjustment with 0.1V step for start and stop, displays battery voltage in real time and is quickly set from the buttons.
Battery charging module 6-60VDC, HX-M604, with display. The module acts as a relay that allows or not to charge the battery depending on the set values.
It can be used to store batteries during the winter, when they tend to discharge.
Specifications:
Supply voltage: 6 - 60VDC
Display accuracy: 0.1V
Control accuracy: 0.1V
Output type: direct
Compatible batteries: 6-60VDC, maximum 80VDC
Dimensions mm: 81 x 54 x 18mm
Instructions:
A battery between 6 and 60V is connected (it will not light up without a battery).
A charging source between 6 and 60V is connected.
The module cannot be used as a power source (only works together with a battery)
The discharge threshold is set (the voltage at which the module will start charging the battery)
The charging threshold is set (the voltage at which the module will finish charging the battery)
Setting the starting voltage: in the state of displaying the battery voltage, pressing the "START" button will display the starting voltage; press for 3 seconds, the display will flash; use the START and STOP buttons to set the load start voltage.
Stop voltage setting: in the battery voltage display state, pressing the "STOP" button will display the charging stop voltage; press for 3 seconds, the display will flash; use the START and STOP buttons to set the load stop voltage.
Reset: while the module is on, press START and STOP at the same time until the display shows "888". The module will be reset to factory settings.
