## Description

Charge control module for 12-24V batteries, functions as a smart relay that automatically starts and stops charging between set thresholds, has a display for displaying voltage and simple adjustment using buttons, accepts DC 10-30V power supply and includes LM2596 regulator, ideal for maintaining car, motorcycle or solar panel batteries.
Battery charging module 12-24V XH M603, with display and protection. The module acts as a relay that allows or prevents battery charging.
Specifications:
Power supply voltage: 10 - 30VDC
Voltage regulator: LM2596
Output type: Direct
Instructions:
Connect a 12 or 24V battery (the module will not turn on without a battery).
Connect a charging source between 10 and 30V.
The module cannot be used as a power supply (it only works together with a battery).
Set the discharge threshold (the voltage at which the module will start charging the battery).
Set the charging threshold (the voltage at which the module will stop charging the battery).
Start voltage setting: when displaying the battery voltage, pressing the "START" button will show the start voltage; press for 3 seconds, the display will flash; use the START and STOP buttons to set the start voltage for charging.
Stop voltage setting: when displaying the battery voltage, pressing the "STOP" button will show the stop voltage for charging; press for 3 seconds, the display will flash; use the START and STOP buttons to set the stop voltage for charging.
Reset: while the module is on, press START and STOP simultaneously until the display shows "888". The module will be reset to factory settings.
Practical example:
Keeping a motorcycle battery charged during the winter.
Charging the battery using solar panels.
Batteries: 12-24V Lead-acid, nickel-cadmium, nickel-metal hydride, lithium-ion, polymer, car batteries.
WARNING: DO NOT POWER DIRECTLY FROM 220VAC OUTLET! POWER WITH DC CURRENT BETWEEN 10 AND 30V.
The module ONLY works when connected to a battery (a "dead" battery will not start the module, so these cannot be used).
