Quick start 1，Connect the M4AC to a suitable 100-240V AC to power outlet. 2，The display shows the boot logo and stays for 2 seconds. 3，After booting up, the screen enters the main interface as shown below: 4，Short press [Type/Current] key to release the locked state. 5，Long press [Type/Current] key to select the cut-off voltage to be charged. 6，Short press [Type/Current] key to select the current to be charged.
================================= Tips: Every time you turn on the charger, you need to press the button once to release the lock. This safety feature is to prevent incorrect selection of battery type and current.
Charging settings After the power is turned connected and the charger unlocked, the screen will display the following. 1，Battery type setting Long press [Type/Current] key to select battery cut-off voltage (battery type), the display is as follows.
battery types. The following table: 4.20V Lipo 4.35V LiHv 3.85V Lipo-Stroage 3.60V LiFe ================================= Important: 1, Choosing the wrong battery type to charge may damage the battery, the charger, and cause fire hazards. Please choose carefully. 2, Please do not use this product to charge the battery that is not marked with the battery type.
2，Current setting Short press [Type/Current] key to select the charging current, the current can be selected from 4 levels of values, 0.5A, 1.0A, 2.0A, 2.5A. The display is as follows. ================================= Tips: When selecting the current, it is recommended to use a charging rate of 1C-2C. For example: 1000mAh battery, it is recommended to use 1.0A-2.0A for charging, which will effectively improve the cycle life of the battery.
Start charging After setting the battery voltage and current, connect the battery. After the charger detects that the voltage between the main port and the balance port matches, it will automatically start charging.
