Quick start
- Connect the M4 Pocket to a suitable DC 7.0-25.0V to power outlet.
- The display shows the boot logo for 2 seconds.
- After booting up, the screen enters the main interface as shown below:
- Short press [Voltage/Current] key to unlock the system and start adjusting parameters.
- Long press [Voltage/Current] key to set the charging cut-off voltage.
- Short press [Voltage/Current] key to select the charging current.
- When the output main port and the balance port voltage match, the M4 pocket will automatically start charging.
| Tips: Every time you turn on the charger, you need to press the button
once to unlock the system. This is a safety feature designed to prevent
incorrect selection of battery type and current.

Charging settings
After the power is turned on and the charger unlocked, the screen will display
the following.
Battery type setting
Long press [Voltage/Current] key to select battery cut-off voltage (battery
type), displayed as follows.
Different battery chemistries have different cutoff voltages. Please refer to the following table as reference, and verify with your battery manual:
4.20V | Lipo |
---|---|
4.35V | LiHv |
3.85V | Lipo-Storage |
3.60V | LiFe |
Important: |
- Ensure the correct battery type has been selected prior to charging. An incorrect choice may damage the battery and/or become a fire hazard. Please use caution.
- Do not use this product to charge non-compatible battery chemistries.

| Nomenclature:
- Lipo: Often referred to as a lithium polymer battery, a battery with a nominal voltage of 3.70V and 4.20V when fully charged.
- LiHV: Often referred to as a high-voltage lithium battery, a battery with a nominal voltage of 3.85V and 4.35V when fully charged.
- LiFe: Often referred to as an iron-lithium battery, a battery with a nominal voltage of 3.30V and 3.60V when fully charged.
- Lion: Often called a lithium-ion battery, a battery with a nominal voltage of 3.60V and 4.10V when fully charged.

Current setting
Short press [Voltage/Current] key to select the charging current, the current
can be selected from 4 values, 1.0A, 2.0A, 3.0A, 5.0A. 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, use 1.0A-2.0A for charging; This
effectively improves the cycle life of the battery. Always check the battery
manufacturers guidelines and charging instructions before charging.

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. Display as follows:
Display content description:
: Charging time.
: Input voltage.
: Charger temperature.
: The selected cell type cutoff voltage
: Other
cell cutoff voltages (not selected).
16.0V: Current battery voltage.
5.00A: Current charging current.
: Current limit sign.
: Power current limit,
: temperature limit,
: The battery or one of the cells is full.
888mAh: Accumulated capacity that has been charged.
4.000V: The first cell voltage, this cell is not balancing
4.001V: The second cell voltage, this cell is slowly balancing
4.002V: The third cell voltage, this cell is slowly balancing
4.005V: The fourth cell voltage, this cell is quickly balancing
| Tips: When charging a 1S battery, the battery voltage needs to be
provided to the balance port at the same time, so that the charger can
recognize and start charging.

Terminal voltage setting and manual calibration
Before connecting to the power supply, press and hold [Voltage/Current] key to
enter the calibration mode, as shown below:
Terminal volte: The terminal voltage after the battery is fully charged.
Accurate to +/- 10mV.
Calibration voltage: Battery calibration voltage, if the cell voltage
readings appear to be incorrect, use a high-quality voltage meter to measure
the actual voltage, then set this value to be the same as the meter.
DEFAULT: Restore to factory default.
