(English) UMS4 User Manual

Operating Instructions

Connect to power source: connect the UMS4 to an external power source (a USB adapter, a computer or other

USB charging devices) via the USB charging cable.

Insert batteries: The UMS4 features 4 independently controlled charging slots. Insert batteries of supported types

into each slot according to the polarity marks on the slot. After battery installation, the UMS4 begins charging and

presents Battery Health by “Good” or “Poor”, Internal Resistance, Charging Current, Battery Voltage, Charged Volume

and Charging Time on the LCD screen.

Battery Inspection and Error Report: The UMS4 has reverse polarity protection and anti-short circuit function. If

there are batteries inserted with polar reversed or short-circuited, the LCD screen of relevant slot will indicate “EE EE”

and the power level display will ash to notify the user of an error.

Smart charging: The UMS4 can choose appropriate charging currents based on intelligent detection about battery

types and capacities. Manual charging current selection is also available. The UMS4 is compatible with:

1) 3.6V/3.7V Li-ion rechargeable batteries

2) 3.8V Li-ion rechargeable batteries (4.35V±1% when fully charged)

3) 1.2V Ni-MH/Ni-Cd rechargeable batteries

4) 3.2V LiFePO4 batteries

* When charging 1 or 2 batteries, it is recommended to put them into Slot 1 and Slot 3, or into Slot 2 and Slot 4, to

achieve a higher default charging current of 2,000mA. Otherwise the default charging current is 1,000mA.

** When charging 1 or 2 batteries, it is recommended to put them into Slot 1 and Slot 3, or into Slot 2 and Slot 4,

to achieve a wider selectable range of charging current of 300mA-3,000mA. Otherwise the selectable range of

charging current is 300mA-2,000mA.

Note: The UMS4 can automatically select charging modes for Ni-MH/Ni-Cd batteries and 3.7V Li-ion batteries.

LiFePO4 batteries and 3.8V Li-ion batteries require manual settings on charging cut-o voltages. For the battery

whose length is >60mm (2.4”), the UMS4 automatically identies its capacity as >1,200mAh.

Button Operations

During the charging process:

Short press the C button to cycle through the charging status of the 4 slots.

Short press the V button to cycle through Battery Health, Internal Resistance, Charging Current, Battery Voltage,

Charged Volume and Charging time on the LCD screen.

Long press the C button to enter the Charging Setting Mode.

Long press the V button to enter Restoration Mode. (Only eective to over-discharged IMR batteries)

After entering the Charging Setting Mode:

Short press the C button to switch to dierent setting parameters (Charging Current and Cut-O Voltage).

Short press the V button to increase with a 100mA increment each time when setting the Charging Current; or to

switch to dierent battery types and voltage readings when setting the Cut-O Voltage.

Long press the V button to directly access the maximum setting when setting the Charging Current.

Long press the C button to save and exit the Charging Setting Mode.

Note: Perform no action in 10 seconds to exit the Charging Setting Mode without saving and return to the previous

settings.

Charging Voltage Settings

The UMS4 is compatible with 3.6V/3.7V Li-ion and Ni-MH/Ni-Cd batteries with automatic detection and adoption of the

suitable charging voltage. For LiFePO4 batteries and 3.8V Li-ion batteries, please follow the steps below for charging

voltage settings:

1. After the battery is inserted and the charging process begins, short press the C button to select the correct slot

and long press the C button to enter Charging Setting Mode.

2. After entering Charging Setting Mode, short press the C button. When the screen shows the ashing text “CHG.

MODE”, short press the V button to select the correct charging voltage (3.7V/4.2V/4.3V).

3. For LiFePO4 batteries, the voltage needs to be set to 3.7V. For 3.8V Li-ion batteries, the voltage needs to be set to

4.3V.

4. When the setting is nalized, long press the C button to save and exit the Charging Setting Mode.

Charging Current Settings

Please follow the steps below for charging current settings:

1. After the battery is inserted and the charging process begins, short press the C button to select the correct slot

and long press the C button to enter Charging Setting Mode.

2. After entering Charging Setting Mode, the screen will show the ashing text “CHG. STATUS”. Short press the V

button to increase the charging current with a 100mA increment each time. Long press the V button to directly

access the maximum setting.

3. When the setting is nalized, long press the C button to save and exit the Charging Setting Mode.

Note: When the input power is insucient and a large charging current is set, the charger will automatically adopt

the intelligent current distribution according to the input power.

QC Charging Mode

The UMS4 is QC 2.0 input available. When the charger is powered by a QC supportive device or connected to a QC

adapter, the screen will show “Quick Charge” and the single slot max output will achieve 3,000mA.

Automatic Battery Internal Resistance Detection

When the UMS4 is on and the battery is installed, it will automatically detect and display the Internal Resistance

below the “CHG. STATUS”. When the Internal Resistance is below 250mΩ, it will show “Good” on the screen. When it

is above 250mΩ, it will show “Poor” on the screen to indicate that the battery should be replaced.

Charged Volume Calculation

During the charging process, the system will automatically calculate and display the Charged Volume below the “CHG.

STATUS”.

Anti-short Circuiting and Reverse Polarity Protection

If there are batteries inserted with polar reversed or short-circuited, the screen will ash to show “EE EE”.

Energy Saving Function

If there is no action to the buttons or batteries in 3 minutes, the screen will automatically go dim to save energy.

Perform any action to light up the screen.

Over-Discharged Li-ion Battery Activation

The UMS4 is capable of activating over-discharged Li-ion batteries with a protective circuit. After battery installation,

UMS4 will test and activate the battery before charging. When a battery is detected as damaged, the screen will show

“EE EE”.

Over-Discharged IMR Battery Restoration

When an over-discharged IMR battery is inserted, the screen will show “EE EE”. In this case, long press the V button

to enter Restoration Mode. After that, the charging process will continue. The battery should be replaced if it fails to

be restored after several attempts.

NOTE: When attempting to restore an IMR battery, reverse polarity protection is temporarily disabled. Please ensure

batteries are correctly inserted. Failing to do so may result in re or explosion.

Overtime Charging Protection

The UMS4 will separately calculate the charging time of each battery. When the charging time exceeds 20 hours in

one slot, it will automatically cease the charging process of this slot and display “END” below the “CHG. STATUS”. This

is to prevent possible overheat or even explosion due to battery quality issue.

Precautions

1. The charger is restricted to charging Li-ion, IMR, LiFePO4, Ni-MH/Ni-Cd rechargeable batteries only. DO NOT use

the charger with other types of batteries as this could result in battery explosion, cracking or leaking, causing

property damage and/or personal injury.

2. Moderate heat from this product is to be expected during the charging process, which is normal.

3. Ambient Temperature of Usage: -10~40℃ (14~104℉); Temperature of Storage: -20~60℃ (-4~140℉)
