(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 flash 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
Default Settings
The default settings (not manually configured) for the UMS4 are:

* 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-off voltages. For the battery whose length is >60mm (2.4"), the UMS4
automatically identifies 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 effective to over-discharged
IMR batteries)
After entering the Charging Setting Mode:
Short press the C button to switch to different setting parameters (Charging Current and
Cut-Off Voltage).
Short press the V button to increase with a 100mA increment each time when setting
the Charging Current; or to switch to different battery types and voltage readings when
setting the Cut-Off 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:

increment each time. Long press the V button to directly access the maximum setting.
3. When the setting is finalized, long press the C button to save and exit the Charging
Setting Mode.
Note: When the input power is insufficient 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.
