(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:
Battery Type and Capacity
Li-ion batteries
(4.2V±1% when fully charged)
Ni-MH/Ni-Cd batteries
(1.48V±1% when fully charged)
* 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:
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.
