This pro charger is designed for applications that demand adaptive charging
for Lithium（Lit）and LiFePO4 (LFP) batteries. Battery with or without load can be
connected to the charger all the time and the charger will keep on monitoring
the battery. It has Battery over temperature or low temperature protection
function when connected the supplied battery temperature sensor.
Control & Indicators
1. 3 digit LED. Displays voltage, current,
operation and fault code. No operation for 3
minutes, the LED turn off, press the button
to restore the display.
2. LED indicates Voltage (V) and Current (A).
3. Battery Icon is on when Charger is set at
the charger mode.
a. Soft-start/ Bulk charging: Charger
Icon indicator light flashing fast
b. Absorption/EQ charging: Charger
Icon indicator light flashes slowly
c. Float charging: Charger Icon indicator
light always on
d. When in DC mode, the charge Icon
indicator light remains off.

Using the charger
After checking for the correct ac voltage on the rating label and connection to AC supply,
3 digits LED scroll displaying the voltage and current after displaying the version
The default battery type Lithium is on showing charger is in good working condition.
Press and hold the SET button until the 3 digits LED display flashing, the charger now
goes into the setting MENU.
Remark: The charger will back to the normal operation automatically after 30 seconds in
case no further action or selection. Any selection without confirmation will not save into
the charger.
1. Battery Type and DC source Selection Procedure:
In the setting menu, the display shows “Lit” that means the battery types and DC source
selection mode. Each short press will change the mode and battery type in cyclic order.
Lit→LFP→DCS→Lit→….
Just stop at your desired battery type or DCS, press and hold the SET button for 3
seconds to next setting mode.
2.1 In case the battery type (Lit or LFP) is selected, you can set the Float charge
ON/OFF
Press and hold the SET button until display “Lit” or “LFP” NOT flashing, the display
will show “FLT”. Short press the SET button will change the “ON” and “OFF” in
cyclic order ON→OFF→ON→… Just stop at your desired selection, press and
hold the SET button until the display not flashing and then goes to the next setting
mode.
2.2 In case “dCS” is selected, you can set the output voltage
Press and hold the SET button until display “dCS” not flashing, the display will
show the voltage value.
a. The first step is to set the unit digit of output voltage value. While unit digit
flashes press SET button to change by 1V Steps: 12.8→13.8→14.8→12.8.
b. Press and hold the SET button to confirm the unit digit value and enter into
decimal value setting of 0.1V steps.
c. Press SET button to change by 0.1V steps.
13.0→13.1→13.2→13.3→13.4→13.5→13.6→13.7→13.8→13.9→13.0→…
Press and hold the SET button to confirm and then goes to the next setting
mode the charging current.
3. Charging current setting
The display will show the current setting. Short press the SET button can change the
charging current value in cyclic order. 40→4→10→20→40→…
Just stop at your desired value, press and hold the SET button until the set value not
flashing.
All settings completed and the charger will back to the normal operation
automatically.
WiFi setting (WiFi/ Bluetooth version only)
Bluetooth is available to be connect in factory default. Use Smartphone app from
AppStore or Google play to connect charger using Bluetooth first. The charger
Bluetooth name is start with “mbt”. After connected with Bluetooth, it can configure WiFi
connection within apps.

Battery Charger installation and Connection
Before connecting or disconnecting the charging cable, unplug AC cord from the mains.
First connect the Red cable to Positive + terminal of charger and the battery Positive +
Pole.
Then connect the Black cable to the Negative – terminal and the Negative – Pole of the
battery. Make sure all the connections are secured and well tighten up, double check on
the correct polarity.
After AC is on, check for the correct battery type, if not you can always change to desire
battery type by quick short presses without disconnection of the AC mains or battery.
Dual bank charging
The two batteries must be of same chemical make up and type to avoid over and under
charging because only one setting of charging profile for both.
Two batteries are charged simultaneously and the battery with the lowest level gets
most share of the current in the Bulk charge stage until it is up to the sane voltage level
of the second battery (battery with higher initial level).
Both batteries will go to the Absorption and the Float charge at the same time.
P.5

LiFePO4 (LFP) battery
Caution: Never charge LFP battery when its temperature is below 0°C.
There is a special charge algorithm and treatment for Lithium FePO4 (LFP)
batteries to ensure safe and optimal charging adaptive to the special chemistry
of the battery which is quite different to Lead Acid battery. There are only two
active charging stages namely Bulk and inactive (no charging current) Standby
Stage.
DC Source
Charger can be used as a constant 12.0-15.0V (LBC-9220: 24.0-30.0V) DC
source with start upload limited to 2AMP and subsequent maximum continuous
28Amp (LBC-6220:14Amp) load without the battery.
Battery with load
A load can be connected to the battery during charging as long as the load is
not larger than the rated output of the charger. The maximum continuous load
should be less than 28Amp (LBC-6220:14Amp).
Supplied Accessories
Battery temperature sensor for battery low temperature protection and battery
over temperature protection.

Protection
Over Temperature Protection of battery
When this sensor detects the temperature of battery over 60ºC, the charger will
decrease the charging current to 1Amp and LED display “F02”. When the
battery temperature reduce back to 60 ºC.
Over Temperature Protection of charger:
At high operating temperature charger will gradually decreases the output
power to protect the electronic components from further thermal stress and at
the same time keeps a safe and continuous charging. The charger will
decrease output current in 3 levels, while the charger temperature keeps on
increasing, it will decrease output current to 30Amp first, then 20Amp and
finally 1Amp. And LED display “F01”.
Short circuit protection by constant current method and auto reset when fault is
clear.
Reversed polarity protection with 25Amp x2 (LBC-6140)/ 25Amp (LBC-6220)
thermal fuse.
