Dual Balance Charger/Discharger/DC Power

User NoticeSafety Notes
Please read the entire Manual completely before using, to make sure you can use this device properly and more safely.

456DUO is a dual port charger, but this does not mean you can charge/discharge any
configuration of the two sets of batteries! You must follow these rules: two battery packs
without any external electrical connections, otherwise they could permanently damage thecharger or batteries. For example: when charging a 12-cell battery pack, you must split it into
two separate 6-cell, and you must never charge two 6-cell battery packs in series by connectingwith CH-1 and CH-2 respectively.
456DUO input power cannot have fast voltage/current fluctuations, which may cause output
over current, and will damage the charger and/or the batteries and input power source inextreme cases. For example: setting the input protection current and voltage is necessary
according to the specifications of the input power supply, in order not to cause power overload.
Some power supply overload protection circuits will produce substantial fluctuations in the
supply voltage.

Keep the charger away from children and pets at all times.
Never leave the charger unsupervised when charging or discharging. If you leave, disconnect the battery and switch off

charger to prevent any unexpected dangers or damage.
3 Ensure the charger program and settings match the battery pack otherwise the battery will be damaged and a dangerous
situation may arise, especially for Lithium batteries, which may cause a fire.
4 Do not mix batteries of different types, different capacities or from different manufacturers.
5 Do not disassemble the charger.
6 Do not place the charger or any battery on a flammable surface or near a combustible material while in use. Do not
charge or discharge on a carpet, cluttered workbench, paper, plastic, vinyl, leather or wood, inside an R/C model orinside a full-sized automobile.
7 Never block the air intake holes and never use in a refrigerated or high temperature environment. If used in such anenvironment, the internal temperature protection may result in abnormal charging/discharging that could be dangerous.
8 Do not allow water, moisture, metal wires or other conductive material into the charger.
9 Never charge or discharge any battery having evidence of leaking, expansion/swelling, damaged outer cover or case,color-change or distortion.
10 Do not try to charge “non-rechargeable” dry cells.
11 Do not exceed the battery manufacturer’s suggested maximum charge rates.
12 Carefully follow the battery pack manufacturer’s recommendations and safety advice.

456DUO

Dual Balance Charger/Discharger/DC PowerThe charger first charges with constant current (CC) according to the user setting, then turns to constant voltage (CV)when the charging voltage reaches the peak point. In the CV phase the current gradually falls, and the charger willterminate charging when the current falls below the percentage of the configured charge current.
For example: the default value of Chg Current is 2A, and the default value of Chg End Current is 10%
Chg End Current=2A*10%=0.2A
Therefore it stops charging when the charging current reduces to 0.2A.
LiPo/LiIo/LiFe/LiHV/LTO/NiZn/User Balance Charge Setup
Switch to Slow Balance, Normal Balance, Fast Balance or User Balance on Chg Mode as the balance charge mode, and" Set …" button will be available, click it to enter Balance mode setup interface.
Balance Start : CV,CV-0.1V—1V,Alway
Default: CV-0.2
If the balance charge voltage is 4.2V, Balance Start
set to CV-0.2V; therefore the charger will start tobalance the battery cells when the voltage reaches to
4.2V-0.2V=4V
On Balance mode, the charger will monitor the voltage of individual cells to control it within the Chg Cell Volt andequalize the voltage in all cells, to avoid some cell voltage over-charged or not full. When selecting Balance mode, thebalance port of charger or balance board must be connected with battery except for connecting 1S battery.
When switch to User Balance mode on Chg Mode; the Balance Diff, Balance Set Point, Balance Over Charge andBalance Done Delay are available, after setting, click "Back" to return to the previous interface.
Balance Diff:
Balance Set Point:
Balance Over Charge:

1mV-10mV; default:5mV
1mV-50mV; default:5mV
0mV-50mV; default:0mV

Balance Done Delay:

0Min-20Min; default:1Min

If Balance Diff value is lower, the voltage difference between individual cells will be lower and the balancing will takemore time before the program ends.
If Balance Set Point value is lower, the battery will be closer to the setting cut-off voltage and the time taken will belonger before the program ends.
Balance Over Charge, the maximum overcharge compensation voltage acts as accelerated charge, and the larger thevalue, the more obvious the accelerated charge.
For example: Charge Lipo with Vstd, set Balance Over charge to Vboc, the cell’s internal Resistance detected isRi, when the charge current is Ia, the actual CV value of cells is Va
IF Ri*Ia > Vboc THEN
Va = Vstd + Vboc
ELSE
Va = Vstd+Ri*Ia
Please set this parameter after understanding fully, or keep the default value at 0.

Important Notes
The Charging Principle for Reflex Charge Mode
Reflex charge mode only supports NiMH and Pb battery. It
does not support lithium battery. Using reflex charge mode
to charge battery can reduce effectively the heating of thebattery. Go to the MEMORY SETUP → Charge → Chg
Mode to select Reflex mode.

Power Regenerative Mode
which is when the power supply for the charger acts as"battery power", the charger will regenerative charge for"battery power" during the process to discharge the battery.
Go to MEMORYSETUP→Discharge→Regenerative Mode
→ To input.

Channel Regenerative Mode
Channel Regenerative Mode is the feature for discharging from one channel to another channel, which supports resistor
discharge, bulbs discharge, and charging battery.

1: Regenerative power
2: Regenerative voltage limit
3: Regenerative current limit

program，and this channel will be in discharging standby status;
2. Connect the battery as the load to another channel ofthe charger, and start the charge program; thedischarging channel is activated accordingly;
3. Press STOP/START button of any channel during the
program running process to end the running status.

Lithium Battery Extra Discharge Mode
You can expand the iCharger’s discharge power capacity by connecting the external capacity resistance. You should pay
special attention when expanding the discharge circuit. The balance port must be connected to the battery and the expanding
capacity resistance R should be connected in series to the positive connection. (See the following diagram)
OutputiChargerR+- Lixx Batt.

Pack

Bal. port

In this mode, the lithium battery discharges through the iCharger and R, P = Pi + Pr, (Pi is the charger’s wasted power
capacity; Pr is wasted power capacity by resistance). Pi is limited by the set charger’s maximum discharge power capacity.
External capacity resistance’s setting:
R = Vbat / Iset;
P = Vbat * Iset;
R: The value of the external capacity resistance
P: Rating capacity of the external capacity resistance
Vbat: Battery voltage
Iset: Discharge current
For example: discharge a pack of 20V lithium battery at 7A
R = 20V / 7A = 2.85Ω
P = 20V X 7A = 140W
