User Notice Safety Notes
Please read the entire Manual completely before using, to make sure you can use this device properly andmore safely.
1. 4010DUO 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 byconnecting with CH-1 and CH-2 respectively.
2. 4010DUO 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.
3. Keep the charger away from children and pets at all times.
4. Never leave the charger unsupervised when charging or discharging. If you leave, disconnect the battery andswitch off charger to prevent any unexpected dangers or damage.
5. Ensure the charger program and settings match the battery pack otherwise the battery will be damaged and adangerous situation may arise, especially for Lithium batteries, which may cause a fire.
6. Do not mix batteries of different types, different capacities or from different manufacturers.
7. Do not disassemble the charger.
8. 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/Cmodel or inside a full-sized automobile.
9. Never block the air intake holes and never use in a refrigerated or high temperature environment. If used in suchan environment, the internal temperature protection may result in abnormal charging/discharging that could be
dangerous.
10. Do not allow water, moisture, metal wires or other conductive material into the charger.
11. Never charge or discharge any battery having evidence of leaking, expansion/swelling, damaged outer cover orcase, color-change or distortion.
12. Do not try to charge “non-rechargeable” dry cells.
13. Do not exceed the battery manufacturer’s suggested maximum charge rates.
14. Carefully follow the battery pack manufacturer’s recommendations and safety advice.

LiPo/LiIo/LiFe Battery Not Balance Charge Setup

When switch to Not Balance on Chg Mode, Only Chg End Current is available for charging end condition, and“” behind Chg Mod and Chg End Current are inactive.

Note: 1. The charger first charges with constant current (CC) according to the user setting, then turns toconstant voltage (CV) when the charging voltage reaches the peak point. In the CV phase thecurrent gradually falls, and the charger will terminate 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.

"

Balance Start : CV,CV-0.1V—1V,Alway
Default: CV-0.2
If the balance charge voltage is 4.2V, BalanceStart set to CV-0.2V; therefore the charger will
start to balance the battery cells when thevoltage reaches to 4.2V-0.2V=4V
Note: On Balance mode, the charger will monitor the voltage of individual cells to control it within the
Chg Cell Volt and equalize the voltage in all cells, to avoid some cell voltage over-charged or not
full. When selecting Balance mode, the balance port of charger or balance board must beconnected 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"" to return to the previous interface.
Balance Diff: 1mV-10mV; default: 5mVBalance Set Point: 1mV-50mV; default: 5mVBalance Over Charge: 0mV-50mV; default: 0mVBalance Done Delay: 0Min-20Min; default: 1Min

Note: If Balance Diff value is lower, the voltage difference between cells will be lower and thebalancing will take more time before the program ends. If Balance Set Point value is lower, thebattery will be closer to the setting cut-off voltage and the time taken will be longer before
the program ends. Balance Over Charge, the maximum overcharge compensation voltage acts
as accelerated charge, and the larger the value, the more obvious the accelerated charge.
For example: Charge Lipo with Vstd, set Balance Over charge to Vboc, the cell’s internal
Resistance detected is Ri, 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.
The value of Balance Done Delay is larger; the battery is closer to the setting cut-off voltage
when the program ends.

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

 Power Regenerative Mode
Note: 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 select To input mode.

 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.

 Resistance or Bulbs
1: Regenerative power
2: Regenerative voltage limit
3: Regenerative current limit
1

3
Resistance or bulbs as the load:
1. Connect the resistance or bulbs to any channel ofthe charger;
2. In another channel of the charger, MEMORYSETUP→ Discharge→ Regenerative Mode→ To
channel, to select Resistance or bulbs，then connect
the battery for discharging to this channel, and startthe discharge program to discharge the battery.
Press STOP/START button to end the program
during the period.

Battery as the load:
1. In any channel of the charger, MEMORYSETUP→ Discharge→ Regenerative Mode→ To
channel, to select Charging battery; then connect
the battery for discharging to this channel, and startthe discharge program，and this channel will be indischarging stand by status;
2. Connect the battery as the load to anotherchannel of the charger, and start the charge
program; the discharging channel is activatedaccordingly;
3. Press STOP/START button of any channel
during the program running process to end therunning 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)

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
Iset: Discharge current
Vbat: Battery voltage
For example: discharge a pack of 20V lithium battery at 7A
R = 20V / 7A = 2.85Ω
P = 20V X 7A = 140W
