Safety Notes
Please read the entire Manual completely before using, to make sure you can use this device properly and more
safely.
1308DUO 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 the
charger 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
connecting with CH-1 and CH-2 respectively.
2308DUO 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 in
extreme 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.
3Keep the charger away from children and pets at all times.
4Never 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.
5Ensure 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.
6Do not mix batteries of different types, different capacities or from different manufacturers.
7Do not disassemble the charger.
8Do 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 or
inside a full-sized automobile.
9Never block the air intake holes and never use in a refrigerated or high temperature environment. If used in such an
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 or case,
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.

308DUO Special Features
1The 308DUO uses advanced Synchronous buck-boost DC/DC converter technology, high power, a high current and
high-performance power conversion circuit. The maximum charge power capacity is up to 1300W, the maximum
charge/discharge current of a channel is up to 30A, and two channels in Synchronous Mode are up to 50A.
2Each channel supports 8s LiPo, Lilo, LiFe and NiZn batteries, with maximum 1.2A balance current, and adopts a
unique balance calculation of internal resistance correction. Supports 1-20s NiMH/NiCd batteries and 1-15s Pb
batteries.
3With 1A/5V USB charging port, convenient for the user to charge mobile phones and PCs.
4When the channel output connects the battery after the charger powers on, it will start automatically the
anti-sparking protection.
5Intelligent fan control. Sensing internal temperature via the internal temperature sensor, to thereby control the fan
speed.
6Internal temperature protection. When the internal temperature exceeds the Power Reduce temperature, the output
power is automatically reduced; and the charger will shut down when temperature exceeds the Shut-down
temperature.
7This charger can save 64 parameters sets and support the data import/export to SD card.
8A 2.8-inch LCD screen provides rich information including current, voltage, power, capacity, internal resistance,
control status, time-consuming and temperature, etc.
9Multi-discharge features: self-discharge, regenerative to input discharge, and lithium battery extra expanding
discharge.
10 Supports measurement for internal resistance of battery offline and online. Can measure not only the internal
resistance of the entire battery pack, but also measure the internal resistance of each cell within the lithium battery.
11 The iCharger has protection for reversed polarity (input or output), input voltage/current, battery temperature,
charging capacity, overrun time and maximum power etc.
12 Supports upgrading the hardware program by USB port or SD card. The iCharger also supports the “Logview”
software and can display, plot and analyze the charge and discharge data by it. (See detailed information about
Logview at the following website: http://www.logview.info)

The Order of Connection for Charger
The Power Input Ground Cannot be Connected with the Output Ground
The Order of Connection
Please be sure to connect the input power first, after the charger starts the output anti-sparking protection (after
electrifying 1 second), and then connect the battery.
Dual-channel Connection Notes
Connection for Channel Asynchronous Mode
ChannelAsynchronous Mode: i.e. CH-1 and CH-2 work independently.
Go to MEMORY SETUP→Option→Channel Mode to select Asynchronous.
Note: In this mode, the two channels must not have any external electrical connection; otherwise it will
damage the charger. You cannot charge with connection as shown in the left picture, the correct
connection as shown in the right picture.
Note: The input of power lead cannot be
connected directly to the output (see left
picture), and the voltage of the input power
supply cannot have large instantaneous
fluctuations, otherwise the charger will be
damaged.
