User Notice
Safety Notes
Please read the entire Manual completely before using, to make sure you can use this device properly and more safely.
DX8 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.
DX8 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.
1Keep the charger away from children and pets at all times.
2Never 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.
3Ensure 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.
4Do not mix batteries of different types, different capacities or from different manufacturers.
5Do not disassemble the charger.
6Do 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.
7Never 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.
8Do not allow water, moisture, metal wires or other conductive material into the charger.
9Never 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.

The 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 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.
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.
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 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 and
Balance Done Delay are available, after setting, click "Back" to return to the previous interface.
If Balance Diff value is lower, the voltage difference between individual cells will be lower and the balancing will take
more 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 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.
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 to
balance the battery cells when the voltage reaches to
4.2V-0.2V=4V
Balance Diff: 1mV-10mV; default:5mV
Balance Set Point: 1mV-50mV; default:5mV
Balance Over Charge: 0mV-50mV; default:0mV
Balance Done Delay: 0Min-20Min; default:1Min
