QUICK START
1. Turn on the charger by connecting a 7-30V power source to the input port on the
back of the Turnigy M8.
2. The Display will show bootup and is ready to operate within 2 seconds.
3. Once the bootup is complete the main interface will show as below.
4. Operate by rotating the Shuttle button, move the cursor to select the function, press
the Shuttle to enter the selected function and enter the corresponding interface.
5. After entering the function interface, rotate the Shuttle to move the cursor, press the
Shuttle again to modify the options or values. After the modification is complete
press the Shuttle button once more for confirmation.
Select [Charge] function on the main interface, press [Shuttle button] to enter the charging
function, the following interface is displayed as below.
CHARGE AND DISCHARGE
7

1. Battery type setting
Rotate the Shuttle button, move the cursor to select the battery that has been set, or
create a new battery profile,both by pressing [Shuttle key] to enter the battery setting
interface, as shown below.
8

Move the shuttle to desiredbattery type. The charger supports the charging and
discharging of 5 types of batteries: Lipo, LiHV, LiFe, NiMh, PB. After selecting the desired
battery settings that matches the actual battery give the [Shuttle button] a short press for
Confirmation and [Exit] if you want to return to previous menu..
1. Incorrect battery type charging may damage the battery or
charger, and may lead risks of unexpected dangers or damage.
2. Batteries that cannot be found in the menu then pleasedo not
use this product to charge them.
3. PB: often referred to as lead-acid battery, nominal voltage
2.00V.
2. Cutoff voltage setting（TVC）
Terminal Voltage Control (TVL) can be adjusted by moving the cursor to [4.200V] and
press [Shuttle] to modify the cut-off voltage. Adjust the value and step 1mV by
rotating the shuttle button.
Important:
9

1. Only LiPo, LiHV, LiFe battery can be set for cutoff voltage
2. Do not modify the cutoff voltage when you are unfamiliar with
battery characteristics.
3. The cutoff voltage can be set to the range of positive and
negative 50mV of full voltage.
3. NiMH Setting（PeakV）
When the battery type is NiMh, you can set the negative internal pressure value when
the battery is full, and the range can be set from 5mV to 20mV, as shown below.
Tips：
1. Only NiMh battery can set the battery negative internal pressure
value
10

4. Battery Setting
Move the cursor to the [Auto] or [1 - 8S] by pressing the [Shuttle] and rotate to change
the number of battery cells. When set to [Auto], the charger will automatically
recognize the number of connected batteries according to the voltage of battery which
is connected to the output port or Balance Port.
Tips：
1. Batteries which are over-discharged may cause the number of
cells to be falsely recognized, you need to manually set the
correct number of cells or by connect to the balances port.
2. If the number of cells is set incorrectly the battery may be
overcharged and damaged, please set it carefully.

5.Current setting
Move the cursor to the charging current position and press [Shuttle] to modify the
charging current values. Turn [Shuttle] to adjust the value.
Move the cursor to the discharge current position and press [Shuttle] to modify the discharge
current. Turn [Shuttle] to adjust the value. The charger supports 2 discharge modes.
1. Discharge mode, through internal heat dissipation discharge, maximum support up to
3.0A@20W discharge.
2. Recovery Discharge mode, if the input is battery power, this function will recover
electrical energy back to the input battery, the maximum support 15.0A@300W
discharge

Tips:
1. Please set the charging rate according to the battery capacity.
For example, if the battery capacity is 2000mAh, please set the
charging current to 2.0-4.0A.
2. Charging and discharging current is only valid in the
corresponding working mode.
3. Discharge mode setting, please refer to the <System Settings> .
6.Charging modes
Move the cursor to STR [Store] DSC [Discharge] CHG [Charge] position, press
[Shuttle], the charger will work on the basis of the mode you have selected. It will
indicate the target voltage that will charge the battery. As shown below ;

14
When selected as DSC [Discharge], it will prompt the target voltage to the battery. If
Recovery Discharge Mode, it is also necessary to set the cutoff voltage of the power battery.
As shown below;

When selected as STR [Storage], it will prompt the target voltage to charge and discharge
the battery. If Discharge Recovery Mode it is also necessary to set the cutoff voltage of the
battery. As shown below;
Tips:
1. The discharge cutoff voltage should be set according to the
discharge characteristics of the battery from the manufacturer.
2. If the recovery limit voltage is set to the highest protection
voltage of the power supply, the charger will automatically stop
the recovery discharge. Setting too high might overvoltage and
damage the input power.
15

Rotate [Shuttle] on this screen to switch the bottom status display information or press and
hold [Shuttle Button] for 2 seconds to dynamically set the working current. As shown below

2. Operation Modes : Current limit flag. P: power, C: maximum current I: input over
current or Powe A: activate charging
3. Charge or discharge power of the charger
4. Internal temperature of the charger5
5. Operation time since started. Unit: minute: second
6. Capacity that has been charged or discharged
7. Currently set battery type and number of Cells
8. Current operating current set. Long press to modify.

To end the charge and discharge operations, press [Exit], pop-up prompt box, press [Shuttle]
to terminate the operation.
When charging is complete, or charging ecountersErrors. Apop-up window is displayed and
a warning sound will be heard.As shown below;

1. Charging or discharging, should be under supervision
throughout the process.
2. When charging and discharging the lithium battery, if you only
connect the output port, battery will not be balanced. Connect
the battery with balance port, the balance management will
automatically perform.
3. When charging is completed, unplug the battery, if you plug a
new battery, it will automatically continue to charge and
discharge according to the current setting. please pay attention
to whether the number of detected cells matches the actual
ones.
