Warnings and Safety Tips

The following safety tips are essentially important. Please strictly follow the manual’s instruc-

tions in operation to guarantee safety. Improper operation or incorrect working parameter

settings may cause damages to the charger and battery and/or result to a re.

Do not use the charger in an unattended manner; in case of any functional abnormity, please
stop using it and refer to the manual.

Keep the charger away from dust, humidity, rain and high temperature, as well as avoid direct
exposure to the sun and intense vibration.

Charger power input for the DC T6 / T6 Lite (8-32V), T8 (12-40V),make sure the polarities are
correct when connecting to the power supply.

Please place the charger on a heat-resisting, non-ammable and insulating surface. Do not
use it by placing it on the car’s seats, carpet or other similar places. Keep inammable and
explosive objects away from operation areas of the charger.

Make sure the heat emission hole at the bottom of the charger is uncovered while in use, and
ensure the cooling fan smoothly extracts heat.

Please fully understand the charging and discharging characteristics as well as the battery’s
specications. Additionally, set up proper charging parameters in the charger. Incorrect
setting of parameters can cause damage to the charger and battery and/or result to
disastrous consequences such as re or explosion.

When charging or discharging is completed, please press the speed shuttle key to terminate
current task, and remove the battery when the charger shows the standby screen.

How to Conrm Charging Current

It is very important to know the maximum charging current of the battery as excessive current

could influence the life span of battery and/or cause damages. In addition, excessive current

can cause heating and/or explosion of the battery during the charging process.

The charging and discharging capacity of battery is usually marked with C value. Multiplying the

charging C value and battery capacity equals to the maximum charging current supported by

the battery. For example, for a 1000 mAh battery with a charging capacity of 5C, the maximum

charging current would be 1000*5=5000mA; therefore, the maximum charging current is 5A.

For a lithium battery, if it is impossible to confirm the supported charging C value, please set the

charging current below 1C for the sake of its (lithium battery) safety.

The reference relation between C value and charging time: charging time ≥60 minutes/

charging C value (it therefore needs around 60~70 minutes to complete charging with 1C). Due

to differences in battery conversion ef ficiency, the period to complete the charging might be

extended.

T series charger will charge battery in series, make sure output port is connected. For lithium battery, in

order to detect each cell's voltage and make sure battery is well balanced, we strongly suggest user to

connect balance port to do balance charging. When try to do unbalanced charging, before starting charger

will give you warning.

Storage function

While Select storage function, if battery voltage is lower than storage voltage, charger will

perform charging task. If battery voltage is higher than storage voltage , charger will perform

discharging function. While in charging and discharging, to save task time, charger will not do

precise balancing.

When task nishes, there might be dierence between setting voltage and real voltage. This is

totally normal.

Task Setting

Over-discharging battery reactivate and repair function

Over-discharging battery reactivate and repair function

After charging task initiates, if battery voltage is lower than pre-charging voltage, charger will

charge battery at 0.1A to reactivate and repair. After battery voltage is higher than pre-charging

voltage, charger will charge battery as setting. This procedure can protect over-discharging

battery then reactivate and repair

Resistance detection

Charger support resistance detection. This function can only be used while charger is doing

balancing charging. After initiating charging task in 2~3 minutes, charger can measure cell

resistance. In dierent battery capacity, battery resistance is dierent. Generally speaking, higher

the remaining capacity is, resistance is lower.

During resistance measurement, charger will adjust instantaneous current. So during charging if

you nd any sudden change of current, this is normal.

This value of resistance is not as precise as professional resistance meter. Resistance is only used

for comparison for each cell. Also charging current inuence resistance accuracy.

Charging process complete.

During charing process, screen displays orange, after charging completion screen will change to

green or blue. After charging completion, voltage dierence between each cell is less than

20mV, screen will turn to green. If you are in hurry, it's good to stop the charging process. If keep

charging, charger will continue balancing battery, if voltage dierence is less than 10mV, screen

will turn to blue. After that, charger will continue to precise balancing battery. If dierence is

small enough, after charging completion, charger jump to blue directly.

Due to the performance of dierent kinds of battery, after charging completion, voltage will fall

a little. This is normal. For battery used for a lot of times, this will occur more often. Charging with

higher current this circumstance would occur too.

Kind notice: For eld charging, if you would like to do quick charging, when screen shows green

it's ok to stop charging. If you would like to do precise charging, wait until blue.

Troubleshoot

Error in power on self-testing: the charger can automatically carry out a self-testing when
connected to a power supply. A self-testing error warning sound should be heard when the
charger is connected to the battery; power on after removing the battery for 5 minutes.

Error for abnormal battery connection: pull out and plug in the battery again to ensure all
connections are reliably contacted; if the error reminder continues, please check whether the
metal parts on the battery interface are oxidized or burned resulting in unreliable connection.

Error for unstable power voltage: check whether the battery socket is reliably connected, and
whether the power of electric supply can match the input requirement of the charger. If
capacity of PSU is less than charger's Max power, please adjust the max input power to match
the power of electric supply in the system fault menu of the charger.
