7.Safety message
Although the charger is designed to work in a stable environment to play a role, but in
use, you still need careful maintenance, as long as these important tips to follow, that is easy
and effective use of your charger!
1) When you start the process,especially the discharge process,the unit will become
warm,please keep clear of the heat area and do not cover it by anything when using
2) Do not keep it in a environment below 5 ℃ or above 50 ℃
3) Use it carefully,do not use it in a wet or corrosive environment
4) Keep all the inflammable volatile materials well away from operating area.
5) Please don't let the charger get hurt through falling ,bumping,stiking, shaking,
heavy press and so on.
6) Do not attempt the voltage higher than the requirement by manufactures
7) Ensure the type of battery and the voltage of the battery pack is selected correctly.Do
not use the different types or different capacities synchronously .
8) The standard accessories can only support one battery pack.When you are willing
to use multi- packs,please separately purchase the special accessories,never do
a disassembly or alteration to the charger
9) Do not attempt to charge/discharge the non-recharged batteryor damaged
battery.
10) Keep the charger away from children and pet at all time! Never leave the charger
unsupervised when it is connected to its power supply.
1. Special features:

1.8 For users convenience it can store and load maximum five data of different batteries. you can
establish the data contains program setting of the battery to charge or discharge continually.
these data can be called out at any time you need and the process can be executed without
program setting.
1.9 Perform 1-5 cycles of charge>discharge or discharge>charge continually for NiMH / NiCd
refreshing
1.10 You can connect a high-precision digital temperature sensor to protect the charger works in a
safety temperature .once a battery reaches the maximum temperature you set during charge/
discharge, the process will be terminated to protect the battery. this is very important for NiMH / NiCd
(separately purchased temperature sensor)

you need to set the upper limit of charge current to avoid from
higher feeding current that may damage the battery. Because
some batteries of low impedance and small capacity can lead
to the higher charge current by the processor at automatic
charge mode. But in "Man" mode, it will charge the battery with
the charge current you set at the display. Each mode can

the charger to your PC with an optional USB cable. this can utilize the optional software
that can show you the charge process at PC. (see the screen A4 )
When NiMH or NiCd battery is on the cyclic process of charge/discharge,it c a n
often become warm . The program insert a time delay to occur after each charge and
dis charge process to allow the battery adequate time to cool down before b e in g

The charger will automatically supply the trickle function to achieve the full charge
with out overheating the battery after fast charge has been teminated.you can alter
the trickle value when the charger shows you the screen A6
When you start a charge process, the integral safety timer automatically starts
running at the same time.this is programmed to prevent overcharge the battery if it
proves to be faulty,or if the termination circuit cannot detect the battery full. A7
shows you this program can be on or off,and you can set the maximum safety time,
the value ranges from 10 to 720min. As the same principle,there is a maximum-cap

"AUTO charging" this is for individual Lithium battery or some
special battery pack without balance port or cell count. The left
side of the first line shows the type of battery you select at the user
setting. The right side of the first line shows you the mode of
charge. The value on the left side of second line sets a charge
current and the value on the right side of second line sets the
cells count of the battery. the definition of the following screen
are all the same. (To know how to connect,plesase refer picture B)
"Balance charging" this is for 2-6 cells of Lithium battery with
balance port, the battery pack being charged should have
the individual cell connect, and connect it to the individual port
at the right side of charger with a suitable connection cable that
fits with your battery pack. (see picture B)I n t h is m o d e , t h e
chargin g process will be different from ordinary charging
mode. the internal processor of the charger will monitor and
control the voltage of each cell of the battery pack. This can
improve the discharging perf o r m a n c e of the battery! EV
charger use the optimised calculation to control the tolerance
in the range of 0.01V!
"Fast charging" select this mode to finish charging process earlier.
Principle: When the current down to 1/5 of the current you
set during the CV term, it will stop the process and eliminate the
forcible requirement of the balance precision. (whether it is
been connected to the balance port), the charging capacity
may be a bit smaller than normal charging but the process time
will be reduced.
"Storage mode " this is for charging or discharging Lithium
battery not to be used for the time being. In order to reduce
the wastage, you can select this mode to remain the power
to 40% to store. The final voltage are different from the type
of the battery, LiIo:3.75V、LiPo:3.85V、LiFe:3.3V. This is
an intellective program, If the voltage of battery at its initial
stage is over the volt age level to storage, the program will
start to discharge,and if it is lower, the program will start to
charge automatically. In order to ensure each battery meets
the demand, the individual plug of the battery pack should
be connected to the individual port of charger.
" Discharge mode " theoretically, Lithium battery do not need
to discharge, especially deep-discharge. This feature is to
ensure the power wastage of the Lithium battery over 90%,
Inc. to avoid the overcharge of the individual battery, you should
connect the balance plug of the battery to the charger, and the
current may not exceed 1C.
