please terminate the process immediately and refer to the manual.
•Never put the charger into the place which dust/damp/vibrate.
•The input power is only for DC 10-18V.
•Please put it onto the surface which it is firm/Anti flammable. Never put it onto the carpet
or others similar objects. Make sure it is far away from the Anti flammable area.
•Never cover the fan, keep the cooling fan well ventilated .
•Make sure the correct setting data, if the program was setting wrong, it will damage the
battery. Especially for the Li-xx battery, it will explode due to the over charge/discharge.
•It should be connect the cable to the charger first then connect the battery. When
disconnecting, the opposite operation
•User must check the voltage and capacity of the Li-xx battery pack before using. The
battery can be Series connection or Parallel connection. When it is paralleled, the capacity
of the battery pack is the total capacity of each single battery and the voltage of battery
pack will not change. It is suggested to choose the Series connection for the li-xx battery
because it possible to lead the explosion if the voltage is un-balance when charging.

Discharge
•The discharge parameter should be set according to the rest of battery capacity or
decreased battery voltage. When discharging, it should be pay more attention to the
discharge process. It must set the correct discharge voltage, in order to avoid the over
discharging. Li-xx battery cannot lower than the lowest voltage, because it is easy to
damage the battery. Normally, it do not need to discharge for the Li-xx battery.
• Some batteries have memory function. If the capacity is partly used, they will remember it
and use that part of capacity only next time. This is called memory function. NiCd /NiMH
batteries also have memory function, but they prefer fully charged and then completely
used. NiMH battery's memory function is inferior when compared with NiCd battery.
• The Lithium battery prefers a partial rather than a full discharge. Frequent full discharge
should be avoided if possible. Instead, charge the battery more often or keep a normal
input power
•It should finish 3-5times circle charging and discharging for the new NiCd battery pack. In
this way, the capacity of this battery pack will be to the best status.
The above warnings and safety notes are particularly important. Please follow the
instructions for a maximum safety, otherwise the charger and battery can be badly
damaged. Also it can cause a fire, lead to human injury or property loss.

6、How to set charge current
-8-
Each battery has its permitted maximum charging current. Charging current over the
battery permitted maximum charging current will shorten the battery life and even damage
the battery. Too much charging current may also cause battery heating or even explosion.
The capacity of battery charging and discharging is generally identified by C value
Multiplied by battery capacity is the battery accepted maximum charging current. For
example, the battery of 1000mAh, the charging capacity is 5C, so the maximum charging
current is 1000*5=5000mA, that is, the battery maximum support 5A charging.
For lithium batteries, if don’t know its C value, please set the charging current value not
more than 1C.

battery pack.
After setting the current and voltage press Start/Enter
key for more than 3 seconds to start the process.
(Charge current:0.1~6.0A,Voltage:1~6 series)
Use these programs only when charging a lithium battery ( Lilo/LiPo/LiHV/LiFe) with
a nominal voltage of 3.6V, 3.7V, 3.8V or 3.3V per cell, respectively. The charge current
going into the battery will vary depending on the chemistry type so it is VERY
IMPORTANT that you select the correct type for your battery. The ending voltage
of the charge is also important as it varies for all four types:4.1V for Lilo, 4.2V for LiPo,
4.35V for LiHV and 3.6V for LiFe. The charge current (how many Amps you are
putting into the pack) and nominal voltage(Proper voltage for the cell count of the
battery you are charging) must be correct for the battery to be charged. To change these
settings, press the START/ENTER key to make the selected value blink. Using the
increase and decrease buttons, set you desired amperage, then press START/ENTER
to save the setting. You will then be asked to select your nominal voltage/cell
count. Again, use the increase/decrease buttons to reach your desired setting and
press the START/ENTER button to confirm and save.
The relationship between the C value and the charging time: charging time≥
60min/charging c value(for example, it need 60-70 minutes to complete 1C charging ).Due
to battery differences in energy efficiency conversion, this time may be extended.

'discharge' of Lithium battery pack. It tries to normalise the voltages to be equal.
For this feature, the individual plug of the battry pack should be connected to the
individual port of the charger.
If the voltage of any one or more cells varies abnormally during the procedure, It
terminates the process forcibly with the error massage. If this happens, the battery
pack contains the bad cell, or the bad connection of the cable plug. You can easily
know which one cell is bad by pressing INCbutton at time of showing the error
message.
The processor found that the voltage of one of the cell
in the Lithium battery pack is too low.
In this case, the 4th cell is bad. If there happens the
connection-break of th cable or plug, the voltage value
may show zero.
