packs. It can be used to charge 4 ea 1 cell packs (optional by using 2 ea series charge
adaptor cables for port of 7.4V), or 2 ea 2 cell packs, or 1 ea 3 cell packs or 1 ea 4 cell packs.
6.LED indication, red color for charging, green color for charger ready or battery cell fully
charged.

control the charging process of each cell of the battery pack. It will completely eliminate the
interference between cells of the battery pack during charging process. It will also avoid the
possibility of fire or explosion caused by a problem battery pack with defective cell(s) inside.

Specification
1.Potential Fire or Explosion Hazard of batteries or packs
charged by series charging technique
Most of the Li-ion/polymer chargers on the market are
using series charging technique to charge the Li-xx
batteries. The series charging technique is circuit
connected as Drawing 1 indicated. In case, if one of the
cells of the battery pack is defective & can’t be full
charged up to its defined full voltage level, the other good
cell or (cells) will then be over charged. Take cells in
drawing 1 for example, if cell A is defective & can only be
charged up to 2.8V or lower, the good cell B will then be
overcharged up to 4.2 + (4.2-2.8) = 5.6V or higher. A
Li-xx battery can only stand its maximum voltage up to
4.6~4.9. If it is over 4.9V, it can burn or explode. Series
charging is necessary for battery packs that must be
charged through the discharge wires.
2.Parallel charging technique of our charger-circuit
connected as drawing 2 Dotted Lines
Instead of charging all cells of the battery pack in series,
our charger is designed to control the charging process of
each cell of the battery pack independently or in parallel.
It will completely eliminate the interference between cells
of the battery pack during charging process. It will also
reduce and avoid the possibility of fire or explosion caused
by a problem battery pack with defective or unbalanced
capacity cells inside.
3.Special battery pack package style is required
The battery packs to be charged on this charger should be
assembled as in drawing 2. Every battery pack should
have one additional charge connector. By connecting this
connector to the respective charger out-put port, you are
now safely charging to your Li-xx battery packs.
4.Life of the Li-xx battery packs
When in storage and not in use, the Li-xx battery will have
a self-discharge process. It will be severely damaged or
rendered unusable if it is allowed to discharge to less than
2.4V. It is strongly recommended to check / recharge all
Li-xx batteries once every 3 months.
5.The number of cells of the battery packs being charged by
this charger is limited at 4 cells maximum.
That is, the charger is not allowed to charge a 3 cell pack
& a 2 cell pack at the same time, or a 4 cell pack & any
additional batteries at the same time.
6.DISCLAIMER
The manufacturer or distributor shall not be held
responsible for any miss-use of the charger.
1.Connecting charger to power source, LED display will be
green, indicating that the charger is in good status &
ready to use. Set Current Select to suitable position: 0.5A
--- For cells with 360 mAh or higher, 1.0A --- For cells with
750 mAh or higher, 1.5A --- For cells with 1200 mAh or
higher. 2A --- For cells with 1800 mAh or higher. When
charging multiple cells or packs of different capacities at
the same time, charger must be set to the setting of the
lowest cell.
2.Select correct charger output ports (connectors) for the
battery packs to be charged. There are 4 out-put ports of
the charger, the two ports labeled 7.4V are for 2 cells
(3.7V x 2), the port labeled 11.1V is for the 3 cell battery
packs & the port labeled 14.8v is for the 4 cell battery
packs. After connecting battery packs to the charger, a
short auto-check of each cell of the battery pack will be
done by the charger. After the auto-check, the charger will
start charging each cell of the battery pack independently.
During charging process, if the cell is good the
corresponding LED display will change to red; otherwise, if
the cell is defective, the corresponding LED display light
will be green.
3.When charging starts, for a good battery pack, the number
of the LED displays which change color into red shall be
the same as the number of the cells of the battery pack.
For example, a 2 cell battery pack will have 2 LEDs in red
color during charging, a 3 cell battery pack will have 3
LEDs in red color during charging, a 4 cell battery pack
will have 4 LEDs in red color during charging.
4.When the battery pack is fully charged, all corresponding
cell - LED colors will change from red to green. This
indicates the battery pack is fully charged and ready to
use any time. If the battery pack remains on the charger
after fully charged, the charger will re-charge the batteries
when the voltage of the battery cell (cells) is less than
4.15V.
5.Within 20-30 seconds after the battery or pack is fully
charged, the charger will detect and indicate any problems
by changing the LED colors from green to red for a
defective or failing battery. If the charger detects a
defective or failing battery, the defective or failing battery
should not be used.
