TL-4
Lithium Polymer charger
TL-4 Instruction Manual
SUGGESTED CURRENT SELECTION
Here are some suggested guidelines are for selecting the appropriate charging current:
a. 0.5A for cells with 340mAH or higher
b. 1.0A for cells with 700mAH or higher
c. 1.5A for cells with 1200mAH or higher
d. 2.0A for cells with 1800mAH or higher
OUTPUT BATTERY CONNECTION
Select the correct charging ports according to the number of cell per pack. For example, a 2-cell pack can be inserted into
one of the two(2) 2-cell charging port as labeled on the charger. 2 LEDs on the charger will turn RED indicating that the
charger is now charging a 2-cell pack.
TL-4 INSTRUCTION MANUAL - 02
GREEN
Upon the connection of the power supply, the green LED indicates that the
charge is in good status and ready to charge.
During the charging process, if one of the LED changes to green,
it means the corresponding cell is defective.
At the end of the charge, all the LED will change to green,
indicating that the pack is fully charged.
RED
During the charging process, the RED LED indicates that
charging is in progress
After charging and the battery pack is left connected for 20-30 seconds,
if one of the LED changes to red colour, it indicates that one of the
corresponding cell is defective and may not be useable anymore.

Special attention
01 In order to charge a lithium polymer safely by way of independent-cell charging using this charger, the battery pack
should have an additional connector as shown in the diagram
02 Lithium polymer battery packs should be charged at least once every 3 months even when not in use, so
that it does not fall below the fatal 2.4v per cell.
03 If you are using the TL-4 as a 'serial-charging' charger (which will be able to charge the commonly packed
batteries with only the 2-pin JST connectors), the charger will no longer charge the cells independently. As such,
TL-4 will not be able to ensure that the voltage of each cell does not exceed 4.9v. Lithium batteries will explode
and burn if the cell exceeds 4.9v during charging.
The manufacturer shall not be responsible for consequences resulting from the use of the charger in 'serial charging'
technique or any other usage not specifically stated in this instruction manual.
