Lithium Polymer charger
TL-4 Instruction Manual
Thank you for purchasing our TL-4 Lithium Polymer battery charger, designed specially for lithium polymer battery packs up to 4-cell pack.
Features
01 Durable and light weight aluminium case 02 Charges the lithium polymer battery pack using its latest Constant Current and Constant Voltage charging
03 Charges each cell of the battery pack independently, eliminating the interferencebetween cells of thebattery pack.
This will ensure the proper 'balancing' of each pack after charging 04 Load polarity protection 05 Input polarity or reverse polarity protection 06 Built-in fan for maximum heat dissipation 07 Automaticallycut-off charging operation whenthe input power supplyvoltage falls below 8v.
Safety Precautions
01 Do NOT attempt tocharge incompatible types of rechargeable batteries. This chargeris designed to onlycharge
Lithium Polymer battery packs. 02 Make sure to place the charger on a firm level surface for charging 03 Do not attempt to charge batteries at excessive fast charge currents above the recommended charging current. 04 Do not leave the charger unattended while charging 05 Do not allow water, moisture or foreign object into the charger 06 Do not place the battery or charger on or near a flammable object while in use. 07 Do not cover the air intake holes or the fan on the charger as this could cause the charger to overheat 08 Connect the input power supply first, then connect the battery. 09 Do not disassemble the charger

Operation of the charger
INPUT POWER Connect the chargerto a 9-15v power source(Power supply must be able to provideat least 2Astable or regulated current).
All the LEDs on the charger will light up in green colour, indicating that the charger is in good status and ready for use.
CURRENT SELECTION Select the appropriate current setting (0.5A, 1.0A, 1.5A, 2.0A) according to the battery pack's recommended charging
current.
9-15vDC
8.4v for 2-cell lithium battery pack
12.6v for 3-cell lithium battery pack
16.8v for 4-cell lithium battery pack

SUGGESTED CURRENT SELECTION Here are some suggested guidelines are for selecting the appropriate charging current: a. 0.5Afor cells with 340mAH or higher b. 1.0Afor cells with 700mAH or higher c. 1.5Afor cells with 1200mAH or higher d. 2.0Afor 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.

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.
Status
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.
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.
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.
