Operating Instructions
When the charger is connected to the power supply the charger will show the battery mode
that has been last used.
If the battery TYPE button is briefly pressed, the present battery type (NiCd, NiMH,
Lithium, or Pb ) will blink.
While the existing battery type is blinking, every time the battery TYPE button is pressed,
the following modes are shown in order. NiCd NiMH Lithum Pb NiCd
If the other buttons are pressed, or nothing is pressed, the present battery type stops blinking.
If the Battery type button is pressed and briefly held, the recent & previous data will be
shown for 3 seconds.
If the Enter button is briefly pressed, a parameter which can be adjusted starts to blink and
if the Enter button is pressed again, the next parameter starts to blink. If nothing is pressed
for 3 seconds, the parameter stops blinking.
Once the Enter button is pressed and briefly held, the charger starts to charge or discharge
according to the selected parameters.
- Operation -
Two 4mm banana sockets are located on the right side of the charger. Connect the battery
charge lead to these sockets with the positive (+) lead connected to the red socket and the
negative (-) lead to the black socket. The “No battery“ error message will be displayed if
trying to start to charge without connecting a battery. The “Open circuit” error message
will be displayed if a battery becomes disconnected from the charger while a function is in
progress. A “Reverse polarity” error message will be displayed if a battery is connected to
the charger in reverse.
Note.
In order to balance lithium batteries during charge or discharge, pls ensure that both battery
charge leads and balancing connector on the battery pack should be connected to both two
4mm output banana sockets and balancing port together on the charger.
If the battery charge leads are ONLY connected to the output banana sockets without connecting the balancing connector on the lithium battery pack at the balancing port on the charger,
the charger should charge or discharge the connected lithium pack without balancing the pack.

This charger is capable of charging Lithium-Ion, Lithium-Polymer and LiFePO4 batteries up to 6 cells. This
charger uses “constant current / constant voltage“ in order to fully charge those lithium batteries. Constant
current is delivered during the fast charge. When the voltage of the Li-Ion, Li-Po battery and LiFePO4 reaches
approx 4.1V, 4.2V, and 3.7V per cell, the charger starts to change its charge method from “constant current” to
“constant voltage “. The “constant voltage“ allows the battery to dictate how much current the charger should
deliver for safe, full charges. When the current drops below approx 1/10 currents of user selected battery capacity, the charger will stop charging as the battery is fully charged.

BALANCER CON.
CONNECTED
The left screen should be shown if lithium charge or discharge starts with connecting the
balancing cable to the balancing port of the charger.
For safety purposes, this charger is designed to automatically deliver a 1C charge rate to batteries of
Li-Ion, Li-Po or Li-Fe, based on the user selected battery capacity.
Example: Li-Po cell of 1500mAh capacity : 1C = 1500mAh ( = 1.5A ) charge current.
Note : The maximum voltage for Li-Ion is 4.1V per cell, 4.2V per cell for Li-Po batteries, and
3.7V per cell for Li-Fe batteries. Therefore, it is extremely important to choose the proper
battery type to be charged, as each Lithium battery has the different voltage level. Otherwise,
it may cause very serious damage to the batteries and increase the risk of a fire !
