Tips
1. In main interface, press for 3 seconds, the charger will enter into function interface directly,
press for 3 seconds will operate last program directly.
2. During charge in CC phase, the charge current can be set up to new value
and need not stop charging. On Cells and Info page, press Knob button for
3 seconds, Ch. Current modification window is pop up, please press Knob
and rotate Knob button modify charge current, press Esc quit and press
Ok save the change. he charger will charge at new current.
And rotate Knob to alternate Cells, Info and IR label page, on Info page,
you will check some preset
parameters and actual input power.
On IR page, you can check each cell
impedance and total battery
impedance
3. During discharge, the discharge terminal voltage can be changed and
need not stop discharging, On Cells and Info page, press Knob button for
3 seconds, Disch. End.Voltage modification window is pop up, please
press Knob and rotate Knob button modify end voltage per cell, press Esc
quit and press Ok save the change. he charger will continue to discharge
and stop at new terminal voltage.
4. On Li o, LiPo&Hv and LiFe battery balance charge program, Enable
“Charging Keep After Done”, continue to charge at smaller current when

battery, if you have one battery pack under 6S such as 2S, 3S, 4S, 5S, you can connect the battery to balance
port by adapter board, if you have two battery but total cell count is under 6S such as 3S+3S, 2S+2S, he
connection is as below, two 3S packs will be charged as one 6S pack.
1. Connect two packs with heavy wire in series (as same as the Blue wire in following picture). ake two 3S
battery as sample.
2. Plug 1# battery and 2# battery into adapter board, if plug into mistaken socket, the red LED will be on,
please exchange the connector and plug it again.
3. Connect total battery pack positive to charger output port B+, and connect battery negative to output port
