Special Features 

13

 

The  DX8  uses  advanced  Synchronous  buck-boost  DC/DC  converter  technology,  high  power,

 

a  high  current  and 

high-performance  power  conversion  circuit.  The  maximum  charge  power  capacity  is  up  to  1600W,  the  maximum 

charge/discharge current of a channel is up to 30A, and two channels in Synchronous Mode are up to 50A. 

14

 

Each  channel supports  8s LiPo,  Lilo,  LiFe,  LiHV, LTO  and  NiZn batteries, with maximum  2A balance current, and 

adopts a unique balance calculation of internal resistance correction. Supports 1-25s NiMH/NiCd batteries and 1-15s 

Pb batteries. 

15

 

With  digital-power  mode  for  great  protection  (over-current  protection,  over-voltage  protection,  input  under-voltage 

protection, input undercurrent protection, and etc.) 

16

 

With type-c PD charging port, convenient for the user to charge mobile phones and PCs. 

17

 

Intelligent  fan  control.  Sensing  internal  temperature  via  the  internal  temperature  sensor,  to  thereby  control  the  fan 

speed. 

18

 

Internal  temperature  protection.  When  the  internal  temperature  exceeds  the  Power  Reduce  temperature,  the  output 

power is automatically reduced; and the charger will shut down when temperature exceeds the Shut-down temperature. 

19

 

This charger can save 64 parameters sets and support the data import/export to SD card. 

20

 

A  2.4

"

  IPS  LCD  screen  provides  rich  information  including  current,  voltage,  power,  capacity,  internal  resistance, 

control status, time-consuming and temperature, etc. 

21

 

Multi-discharge features: self-discharge, regenerative to input or discharge to another channel, and lithium battery extra 

expanding discharge. 

22

 

Supports measurement for internal resistance of battery offline and online.    Measure not only the internal resistance of 

the entire battery pack, but also measure the internal resistance of each cell within the lithium battery. 

23

 

DX8 has protection for reversed polarity (input or output), input voltage/current, battery temperature, charging capacity, 

overrun time and maximum power etc. 

24

 

Supports upgrading the hardware program by USB port or SD card. DX8 also supports the “Junsi Console” software 

and can display, plot and analyze the charge and discharge data by it.
