Connection for Charger
The Power Input Ground Cannot be Connected with the Output Ground
Connection for Channel Asynchronous Mode
Channel Asynchronous Mode: i.e. CH-1 and CH-2 work independently. Go to
MEMORY SETUP
→
Option
→
Channel
Mode
to select
Asynchronous
.
1. In this mode, the two channels must not have any external electrical connection; otherwise it will damage the charger.
You cannot charge with connection as shown in the left picture, the correct connection as shown in the right picture.
2. Please make sure CH1 and CH2 connect correct or the charger will be damaged and cause danger.
Connection for Channel Synchronous Mode
Channel Synchronous Mode: i.e. CH-1 & CH-2 are controlled at the same time to charge/discharge one battery pack. Go to
MEMORY SETUP
→
Option
→
Channel Mode
to select
Synchronous
.
In this mode, the maximum current can be up to 70A,
power capacity is the sum of both channels’ limits. At the same time, it is limited to the maximum power of 2200W. In the
synchronous mode of balanced charge and discharge, the user can connect to any balance port or connect to two balance
sockets in parallel at the same time (double the balance current).

4. Channel current & voltage difference
The two channels charge one battery pack simultaneously
must be connected as shown in the left picture and the
two channels must work in synchronous mode, otherwise
the charger will be damaged.
1. The input of power lead cannot be connected directly
to the output (left picture), and the voltage of the input
power supply cannot have large instantaneous
fluctuations, otherwise the charger will be damaged.
2. Input and output voltage can NOT be exceeded rated
voltage or the charger will be damaged.
