The device features three flashing LEDs; each LED can be used to configure your settings. To do that, choose the
appropriate LED (see below) ,and then press the switch for 5 seconds until the number starts flashing. Choose the
required number and release it, so that the number you set will be saved.
NOTE:
in the normal charging status, the controller will
divide the charge equally, when battery 1 is fully
charged, more charge current will be diverted to
battery 2, and then automatically return to charging
battery 1 when its voltage is low. When the controller
detects there is only battery 1, all the charging will
go to battery 1 automatically.
