1.3 Structure
The controller is charging the BATTI as default (250C) without temperature compensation when it's not connected to
the remote temperature
designed for the lead-acid battery.
(2)The above two shared power ports are 5VDC/Max. 200mA, also the AES signal port is designed for AES
supported
car refrigerator,
1.4 Starter
battery
1)Working principle of the starter battery
The controller is trickling charge the BATT2 at IA constant current When the voltage reaches the "Full charging voltage"
during the BATT2 charging process, the controller will stop charging and quit the constant voltage charging mode.
2) Voltage control parameters of the starter battery
Item
Full voltage
Charge return voltage
CAUTION: Please follow the logic of Full Voltage
3) Start Charging Conditions
CAUTION: BATT2 ONLY supports lead-acid battery type, before start the BATT2 charging, please connect the
BATTI
first
Conditionl:
BATT2 starts charging when BATTI reaches the float charging stage and the BATT2 voltage is lower than the
"Charging Return Voltage.
Condition
2:BATT2 stans charging when the batteries total charging current is higher than GA and the BATT2 voltage is
lower than the "Charging Return Voltage.
