The temperature compensation is ONLY designed for the lead-acid battery.
For lithium batteries, there is no temperature compensation.
⑵ For DR1106/2106/3106N models, AES port (outputs 12V/200mA) and RS485
port(outputs 5V/200mA) are independent. The 12V output voltage is the
battery voltage.
For DR1206/2206/3206/2210/3210N models, the AES port and RS485 port
share the power of 5VDC/Max. 200mA.
The AES signal port is designed for car refrigerators supporting the AES
signal. It is built into a power switching device.
1.4 Battery charging stage
Note: The following instructions for the battery charging stage are suitable for
the main battery (BATT1). Charging instructions for the starter battery (BATT2)
refer to chapter 1.5.
The controller has a three-stage battery charging algorithm, including Bulk Charging,
Constant Charging, and Float Charging. The system can extend the battery's lifespan
through the three-stage charging method.

a) Bulk Charging
The battery voltage has not yet reached the constant voltage (Equalize or Boost
Charging Voltage). The controller operates in constant current mode, delivering its
