Page 8: Battery Charging Stage
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. - Page 9 maximum current to the batteries (MPPT Charging). When the battery voltage reaches the constant voltage set point, the controller will start to operate in constant charging mode. b) Constant Charging When the battery voltage reaches the constant voltage set point, the controller will start to operate in constant charging mode.

Due to the installation environment or load work, the system may not stabilize the battery voltage at a constant voltage. The controller will accumulate the time when the battery voltage is equal to the set value. When the accumulative time equals 3 CAUTION hours, the system will automatically switch to float charging. -

Questions and answers
Have duoracer connected to 2 batteries does not seem to be charging batt2
The Epever Duoracer is not charging battery 2 (the starter battery) because the controller only provides a 1A trickle charge to battery 2, and this may not be enough to show noticeable charging activity on the Bluetooth app. Additionally, it is necessary to ensure that the BATT2 safety switch is turned on and that the controller is properly connected to BATT2. If these conditions are not met, battery 2 will not receive a charge.
