How to Estimate the Battery SOC?
The SOC values listed below are estimated based on the open circuit voltage when the battery is
at rest for 30 minutes, not in charging or discharging state.
SOC Open Circult Voltage SOC Open Circult Voltage
100% 13.6V 30% 12.9V
99% 13.4V 20% 12.8V
90% 13.2V 14% 12.7V
70% 13.1V 9% 12.6V
40% 13.0V 0% 10.0V
The table above is for reference only because slight variations in battery voltage may occur
among different batteries.
Self-Heating Function
The normal operation of the self-heating function requires a stable charge current greater than
4A for each battery in the parallel battery bank. The self-heating function will start operating
automatically once the battery and the battery temperature drops below 41°F (5°C) and stop
operating automatically once the battery temperature rises above 50°F (10°C). The temperature
rise rate is approximately 51.8°F (11°C) per hour when running at full power of 55W (4A).
Battery Management System
This smart battery management system has more than 60 fault alarms and protections to fully
protect your battery safety. Below we list some common faults and protections for reference.
