A1: Over-charge Voltage Cut-off (>15V): If the voltage of a single cell exceeds the specified threshold during charging, the BMS will stop charging. Over-discharge Voltage Cut-off (<8.8V): If a single cell falls below the specified threshold, when the battery voltage drops below 8.8V, the BMS will prevent further discharge. The battery will automatically reconnect when the voltage recovers to 10.8V. High Temperature Charging (>158°F/70°C) and Discharging (>167°F/75°C): If the internal temperature of the battery reaches 158°F (70°C), the BMS will not allow charging. If the internal temperature of the battery reaches 167°F (75°C), the BMS will not allow discharging. Low Temperature Charging (<32°F/0°C) and Discharging (<-4°F/-20°C): The BMS will not allow charging below 32°F (0°C), but will continue discharging down to -4°F (-20°C). Note: The operating temperature range for WattCycle 12V series products is -4°F (-20°C) to 140°F (65°C).
