150 +* Enable – a flag to enable the protection;
151 +* Minimum charge temperature, °C;
152 +* Tolerant charge temperature, °C;
153 +* Minimum discharge temperature, °C;
154 +* Tolerant discharge temperature, °C;
155 +* Delay before setting the error, millisecond;
156 +* Delay before clearing the error, second;
157 +* Lock – a flag to block the error until the device is restarted.
158 +
159 +As a result of the operation of the battery protection from low temperature, the "Low temperature (CH)" and/or “Low temperature (DCH)” error are generated.

161 +Error generation conditions:
162 +
163 +* the minimum temperature among all cells of the battery is less than the “Minimum charging (discharging) temperature” value for the “Delay before setting the error” time.
