is a switch that allows control of battery charging.
It ensures that the charge does not exceed a certain voltage or temperature threshold, in order to protect it.
If the voltage or temperature exceeds this threshold, the switch will turn off the charge to prevent damage to the battery.
The Cyrix-Li-Charge can also reactivate the charge after a certain delay if the voltage returns to a safe level.
The Cyrix-Li-Charge coupler protects batteries against undervoltage, overvoltage, and high or low temperatures.
It acts as a switch controlled by the Battery Management System (BMS) to shut down or reduce the battery charger load in case of abnormal conditions.
