On/Off Single Contactors 96 Volt Coils
You should use the same Volt Coil Contactor as the Battery Pack Voltage System.
You could tap into the Voltage of your Battery Pack to
switch Higher Voltages but is not recommended as this could cause some
Batteries to become out of "Sync" with others in your pack. Also if
these batteries become low in voltage it could cause the On/Off
Contactor to cut on and off.
