 It may be desirable to disable alternator charging on-the-fly when stopped in traffic, on hot days, to avoid charging frozen Li cells,((using a temperature controller)) stop charging at a given voltage,((using a [[electrical:12v:alternator_charging_hvd|High Voltage Disconnect]])) or neutralize [[electrical:12v:alternator#gotchas|gotchas]], etc.  The method of disabling will vary depending on the gear: It may be desirable to disable alternator charging on-the-fly when stopped in traffic, on hot days, to avoid charging frozen Li cells,((using a temperature controller)) stop charging at a given voltage,((using a [[electrical:12v:alternator_charging_hvd|High Voltage Disconnect]])) or neutralize [[electrical:12v:alternator#gotchas|gotchas]], etc.  The method of disabling will vary depending on the gear:
