Low Voltage Cut off - LVC --

This is an electrical unit that is usually installed between a LiPo battery pack and the ESC. Many ESCs are also available with integrated LVC. An LVC cuts off or drastically reduces voltage from the LiPo pack once the pack reaches a predetermined threshold - usually around 3.2 to 3.4 volts per cell. This prevents the pack from becoming overly discharged, which easily damages LiPo batteries. LVCs are usually rated for a certain number of cells (such as 2S or 3S), and some may allow the actual voltage threshold to be set by the user. LVCs for RC car use are commonly 'hard cut off', meaning all power to the ESC (and motor) is disabled once the voltage threshold is reached. 'Soft cut off' units are commonly used on electric aircraft - this just reduces the power at first, enabling the pilot to land before all power is lost.
