LVD ( Low Voltage Disconnect, 2A rate) for 12V/ 24V/36V/ 48V LiFePO4 battery pack (#6871)

The Low Voltage Disconnect (LVD) is used to disconnect loads from Lithium battery pack when it becomes over discharged. This will prevent damage and reduction of capacity due to over-discharge. LVD is designed as part of low cost solution for low voltage systems (48V and below), such as golf carts. A complete low cost solution will include Lithium battery pack, cell balancing circuit, Lithium battery charger and LVD circuit.
