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

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.
