This is a Lithium battery protection board, often known as a battery management system, for LiFePO4 batteries. The board's design is lightweight, making it simple to store and move. Overcharging and over-discharging protection, as well as short circuit and overcurrent protection, are all included on the board. This board may also be used to charge lithium batteries, as long as they are rechargeable. We can construct a battery pack with a voltage rating of up to 15V DC by combining 4 LiFePO4 electric cells with this BMS system.
Features
- High-accuracy voltage detection circuit;
- Terminal of the charger using a high voltage device;
- Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);
- MOS transistor can control the battery charge and discharge;
- Low standby current consumption.
