3S 20A Lithium-ion 12V BMS

price/ 70.00 off/Rs -30 off Here are some common specifications for a 3S 20A Lithium-jon 12V BMS:

1. Cell Configuration: 3 series-connected cells

2. Maximum Continuous Current: 20 Amperes (A)

3. Maximum Peak Current: The BMS may have a higher peak current rating for short durations, such as 20A to handle brief surges in power demand.

4. Nominal Voltage: 12 Volts (V)

5. Overcharge Protection Voltage: The BMS monitors the cell voltages and protects against overcharging by disconnecting the charging source when the

voltage exceeds

a specific threshold. The overcharge protection voltage for each cell is typically around 4.2V, resulting in a total pack voltage of 12.6V.

6. Overdischarge Protection Voltage: The BMS prevents excessive discharge of the cells by cutting off the load when the voltage drops below a safe threshold. The overdischarge protection voltage for each cell is usually around 2.7V, resulting in a total pack voltage of 8.1V.

7. Balancing Function: ine BMS neips maintain balanced cell voltages by actively equalizing the voltage levels across the cells. This ensures that all cells in the battery pack are charged and discharged evenly, maximizing the overall capacity and lifespan of the battery.

8. Temperature Monitoring: The BMS may have temperature sensors to monitor the battery pack's temperature. It can take appropriate actions, such as reducing the charge or discharge current if the temperature exceeds safe limits.

9. Communication: Some BMS models may include communication interfaces like UART, CAN bus, or I2C, allowing for data exchange and integration with external systems, such as battery monitoring systems or control panels.

10. Protection Features: The BMS may provide additional protections like short-circuit protection, overcurrent protection, and overtemperature protection to safeguard the battery pack from potential risks.

It's important to note that specific BMS models may have variations in their specifications and features. Therefore, it's recommended to refer to the product documentation or manufacturer's datasheet for precise details about a particular
