Daly 4S 50A Li-Ion Battery BMS With Balancing And Waterproof

The Daly 4S 50A Li-Ion Battery BMS (Battery Management System) with Balancing and Waterproof features is an advanced protective circuit designed for managing lithium-ion battery packs. This BMS is tailored for a 4S (4-series) configuration and can support higher currents, making it suitable for more demanding applications. Here’s a detailed description of its key features:

1. 4S Configuration:

• The BMS is designed for a 4S (4-series) lithium-ion battery pack, which includes four cells connected in series. This configuration provides a nominal voltage of 14.8V (3.7V per cell) and a fully charged voltage of 16.8V (4.2V per cell).

2. 50A Continuous Discharge Current:

• The Daly 4S BMS can handle a 50A continuous discharge current, which is ideal for higher-power applications like electric vehicles, e-scooters, e-bikes, or other battery-powered devices requiring higher current.

3. Battery Balancing:

• The BMS features cell balancing (either passive or active), ensuring all cells in the battery pack charge at the same rate and maintain equal voltage levels. This helps prevent overcharging or undercharging of individual cells, which can lead to uneven wear and potentially shorten battery lifespan.

4. Waterproof Design:

• The BMS is housed in a waterproof enclosure, ensuring that it can be used in environments exposed to moisture, such as outdoor applications. This protection prevents damage from rain or water splashes, enhancing the durability and reliability of the system.

5. Overcharge and Overdischarge Protection:

• The system includes overcharge protection to prevent the voltage from rising beyond safe limits (over 4.2V per cell) and overdischarge protection to avoid excessive discharge (below 3.0V per cell). These features help preserve the battery’s health and prevent permanent damage to the cells.

6. Overcurrent Protection:

• The BMS will automatically cut off the current if it detects that the discharge current exceeds the safe limit of 50A. This helps protect the battery pack from overheating or short circuits, preventing damage to the battery and other components.

7. Short Circuit Protection:

• It provides short circuit protection, which helps avoid the risk of fire or catastrophic failure if a short circuit occurs in the system.

8. Temperature Protection:

• The BMS monitors the battery temperature and has a built-in mechanism to shut off charging or discharging if the temperature goes beyond the safe threshold, preventing overheating and thermal runaway.

9. Low Voltage Protection:

• The system also features low voltage protection, cutting off power when the voltage drops too low, ensuring that the battery cells are not over-discharged, which could degrade their capacity and lifespan.

10. Communication Function (Optional):

• Some versions of this BMS may include communication ports (e.g., UART or CAN), allowing you to connect the system to a monitoring device or an external system. This enables real-time monitoring of battery health, voltage, current, and other parameters.

11. Compact and Durable Design:

• The Daly 4S 50A BMS is compact yet robust, making it easy to integrate into various battery packs while offering the protection and features necessary to keep the battery safe and efficient.

Applications:

• This BMS is suitable for higher-power applications such as electric bikes, electric scooters, solar energy storage systems, electric go-karts, and other electric vehicles that require higher discharge currents.

Summary:

The Daly 4S 50A Li-Ion Battery BMS with balancing and waterproof features offers superior protection for a lithium-ion battery pack. With its ability to handle up to 50A continuous discharge, it is designed for higher-power applications. Its battery balancing, overcurrent, overcharge, overdischarge, and temperature protections ensure the system is safe, reliable, and long-lasting. The waterproof design further enhances its suitability for use in outdoor environments, making it an excellent choice for demanding battery-powered applications.
