Reliable Protection for 18650 Battery Packs

A BMS is an important part of a lithium-ion battery pack because it monitors the cells during charging and discharging. The DALY 6S 24V 20A BMS provides multiple protection functions to help prevent conditions that could damage the battery cells.

It monitors the voltage of individual cells and provides protection against overcharge and over-discharge. It also includes overcurrent and short-circuit protection, helping protect both the battery pack and connected equipment during abnormal operating conditions.

20A Continuous Discharge Capability

This DALY BMS is designed to handle a continuous discharge current of up to 20A. Its low-resistance, high-voltage MOSFETs help reduce power losses while the integrated heat dissipation design assists with managing operating temperature.

For best results, the BMS should be selected according to the battery pack’s cell type, configuration, maximum charging current, and required discharge current.

Cell Balancing and Voltage Monitoring

The board monitors the voltage of individual cells within the 6S battery configuration. Its balancing function helps maintain better voltage consistency between cells, which is important when multiple lithium-ion cells are connected in series.

Proper cell matching and correct BMS installation are still important for achieving reliable battery pack performance.

Protective PCB Design

The PCB uses a protective conformal coating designed to improve resistance against corrosion, moisture, and ESD-related conditions. The low-power design also helps minimize the BMS’s own energy consumption.

Applications

The DALY Li-ion 6S 24V 20A BMS can be used for a variety of 18650 battery projects, including:

• DIY 18650 battery packs
• 24V lithium-ion battery packs
• Portable power systems
• Robotics projects
• Electric electronics projects
• Rechargeable battery systems
• Custom battery packs
• Backup power projects
• DIY energy storage applications

Important Compatibility Note

This BMS is designed for 6S Li-ion battery packs using suitable lithium-ion cells such as 18650 cells. It is not intended for LiFePO4 batteries. Always match the BMS with the correct battery chemistry, number of cells in series, charging voltage, and current requirements before installation.
