2S 10A LiFePO4 BMS 6.4V Protection Board Price in Bangladesh

The 2S 10A LiFePO4 BMS 6.4V Protection Board is a compact battery management and protection module designed specifically for 2-cell series LiFePO4 battery packs. It provides essential electronic protection for rechargeable lithium iron phosphate batteries by monitoring the individual cell voltages and controlling the charging and discharging paths when unsafe conditions are detected.

A 2S LiFePO4 battery pack consists of two LiFePO4 cells connected in series. A single LiFePO4 cell has a nominal voltage of approximately 3.2V, so two cells in series provide a nominal battery voltage of approximately 6.4V. When fully charged, the pack voltage is higher than its nominal value. Because two cells can behave differently during charging and discharging, using an appropriate BMS is important for protecting the battery pack and maintaining reliable operation.

The 2S 10A LiFePO4 BMS is designed to monitor the battery pack during normal operation and provide protection against conditions such as excessive charging voltage, excessive discharge, excessive current, and short circuits. This makes it suitable for DIY battery packs, portable electronics, LED systems, small backup power systems, robotics, RC projects, and other low-voltage applications that use two LiFePO4 cells in series.

One important feature of a BMS is its ability to monitor the battery cells rather than simply treating the complete pack as one voltage source. In a 2S configuration, the voltage of each cell needs to remain within its appropriate operating range. If one cell becomes significantly higher or lower than the other, the battery pack can become unbalanced. Depending on the exact BMS design, the protection circuit can help prevent unsafe charging or discharging conditions.

The board is rated for applications requiring up to approximately 10A continuous current, subject to the exact board design, thermal conditions, wiring, connectors, and manufacturer specifications. It should therefore be paired with a battery pack and load that remain within the BMS’s actual current capability.

This protection board is particularly useful when building custom 6.4V LiFePO4 battery packs. Instead of designing a protection circuit from individual components, users can install a dedicated BMS module to provide the essential protection functions in a compact PCB.

The module is also useful for electronics enthusiasts and technicians who convert older battery-powered equipment to LiFePO4 chemistry. However, the charger must be compatible with a 2S LiFePO4 battery pack. A charger designed for ordinary lithium-ion batteries should not automatically be assumed to be suitable for LiFePO4 chemistry.

For DIY battery construction, correct wiring is extremely important. The BMS generally has separate connections for the negative side of the pack, the midpoint between the two cells, and the positive side of the pack. Incorrect wiring can damage the protection board or battery cells. The exact terminal labels should always be checked against the PCB markings or manufacturer’s wiring diagram before connection.

With its compact size, simple connection method, and multiple battery protection functions, the 2S 10A LiFePO4 BMS 6.4V Protection Board is a practical component for anyone designing a small 2S LiFePO4 rechargeable battery system.

🔍 What is a 2S LiFePO4 BMS?

A 2S LiFePO4 BMS (Battery Management System) is an electronic protection circuit designed for a battery pack containing two LiFePO4 cells connected in series.

Each LiFePO4 cell has a nominal voltage of about 3.2V. Connecting two cells in series produces a battery pack with approximately 6.4V nominal voltage.

The BMS helps protect the battery pack against:

• Overcharging
• Over-discharging
• Excessive current
• Short circuits
• Unsafe operating conditions

It also provides the electrical interface needed to monitor the two-cell battery configuration.

⚡ Working Principle of 2S 10A LiFePO4 BMS 6.4V Protection Board

The BMS is connected to the two LiFePO4 cells in a series configuration. It monitors the voltage of the individual cells and controls the charging and discharging path through electronic switching components.

During charging, the protection circuit monitors the cell voltages. If a cell reaches an unsafe voltage threshold, the BMS can disconnect or restrict the charging path to help prevent overcharging.

During discharge, the BMS monitors the battery voltage. If a cell falls below the permitted discharge threshold, the BMS can disconnect the load to help prevent excessive discharge.

The over-current protection function monitors the current flowing through the battery protection circuit. If the current exceeds the designed protection threshold, the BMS can disconnect the output. Similarly, if a short circuit occurs, the protection circuit can rapidly interrupt the current path to reduce the risk of damage.

The BMS therefore acts as an electronic safety layer between the LiFePO4 battery cells, charger, and connected load.
