LiFePO4 8S 24V BMS Protection Board | 15A–25A Common Port with NTC Temperature Sensor

Keep your 24V lithium iron phosphate battery packs running safely and efficiently with this 8S LiFePO4 BMS Protection Board. Designed for solar storage systems, e-bikes, power tools, backup power stations, and other 24V LiFePO4 applications, this battery management module monitors and protects your cells from overcharge, over-discharge, overcurrent, and short-circuit events — all in a compact SMD package.

The integrated NTC (Negative Temperature Coefficient) thermistor continuously monitors battery temperature, providing an additional layer of safety by triggering protection when temperatures exceed safe operating limits. The common port design simplifies wiring by sharing charge and discharge connections through a single port.

Frequently Asked Questions

Q: What does the 8S LiFePO4 BMS Protection Board do?

A: This BMS (Battery Management System) board monitors and protects an 8-cell series LiFePO4 battery pack at 24V nominal voltage. It guards against overcharge, over-discharge, overcurrent, short-circuit faults, and over-temperature conditions using a built-in NTC thermistor, ensuring your battery cells remain balanced and safe during both charging and discharging cycles.

Q: What is the difference between the 15A, 20A, and 25A variants?

A: The three variants differ in the number of MOSFET switches on the board — 6 MOSFETs for 15A, 8 MOSFETs for 20A, and 10 MOSFETs for 25A. A higher MOSFET count allows the board to handle greater continuous current safely. Choose the rating that matches or slightly exceeds the maximum current draw of your specific application.

Q: What is a "Common Port" BMS design?

A: A common port BMS uses the same set of terminals for both charging and discharging the battery pack. This simplifies wiring compared to separate port designs, making it popular for DIY solar and backup power projects where a single connection point is preferred.

Q: Is this BMS board compatible with solar charging systems?

A: Yes. This 8S 24V LiFePO4 BMS board is well-suited for use with solar charge controllers designed for LiFePO4 chemistry. The NTC temperature sensor adds an extra layer of protection in outdoor solar installations where temperature fluctuations can be significant.
