8S 35A LiFePO4 Battery Management System (BMS) with Cell Balancing

The 8S 35A LiFePO4 Battery Management System (BMS) is designed to protect and manage an 8-cell series lithium iron phosphate battery pack. Suitable for nominal 24V-class battery systems, this protection module monitors individual cell voltages and helps prevent unsafe operating conditions during charging and discharging.

Featuring integrated cell balancing and an aluminum heat sink, the module helps maintain more consistent cell voltages while dissipating heat generated during operation. Its common-port design supports charging and discharging through the designated shared connection, simplifying integration into compatible battery systems.

This BMS is suitable for DIY battery packs, backup power applications, and low-power energy storage systems that require cell-level protection and balancing.

Features:

• 8S LiFePO4 Support: Designed for battery packs containing eight LiFePO4 cells connected in series.

• 35A Discharge Rating: Supports discharge currents below the stated 35A rating.

• Cell Balancing: Helps reduce voltage differences between individual cells during the balancing process.

• Overcharge Protection: Helps prevent individual cells from exceeding the specified voltage limit.

• Over-Discharge Protection: Disconnects the battery output when a cell reaches the protection threshold.

• Short-Circuit Protection: Helps protect the battery pack and connected equipment against short-circuit conditions.

• Aluminum Heat Sink: Provides a heat-dissipation surface for the power components.

• Common-Port Design: Uses a shared connection for charging and discharging on compatible wiring configurations.

• Balance Cable Included: Provides cell-sensing connections for monitoring and balancing the eight-cell pack.
