BMS LFP 11S 20A JBD (HP16SA) (9977)

BMS LFP 11S 20A JBD (HP16SA) (9977) is a reliable battery management system designed for 11-series LiFePO4 battery packs (~36V). It supports 20A continuous discharge and provides advanced protection including overcharge, over-discharge, over-current, short-circuit, and temperature protection. The board features passive cell balancing to maintain cell voltage balance and improve battery life, making it ideal for electric bikes, solar storage systems, and DIY lithium battery packs.

The BMS LFP 11S 20A JBD (HP16SA) (9977) is a compact and efficient Battery Management System designed specifically for 11-cell LiFePO4 (LFP) battery packs. It ensures safe operation, balanced charging, and longer battery life by monitoring and protecting each cell in the battery pack.

This BMS supports a nominal battery pack voltage of approximately 35.2V (3.2V × 11 cells) and can handle 20A continuous discharge current, making it suitable for medium-power applications such as e-bikes, e-scooters, portable power packs, solar energy storage, UPS systems, and DIY lithium battery projects.

The board includes multiple protection mechanisms to ensure battery safety. It provides over-charge protection (around 3.65V per cell), over-discharge protection (~2.5V per cell), over-current protection, short-circuit protection, and temperature monitoring through an NTC sensor. These protections prevent battery damage and enhance system reliability.

The HP16SA BMS also features passive cell balancing (30–70 mA) to maintain equal voltage levels across all cells during charging. Balanced cells help improve battery performance, efficiency, and lifespan. Some versions also support communication interfaces like UART or Bluetooth for monitoring battery data and adjusting parameters through compatible software or mobile apps.

With its compact size, low power consumption, and reliable protection features, the JBD HP16SA BMS is a dependable solution for managing LiFePO4 battery packs in both commercial and DIY energy storage systems.
