The HXYP-7S-TY-T20 is a Battery Management System (BMS) designed for 7-series (7S) lithium-ion battery packs, providing a nominal voltage of 25.9V and a maximum charge voltage of 29.4V. It offers a continuous discharge current of 15A and peak discharge current up to 20A, ensuring efficient performance for various applications. This BMS safeguards your battery pack with comprehensive protection features, including overcharge, over-discharge, overcurrent, and short-circuit protection, thereby enhancing battery longevity and safety.

Key Features:

  • Voltage Management: Designed for 7S lithium-ion battery packs with a nominal voltage of 25.9V and a fully charged voltage of 29.4V.
  • Overcharge Protection: Activates at 4.25V ± 0.05V per cell to prevent overcharging.
  • Over-Discharge Protection: Activates at 2.5V ± 0.05V per cell to prevent deep discharge.
  • Current Handling: Continuous discharge current of 15A, with peak discharge current of 20A.
  • Safety Features: Protects against overcharging, over-discharging, overcurrent, and short circuits; includes passive cell balancing to maintain equal charge across all cells.
  • Compact Design: Dimensions of 60mm x 40mm x 6mm, facilitating easy integration into various battery packs.

Package Includes: 1 x 7S 25.9V 20A Li-ion BMS HXYP-7S-TY-T20.
