2S 7.4V 8A Li-ion Battery Protection Board BMS

The 2S 7.4V 8A Li-ion Battery Protection Board is a highly reliable Battery Management System (BMS) designed to safeguard your dual-cell lithium-ion or lithium-polymer battery packs. Operating with a standard voltage of 7.4V and a peak charging voltage of 8.4V, this compact module continuously monitors your cells to prevent hazardous overcharging, over-discharging, and short circuits, ensuring maximum lifespan and safety for your custom power solutions.

Capable of handling a continuous discharge current of 8A and peak instantaneous currents up to 15A, this BMS is perfectly suited for medium-draw applications. It is an essential component for DIY electronics makers and engineers building custom 18650 Li-ion battery packs for RC drones, robotics, portable lighting, and small power tools, providing professional-grade electrical protection in a minimal footprint.

Features:

• 2-Cell Management: Engineered specifically to protect 2S (7.4V nominal) Li-ion and LiPo battery configurations.
• Comprehensive Protection: Actively prevents overcharge, over-discharge, and electrical short circuits.
• Current Handling: Supports a reliable 8A continuous operating current with a 15A current limiting threshold for sudden spikes.
• Compact Footprint: Space-saving design allows for easy integration into tight battery pack heat shrink enclosures.
• Universal Cell Compatibility: Works seamlessly with standard 3.7V 18650, 21700, and standard Li-Po cells. (Note: Not compatible with 3.2V LiFePO4 cells).

Package Includes:

1 x 2S 7.4V 8A Li-ion Battery Protection Board
