2S 7.4V 8.4V Li-ion BMS Lithium Battery Protection Board PCB for DIY 18650 Battery Pack

The 002S005A-0110-01 2S lithium battery protection board is a high-performance safety solution engineered specifically for 2-series (2S) lithium-ion and lithium-polymer battery packs, delivering reliable protection for mid-power electronic devices. As a dedicated 2S module, it’s optimized for battery packs with a nominal voltage of 7.4V (3.7V per cell), making it a critical component for maintaining battery integrity and device safety.

At its core, this protection board integrates a comprehensive suite of safety mechanisms to guard against common battery hazards. It features precise overcharge protection (triggering at 4.25V when cells exceed safe voltage to prevent swelling or thermal runaway), over-discharge protection (activating at 2.5V to avoid irreversible cell damage from deep discharge), and robust over-current protection (supporting a continuous current of 5A, with a 20A short-circuit cutoff to shield against excessive load or accidental shorts). Additionally, built-in over-temperature protection (65℃ threshold) ensures shutdown during extreme heat, while reverse polarity protection prevents damage from incorrect wiring.

Crafted with premium components, the 002S005A-0110-01 utilizes a high-precision protection IC for real-time voltage/current monitoring, paired with dual MOSFETs (charge and discharge control) for ultra-fast response—circuit disconnection occurs within microseconds of detecting anomalies, with automatic recovery once conditions normalize. Its compact PCB design and lightweight construction enable seamless integration into space-constrained applications, from portable power tools and small electric scooters to medical devices and DIY battery packs.

Whether for industrial equipment or consumer electronics, the 002S005A-0110-01 2S protection board balances durability, precision, and ease of use, providing peace of mind for both mass production and custom projects requiring stable, safe 7.4V battery operation.
