1S 2S 3S 4S 3A 20A 30A Li-ion Lithium Battery 18650 Charger PCB BMS Protection Board for Drill Motor Lipo Cell Module

The 3S Lithium Battery Protection Board is a critical safety and performance component engineered exclusively for 3-cell series (3S) lithium battery packs, including Li-ion, Li-polymer, and LiFePO4 configurations. Designed to prevent battery damage and mitigate safety risks, this board acts as a “guardian” for 3S battery systems, ensuring stable operation and extending the lifespan of connected battery packs—making it essential for consumer electronics, industrial devices, and portable power solutions.

Core Protection Functions for 3S Battery Packs
Tailored to 3S battery packs (typical nominal voltage: 11.1V for Li-ion, 9.6V for LiFePO4), this board delivers multi-layered safeguards:
  • Overcharge Protection: Triggers when any cell voltage exceeds 4.25V (Li-ion) or 3.65V (LiFePO4), cutting off charging current to avoid cell swelling or thermal runaway.
  • Undervoltage Protection: Shuts down discharge when a cell drops below 2.5V (Li-ion) or 2.0V (LiFePO4), preventing irreversible battery capacity loss.
  • Overcurrent & Short-Circuit Protection: Instantly blocks high currents caused by short circuits or overloads (e.g., faulty devices), protecting both the battery and connected equipment.
  • Cell Balancing: Automatically equalizes voltage across the 3 cells during charging, ensuring each cell charges uniformly—eliminating “weak cell” issues that reduce overall battery capacity and lifespan.

High Precision & Low Power Consumption
Equipped with high-sensitivity voltage detection chips, the board monitors each cell’s voltage with a precision of ±2mV, ensuring timely and accurate protection responses. Its ultra-low static current (<10μA) minimizes power drain when the battery pack is idle, preventing unnecessary capacity loss during storage or non-use. The board also features a fast recovery function: once the fault condition (e.g., overcurrent) is resolved, it resumes normal operation without manual reset—enhancing user convenience.

Wide Compatibility & Durable Design
This protection board supports 3S battery packs with capacities ranging from 1000mAh to 20000mAh, making it versatile for diverse applications. It is compatible with common lithium battery chemistries (Li-ion, Li-polymer, LiFePO4) and works seamlessly with standard chargers and discharge devices. Constructed with a flame-retardant PCB board and high-quality electronic components, it resists high temperatures (operating range: -20°C to 85°C) and mechanical stress, ensuring reliability in harsh environments (e.g., outdoor tools, industrial sensors).

Versatile Application Scenarios
Ideal for any 3S lithium battery-powered device, including:
  • Consumer electronics: 3S drone batteries, portable power banks, and high-power LED flashlights;
  • Industrial equipment: 3S electric tools (e.g., cordless drills), IoT sensor batteries, and small medical devices;
  • Recreational gear: 3S e-scooter auxiliary batteries, camping lanterns, and RC toy power packs.
