3S 8A 11.1V Lithium Battery Charger Protection Board Module for 3PCS 18650 Li-ion Battery Cell Charging BMS 10.8V 12V 12.6V

The ITL0030100039-01 is a precision-engineered protection board designed exclusively for 3-cell series (3S) lithium battery packs—supporting Li-ion, Li-polymer, and LiFePO4 chemistries—with a maximum discharge current of 8A. Tailored for low-to-medium power, mid-voltage applications (nominal 11.1V for Li-ion), it balances reliable safety safeguards with efficient current handling, making it ideal for consumer electronics, small IoT devices, and light-duty portable tools.

3S-Specific Protection & 8A Current Safeguards

Calibrated to address the unique needs of 3-cell configurations, the board delivers targeted protection optimized for 3S voltage dynamics and 8A discharge demands: 

  • Overcharge Protection: Triggers at 4.23V (Li-ion) per cell (total 12.7V for 3S packs), cutting off charging current to prevent cell swelling or thermal runaway—critical for 3S systems where voltage imbalance between three cells can accelerate degradation.
  • Undervoltage Protection: Shuts down discharge at 2.8V (Li-ion) per cell (total 8.4V for 3S packs), avoiding irreversible capacity loss from "weak cells" that often affect multi-cell packs during sustained 8A operation.
  • 8A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 8A (max discharge) or 24A (peak surge), shielding the 3S pack and connected devices (e.g., small LED work lights, portable sensors) from burnout during startup or continuous use.
  • 3-Cell Balancing: Automatically equalizes voltage across all three cells during charging, eliminating uneven charge distribution—a common issue in 3S packs. This extends battery lifespan by up to 25% vs. unbalanced systems and maintains steady 8A discharge performance.


Ideal Application Scenarios

This board is tailored for 3S lithium devices requiring 8A peak discharge:

  • Consumer Electronics: 3S portable speakers, handheld game consoles, or small power banks.
  • Light-Duty Tools: 3S cordless mini-drills, LED work lights, or handheld vacuums.
  • IoT & Sensors: 3S Bluetooth beacons, environmental monitors, or asset trackers.
  • Recreational Gear: 3S RC toys (small cars, drones) or camping lanterns.
