Advanced Rectangle 4S 14.8V 15A Lithium Battery BMS with Balancing Function 0



The ITL0040150008-01 is a high-performance, mid-power protection board exclusively engineered for 4-cell series (4S) lithium battery packs—compatible with Li-ion, Li-polymer, and LiFePO4 chemistries—with a maximum discharge current of 15A. Tailored for medium-voltage (nominal 14.8V for Li-ion, 12.8V for LiFePO4) and moderate-to-high load applications, it balances robust safety controls with responsive 15A current handling, making it ideal for mid-power electric tools, recreational gear, and compact energy storage units.

4S-Specific Protection & 15A High-Current Safeguards
Calibrated to address the unique dynamics of 4-cell configurations, the board delivers targeted protection aligned with 4S voltage profiles and 15A discharge demands:
  • Overcharge Protection: Triggers at 4.25V (Li-ion) per cell (total 17.0V for 4S packs), instantly cutting charging current to prevent cell swelling, electrolyte breakdown, or thermal runaway—critical for 4S systems where voltage imbalance across four cells amplifies performance degradation risks.
  • Undervoltage Protection: Shuts down discharge at 2.5V (Li-ion) per cell (total 10.0V for 4S packs), avoiding irreversible capacity loss from "weak cells" that compromise stability during 15A high-load operation (e.g., electric tool startup).
  • 15A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 15A (max discharge) or 45A (peak surge), shielding the 4S pack and connected devices (e.g., cordless angle grinders, mid-sized drones) from burnout during sustained use or accidental short circuits.
  • 4-Cell Active Balancing: Automatically equalizes voltage across all four cells during charging, eliminating uneven charge distribution—a common issue in 4S packs that reduces runtime and lifespan. This feature extends battery life by up to 35% compared to unbalanced systems and maintains consistent 15A discharge performance.

 

Ideal Application Scenarios​
This board is tailored for 4S lithium devices requiring 15A peak discharge:​
  • Mid-Power Tools: 4S cordless drills, small angle grinders, or handheld vacuums (14.8V Li-ion systems);​
  • Recreational Gear: 4S mid-sized drones (for extended flight time), RC cars/boats (high-torque performance), or electric skateboards;​
  • Portable Energy: 4S compact power stations (for charging laptops or small appliances) or camping LED work lights;​
  • Industrial Aids: 4S IoT sensor arrays (moderate-power long-range transmitters) or portable medical devices (e.g., small oxygen concentrators).
