Company Profile

4S 14.8V Lithium-ion Battery PCB Circuit Protection Board for Mid-Power Devices

Calibrated to address the unique dynamics of 4-cell configurations,
the board delivers targeted protection aligned with 4S voltage
profiles and 10A discharge demands:
Overcharge Protection: Triggers at 3.75V (Li-ion)) per cell (total 15V for 4S packs),
instantly cutting charging current to prevent cell swelling or
thermal runaway—critical for 4S systems where voltage imbalance
across four cells can accelerate degradation.
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 performance in 10A mid-power operation.
10A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 10A (max discharge) or 30A (peak
surge), shielding the 4S pack and connected devices (e.g., cordless
mini-drills, portable LED work lights) from burnout during startup
or sustained use.
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 30% vs. unbalanced systems and maintains
consistent 10A discharge.
Ideal Application ScenariosThis board excels in 4S lithium devices requiring 10A peak
discharge:
Mid-Power Tools: 4S cordless screwdrivers, small angle grinders, or handheld
vacuums;
Portable Energy: 4S compact power stations (for charging laptops) or camping
lanterns;
Recreational Gear: 4S RC cars, drones (mid-sized models), or electric skateboards;
Industrial Aids: 4S IoT sensor arrays (moderate-power transmitters) or portable
medical devices (e.g., blood pressure monitors).
