Product Description
BAKTH-0016S030A-0029-01 15S Lithium Battery Overcharge/Overdischarge/Short-Circuit Protection Board for High-Power Devices
The BAKTH-0016S030A-0029-01 is a high-voltage, high-reliability protection board optimized exclusively for 15-cell series (15S) lithium battery packs—covering Li-ion, Li-polymer, and LiFePO4 chemistries—with a maximum discharge current of 30A. While its model code includes “0016S” (indicating broad design compatibility), it is fine-tuned for 15S configurations (nominal voltage: 55.5V for Li-ion, 48V for LiFePO4), and the “030A” designation aligns with its 30A high-current handling capability. This makes it an ideal choice for medium-power, high-voltage devices such as industrial tools, electric mobility gear, and mid-scale energy storage systems.
15S-Specific Protection & 30A High-Current Safeguards
Calibrated to mitigate the unique risks of 15-cell high-voltage packs, the board delivers targeted protection tailored to 15S dynamics and 30A discharge demands:
Overcharge Protection: Triggers at 3.9V (Li-ion) per cell, instantly cutting charging current to prevent thermal runaway—critical for 15S packs where cumulative voltage (up to 63.75V fully charged for Li-ion) amplifies overcharge hazards.
Undervoltage Protection: Shuts down discharge at 2.0V (Li-ion) per cell, avoiding irreversible capacity loss from “weak cells” that can disable the entire 15S system, especially during 30A high-load operation.
30A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 30A (max discharge) or 90A (peak surge), shielding the 15S pack and connected devices (e.g., heavy-duty cordless drills, mid-range e-scooters) from burnout during startup or sustained high-power use.
15-Cell Active Balancing: Automatically equalizes voltage across all 15 cells during charging, eliminating uneven charge distribution—a major challenge in high-cell-count packs. This extends the 15S pack’s lifespan by up to 35% compared to unbalanced systems and maintains consistent 30A discharge performance.
Technical Precision for Reliable Operation
Equipped with high-sensitivity voltage detection chips (±2mV accuracy), the board monitors each of the 15 cells in real time, ensuring timely responses even during 30A discharge spikes. Its ultra-low static current (<10μA) minimizes idle power drain, preserving 15S pack capacity during storage—ideal for backup energy storage or infrequently used industrial equipment. It also features an auto-recovery function: after resolving temporary faults (e.g., momentary overload), it resumes operation without manual reset, enhancing usability for both professional and consumer scenarios.
Durable Design for Harsh Environments
Constructed with a flame-retardant FR-4 PCB (UL94 V-0 rated) and industrial-grade MOSFETs (optimized for 30A current handling), the board withstands extreme temperatures (-20°C to 85°C) and mechanical vibration. This durability makes it suitable for harsh settings such as construction sites, outdoor mobility use, or workshop environments. It supports 15S packs with capacities from 4000mAh to 45000mAh and is fully compatible with standard 15S chargers, as well as all mainstream lithium chemistries—eliminating the need for multiple protection boards.
Ideal Application Scenarios
This board is tailored for 15S lithium devices requiring 30A peak discharge:
Industrial Tools: 15S cordless impact wrenches, large-angle grinders, or 55.5V (Li-ion) concrete drills.
Electric Mobility: 15S mid-range electric scooters, small e-bikes, or off-road utility vehicles.
Portable Energy Storage: 15S compact power stations for job sites (powering hand tools) or camping (running small appliances like mini-fridges).
Industrial IoT: 15S high-power sensor arrays (long-range data transmitters) or small automated machinery.
