8S 29.6V 60A Li-ion Battery BMS PCB Module with OCP for Power Tool Industrial Equipment
Designed for high-performance 8-cell series (8S) lithium battery packs—compatible with Li-ion, Li-polymer, and LiFePO4 chemistries—this protection board stands out with adjustable overcurrent protection (60A±5A for both charge and discharge) and a 60A maximum discharge current. Optimized for medium-high voltage systems (nominal 29.6V for Li-ion, 25.6V for LiFePO4), it combines flexible current regulation with robust safety safeguards, making it ideal for heavy-duty power tools, electric mobility gear, and industrial energy storage systems that demand customizable protection and high-current reliability.
8S-Specific Protection & 60A High-Current Safeguards
Calibrated to address the unique dynamics of 8-cell packs and 60A extreme discharge, the board provides targeted protection to mitigate high-power risks:
Overcharge Protection: Triggers at 3.65V (Li-ion) per cell (total 29.2V for 8S packs), instantly cutting charging current to prevent cell swelling, electrolyte breakdown, or thermal runaway—critical for 8S systems where voltage imbalance across 8 cells amplifies degradation under high-current stress.
Undervoltage Protection: Shuts down discharge at 2.5V (Li-ion) per cell (total 20.0V for 8S packs), avoiding irreversible capacity loss from deep discharge, especially during 60A sustained high-load operation (e.g., electric vehicle acceleration or industrial tool heavy use).
60A Overcurrent & Short-Circuit Protection: Leverages high-power MOSFETs to block currents exceeding 60A (max discharge) or 180A (peak surge), shielding the 8S pack and connected devices from burnout, overheating, or fire risks during extreme use or accidental short circuits.
8-Cell Active Balancing: Automatically equalizes voltage across all 8 cells during charging, eliminating uneven charge distribution—a persistent challenge in high-cell-count, high-current packs. This feature extends battery lifespan by up to 40% vs. unbalanced systems and maintains consistent 60A discharge performance over cycles.
This adjustable high-current protection board excels in 8S devices requiring tailored overcurrent control:
- Heavy-duty power tools: 8S cordless jackhammers, large angle grinders, or concrete cutters.
- Electric mobility: 8S high-speed e-scooters, mini e-bikes, or off-road utility vehicles.
- Industrial energy storage: Compact 8S power stations for job sites (powering multiple high-wattage tools) or emergency backup systems.
- Specialized equipment: High-performance RC vehicles, small electric forklifts, or solar energy storage setups.
