High-Stability PCB 10S Lithium Battery Protection Board for 10S Li-ion Battery Packs

High-Stability PCB 10S Lithium Battery Protection Board for 10S Li-ion Battery Packs

• The BAKTH-010S020A-0048-01 is a model-specific, high-voltage 10S lithium battery protection board, engineered exclusively to safeguard 10-cell series (10S) lithium battery packs—covering Li-ion, Li-polymer, and LiFePO4 chemistries. Its model code encodes critical performance traits: “010S” confirms compatibility with 10-series cells, while “020A” denotes a 20A continuous current rating, making it ideal for high-voltage (nominal 36V for Li-ion, 32V for LiFePO4), medium-to-high power devices that demand robust safety and stable energy delivery.

  10S-Tailored Protection for High-Voltage Safety​

  Optimized for 10S battery configurations, this board addresses the unique risks of multi-cell high-voltage packs with calibrated safeguards for 10 individual cells:​

  • Overcharge Protection: Triggers when any cell exceeds 4.25V (Li-ion), instantly cutting off charging current to prevent cell swelling, electrolyte breakdown, or thermal runaway—critical for 10S packs where cumulative voltage amplifies overcharge hazards.​

  • Undervoltage Protection: Shuts down discharge if a cell drops below 2.7V (Li-ion), avoiding permanent capacity loss caused by “weak cells” that can disable the entire 10S system.​

  • Overcurrent & Short-Circuit Protection: Blocks currents exceeding 20A (continuous) or 60A (peak), shielding the 10S pack and connected devices from burnout during high-load operation (e.g., heavy-duty tool startups) or accidental short circuits.​

  • 10-Cell Balancing: Automatically equalizes voltage across all 10 cells during charging, eliminating uneven charge distribution—a major pain point in high-cell-count packs—and ensuring each cell operates at peak efficiency, extending the 10S pack’s lifespan by up to 40% compared to unbalanced systems.

  Ideal Application Scenarios

  This 10S protection board is tailored for high-voltage, medium-to-high power devices:

  • Heavy-Duty Power Tools: 10S cordless circular saws, jackhammers, or impact wrenches requiring 36V stable power;

  • Medium-Scale Energy Storage: 10S portable power stations for RVs, camping, or home backup (powering small appliances);

  • Light Mobility: 10S electric scooters, small e-bikes, or off-road RC vehicles (e.g., 1/8-scale trucks);

  • Industrial & Medical: 10S IoT sensor arrays (high-power long-range transmission), portable oxygen concentrators, or small-scale factory automation tools.
