High Performance 8S 29.6V 15A Li-ion Battery BMS Protection Board for Power Tool E-bike
The ITL0080050065-01 is a high-reliability protection board exclusively engineered for 8-cell series (8S) lithium battery packs—compatible with Li-ion, Li-polymer, and LiFePO4 chemistries—boasting a maximum discharge current of 15A. Tailored for medium-high voltage applications (nominal 29.6V for Li-ion, 25.6V for LiFePO4), it balances robust safety controls with responsive high-current handling, making it an ideal choice for mid-power electric tools, light mobility gear, and compact energy storage systems that demand stable 8S power protection.
8S-Specific Protection & 15A High-Current Safeguards
Calibrated to address the unique dynamics of 8-cell configurations, the board delivers targeted protection aligned with 8S voltage profiles and 15A discharge demands:
Overcharge Protection: Triggers at 4.25V (Li-ion) per cell (total 34.0V for 8S packs), instantly cutting charging current to prevent cell swelling, electrolyte breakdown, or thermal runaway—critical for 8S systems where voltage imbalance across eight cells amplifies degradation risks.
Undervoltage Protection: Shuts down discharge at 2.83V (Li-ion) per cell (total 22.64V for 8S packs), avoiding irreversible capacity loss from "weak cells" that compromise stability during 15A high-load operation (e.g., electric scooter startup or tool acceleration).
15A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 15A (max discharge) or 45A (peak surge), shielding the 8S pack and connected devices (e.g., cordless grinders, mid-range e-scooters) from burnout during sustained use or accidental short circuits.
8-Cell Active Balancing: Automatically equalizes voltage across all eight cells during charging, eliminating uneven charge distribution—a persistent challenge in high-cell-count packs. This feature extends battery lifespan by up to 35% compared to unbalanced systems and maintains consistent 15A discharge performance.
Ideal Application Scenarios
This board is tailored for 8S lithium devices requiring 15A peak discharge:
- Mid-Power Tools: 8S cordless drills, angle grinders, or concrete cutters (29.6V Li-ion/25.6V LiFePO4 systems);
- Light Mobility: 8S electric scooters (mid-range models), mini e-bikes, or off-road utility vehicles;
- Portable Energy Storage: 8S compact power stations (for charging laptops, small appliances) or camping LED work lights;
- Industrial Aids: 8S IoT sensor arrays (moderate-power long-range transmitters) or small automated machinery.
