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.
