Description
BAKTH-ITL0040100033-01 7A Charge 8A Discharge 4S Li-ion Battery BMS Protection Board
The BAKTH-ITL0040100033-01 is a high-current, high-precision 4S lithium battery protection board professionally designed for 4-series lithium-ion battery packs (14.8V nominal, 16.8V full charge voltage). Featuring accurate current threshold control and stable load capacity, it supports a maximum continuous discharge current of 8A and a maximum continuous charge current of 7A, with precise over-current protection thresholds (9.8A-10.2A discharge overcurrent & 8.5A-9.5A charge overcurrent). Integrated with full safety protection and passive cell balancing functions, this BMS board ensures safe, stable and long-cycle operation for medium-power 4S lithium battery packs in industrial, portable and DIY power equipment.
Core Advantages
  • Full-Suite Safety Protection: Complete protection against overcharge, over-discharge, overcurrent, short circuit, and over-temperature, maximizing battery safety and lifespan.
  • Precision Current Control: It supports 8A steady discharge and 7A steady continuous charging, with strict over-current trigger ranges, effectively avoiding board burnout and battery damage caused by current overload.
  • Cell Balancing for Longer Life: Built-in cell balancing function eliminates cell inconsistency, ensuring each 4S cell charges and discharges uniformly, improving battery pack efficiency and extending its overall service life.
  • Flexible Customization: Adjustable overcurrent thresholds and OEM/ODM options to match your specific product requirements.
