3S 100A 11.1V/12.6V Li-ion Protection Board with Equalization - High Current

This 3S 100A Protection Board is a heavy-duty Battery Management System (BMS) designed for 3-series Lithium-ion (NCM/Polymer) battery packs with a 3.7V nominal voltage. Delivering a massive 100A continuous discharge current, it is the ideal solution for 12V-class power applications requiring high density and high output, such as portable jump starters, high-power inverters, and custom DIY battery banks. The board features an integrated equalization circuit that ensures all three cells remain balanced during the charging process, maximizing the usable capacity and cycle life of the battery pack. With comprehensive safety protocols for overcharge, deep discharge, and short-circuit protection, this BMS ensures reliable operation even under extreme loads. Its compact design includes a dedicated sensing harness for precise 3-channel cell monitoring.

Key Features:

• Industrial-Grade 100A Discharge: Built with low-resistance MOSFETs and superior thermal dissipation for heavy-duty use.
• 3S 3.7V Optimized: Perfectly tuned for the 11.1V nominal and 12.6V peak voltage of lithium polymer cells.
• Integrated Voltage Equalization: Built-in balancing ensures cell uniformity for long-term pack health.
• Precision Safety Controls: Automatic cut-offs for over-voltage, under-voltage, and short-circuit conditions.
• Compact 3-Channel Design: Streamlined PCB layout for easy integration into tight battery enclosures.

Package Includes:

1 x 3S 100A 11.1V/12.6V Li-ion Protection Board with Equalization - High Current
