High-Discharge, Controlled-Charge Power Management for 1S Battery Systems

The BAKTH-ITL0030050167-01 is a specialized 3-series (3S) Battery Management System (BMS) engineered for 11.1V lithium-ion and lithium-polymer battery packs. Featuring a unique dual-PCB configuration with two separate boards—Board A: 64×57.6×1.2mm and Board B: 55×37.6×1.2mm—this protection board offers unparalleled flexibility for installations where space constraints or form factor requirements demand distributed components. With a maximum continuous discharge current of 4A and maximum charge current of 3A, it delivers reliable power management for medium-power applications requiring asymmetric charge/discharge capabilities.

This innovative dual-board design allows for creative placement within battery compartments, enabling integration into devices where a single larger board cannot fit. Each board works in concert to provide comprehensive protection and cell balancing, ensuring optimal battery health, safety, and consistent performance throughout its service life.
