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

The BAKTH-ITL0030050162-01 is a precision-engineered 3-series (3S) Battery Management System (BMS) designed for 11.1V lithium-ion and lithium-polymer battery packs. Featuring an slim form factor of just 53.9mm × 18.51mm × 1.0mm and symmetrical 5A maximum continuous charge and discharge current, this protection board delivers exceptional power management in an incredibly compact package. Its narrow, low-profile design makes it the ideal solution for space-constrained applications such as slim power tools, compact drones, and portable electronics where every millimeter of space matters.

This BMS integrates comprehensive protection features with precision cell balancing, ensuring optimal battery health, safety, and consistent performance throughout its service life. The ultra-thin 1.0mm profile allows for integration into devices where traditional thicker boards simply cannot fit.
