3S 12.6V Li-ion BMS Protection Board with high-current MOSFETs, designed for 3-cell lithium-ion battery packs. Provides battery protection against overcharge, over-discharge, over-current and short circuit conditions. Board size: 90 × 54 mm.

3S 12.6V 40A–80A Li-ion BMS Protection Board

The JBD-BP055006 V1.4 is a high-current 3S Battery Management System (BMS) designed for 3-cell lithium-ion battery packs.

The board is suitable for applications requiring battery protection and controlled charging/discharging of a 3S Li-ion pack with a nominal voltage of 11.1V and a maximum charging voltage of 12.6V.

It uses multiple power MOSFETs to handle high-current battery applications and includes protection functions intended to help protect the battery pack from abnormal operating conditions.

The compact 90 × 54 mm PCB makes it suitable for battery packs, portable equipment, DIY battery projects, electronic devices, backup power systems and other lithium-ion applications.
