WIZPoE-P1 - PoE power module 5V

This step-down converter module allows you to reduce the voltage from 6-60V to a stable 6V at a current of up to 11A. Its high efficiency of up to 95% and low power losses make it ideal for applications requiring high current and stable power. The device features built-in overcurrent, thermal, and reverse connection protection, as well as a soft-start function and a Power Good indication. Pololu 5673

BMS system for four Li-Ion cells with a voltage of 16,8 V. It has the function of charging with balancer, discharging and over-discharge protection. The cells can be charged with continuous current up to 60 A and discharged with current up to 80 A

A passive on/off power switch that provides control and feedback functions, allowing you to start and safely shut down your system with short presses of the button, while a long press forces the power off. The Mk2 version, based on the 74LVC1G175 D-type flip-flop digital design, eliminates the problems of component tolerance and temperature variation, and also offers additional improvements such as a 2A self-resetting fuse, LED indicators, and the ability to connect a larger external button.
