Help me to build a Dc ups

[Dpunkr1]

custom UPS for your Lenovo ThinkCentre M72p using 2x IRF4950 MOSFETs and a 12V 30Ah LiFePO4 battery. The design takes your existing 19V grid power adapter, steps it down to 14.2V via buck converter to safely charge the battery, and uses a boost converter to maintain 19V output to the PC during outages. The MOSFETs provide automatic, seamless switching between grid-charged bus and battery power with minimal loss.

I think you posted the wrong attachment. The transistor pinout is more or lesl useless without an accompanying schematic diagram.

Hi, harald,,this is the mosfet I got to make the circuit with,,please help

How are we supposed to help when you don't show a schematic of your circuit?
