Hi, i´m new to the uav world and i want to build my first one. I been reading and doing some research about what power module i should use but i don´t know which features are a MUST. if you could help me ill be very thankful.

As a beginner, select a power module that is rated for your max voltage and current with power and signal cables matching your battery, aircraft, and flight controller. Should your needs become more demanding, you might want a power module with more accurate current sensing. We have soem good quality power modules with XT60 and JST-GH connectors at www.KashmirWorldFoundation.org.

Thanks! I´ll check them out

Take a look the Power Modules that has mRobotics manufacturers in the USA, excellent quality. Especially check out the one with the hall sensor, which makes it extremely accurate across the entire current range. (mRo Hall Sens Power module ACSP7)

As the conversation started from the perspective of "a beginner," I had avoided mention of Hall sensors and other special features. For most applications a low cost power module works just fine. The voltage and current sensing for these low cost power modules can be calibrated to achieve an accuracy sufficient for most applications. The mRo power module is a step up in quality and performance at a price comparable to many lower quality power modules. For larger, higher voltage planes we often use Mauch power modules (https://www.mauch-electronic.com/) They also have Hall sensors with an architecture that works well at high voltage and current.
