Newbie question about DC-DC Setp-up

[otolosa]

Hi everyone

this maybe very simple.....but i wanted to be sure doing it the right way.

Im planing to use a DC-DC step-up converter so i can use less batterys on my portable project but not sure what is the best way to connect it to power source and breadboard (initially) and PCB (final product)

It has 2 holes/plates for input (Vin/gnd) and 2 for output...no headers...

Should I solder battery holder cables to input and solder 2 cables for output?...use headers?

THanks for your help

Unless you plan to move it around, soldering is probably best. Those headers/duponts tends to slip out when you least want it.
