How to make it work?

[Namso]

Hi. I'm wondering how could I get this to power on? I bought a module before with the wires and I connected it to my 18650 battery and worked fine but then the wires came off due to the bad soldering. So I'm asking how could I possibly get this to work?

Loose wires equal dead diodes...I hope you didn't suffer this fate.
