 Drill approx. 6mm holes into the bottom part sides, one on each side, pull the wires through, then use flowable silicone to seal them. Finally, add a vinyl or tape protective film to avoid moisture from entering the inside.

+===== Conclusion =====
+In spite of XL7015 module being rated for 80V input, it's not recommended to use more than 65V on input side, as the QC of the chip itself is rather poor. I have had mine blow up nearing 70V.
+When testing battery packs, tungsten lamps are great as dummy loads. 12V with E27 thread are most common, but you can also find 24V or 48V. Make sure that the dummy load voltage rating matches your input voltage. Put 12V lamps in series to increase voltage rating.
