Suggestion on pixhawk cube power module insulation

Hello hex manufacturers

Im using pixhawk cube genuine power module(not counterfeit) and tbs discovery frame.

I experienced some accident 2 days ago so I suggest something on cube power module

I was using well this power module more than 2 months but suddenly this power module generated explosion sound when I connect the battery.

Originally, power module is considered to be insulated because it is wrapped in vinyl.

but I guess that that power module caused a short circuit by its sharp lead solder shape protruding outward so small(even can’t catch by eye).

sharp lead shape touched carbon frame and caused short circuit.

luckily, I found no other problem than explosion sound, this power module works great now but It is the potential hazard so I wrapped my power module with insulation tape.

I hope this problem is not generated in the future product
