I may be misunderstanding this as some may think this is my build or design which it isn't. No doubts or confusion about that. Basically you posted it first so I guess everyone is replying to your thread JST connectors are not meant for end usage, like I said earlier they are great for PCB designs. JSTs are not convenient like USBs and it's not about usage cycle, it's about the usage. Just a layman analogy - it's like using a hex wrench to open a philips head.
