hmm, not sure about that connector PCB with what looks to be a 3D printed rain cover (are 3D prints even waterproof?!). Those look like JST connectors in the middle, which you generally only find on the inside of electronic products. They're not usually rated for the elements or mechanical strain and often have maximum mating cycles in the 10's.

Also, the supercapacitors look to be potted in the main housing. I thought capacitors needed some form of venting - especially large ones. Whilst they can last longer than batteries, they do eventually wear out and if they've been potted, it's not going to be an easy replacement.

Your concerns answered by Igaro:

1. The connectors have had no failures in over a year since release.
They were chosen partially for the ease of quick disconnect. This in
past experience is a major issue for damage to dynamo lights
specifically where wires are tidied too much or the rider drops the
wheel for packing in a box and forgets to disconnect the hub.

In the unlikely event a female side fails the rear PCB board is
replaceable, but it is more likely to be the male part of the
connector which goes first, and spare leads are available in this case.

2. The super-capacitors don't vent and are non-replaceable. They will
last the life-time of the product, which at equal usage is at least 10
times the life of any dynamo light containing a li-ion battery.
