The small PowerPole is already a marginal connector for high-current DC

I do use the presets (I/II). I would prefer the idea of fixed presets

Farnell also do them in the UK. I have also seen many available via Ebay.
I would not worry too much about them, they have their weaknesses,
especially their tendency to come apart from each other because of the lack
of a locking mechanism, but at least they are a standard now.

You do still get a 4ppm improvement so why wouldn't they take money for the
