They are very sweet and neat. And you can make a grid charger for £50!

In fact looking at them they could be easily installed in the IPU compartment with just a mains power input socket to the outside world.

But doing so would make monitoring and adjusting the output voltage and current difficult. I suppose that these things could be set before installing, but would that be sufficient over the long run? Would having the grid charger external be a better design?

I encourage you to consider this as a replacement for your single-psu design for which you were asking for potential customers.

Wouldn't 570ma lead to excessive heating? Do these psu's have an adjustable constant current setting that could be set in the 250 - 300 ma range that those in the know have been suggesting? I suppose an ammeter would need to be part of the grid charger package to allow one to set the current level.
I'm looking forward to hearing your test results with these psu's.
