These tiny little 48V 25watt psus have arrived!
They are very sweet and neat. And you can make a grid charger for £50!
25Watt 48V / 0.57A Single Output Power Supply Heng Fu on eBay (end time 03-Jul-09 18:19:19 BST)
They have a supplier in US and you never know may be a discount for quantity. (Note I've e-mailed the UK supplier about a bulk purchase) See previous post on this thread for the US supplier. I suggest someone looks at that possibility over there.
Ron you could knock them up into grid chargers and flog them with your recon batteries.
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.
I tested one and it will go from 40-54.5V no load.
Three makes that 163.5V Not quite high enough but four gives us a very nice range.
I havent tried them in series yet, but four would fit in a nice neat case and they look a good but as yet untested option.
With a 570ma ish output the re-balance grid charge could be done in one night easily.
