Oscar, I've been playing with the electrolysis quite a bit over the past 3 weeks with some quite good results, i'm planning on a bit of a write up but there's some pics and bits here

Mine was running anywhere between 5.5 and 9 amps and everything so far has taken no more that 24 hrs
I found its best to take the piece out and give it a quick pressure wash/hose/brush to remove the softened bits every 2 - 4 hrs or whenever your passing it.
Give me a shout if you got any questions, after a while of using the battery and charger I butchered an old 250w Atx PSU which worked just as well.
