EOS0610i charging too slow

[yuri]

Hi, I´m charging my 2 Zippy 6s 4000mAh packs with my EOS0610i, have set of course it to charge at 4 Amps, and it takes to charge each one of them up to 110 minutes, since it´s always charging at around 2-3 amps, it never gets up to 4 amps. I remember when I used to charge my maxamps with my multiplex charger and the lba10 balancer that it was always taking it up to the amps I had marked, but now it won´t happen... Any ideas?

Maybe it´s the power supply I´m using at home, it´s only 12V 7,5A and it´s a small one but I´ve had the same issue when charging with my 1:1 car battery, and that´s a big one! BTW I´m always changing the config according to the power supply I´m using.
