Balance charging taking waaaaay too long

I am paralleling balance charging some Turnigy 4S 5Ah Hard Cases.
Its sitting at 0.2A, 16.77V and put in about 00189. It was set to 5A originally and 4S.
My 4 cells are 4.17, 4.17, 4.22, 4.17.

Before the cells were off by 0.07V, so I tried to discharge down to an even number where they were all close, then balance charge them up again. Of course I stopped and started the process but I think I will just leave it as is, because the delta V is a concern for me now. I still need to do another 2 batteries on the same pack, I thought my parallel board was messing something up, as some of the leads in the 4S connector on the parallel board are sticking more out then the rest because of "Mr. Sparky"

......See now its been 30 minutes, its dumped 00223 into it.

It does take a while to balance ...don't let the cells go beyond 4.20 if they do u run the risk of fire or explosion..
I charge mine at 2a
If the Batts r new 3.17 should b fine just don't over do the discharge in the model ..after a few cycles the Batts should start to balance out properly..

If you are parallel charging several (how many) 5Ah packs at only 5A total you'd expect it to take quite a while.
