I have the silent charger which plugs directly to the wall. So there shouldn't be a problem with the powersource.
As for the NiMh, I put 3 packs of 4 cells in series (I connect them with wires, neg to positve), and charge all 12 cells the same time since the charger handles up to 14 cells.
I notice it never goes all the way to 4.1A, and after a while, goes to 2.3A or something.
Is everything ok? I have the temp probe on the cells and it does not kickoff any alarms for high temp...
