[Elecraft] Looking for a couple of good smart chargers

[Greg Troxel]

I have used two different units of the Battery Tender 6A charger model.
One failed (after many years) leading to overvoltage.  The other
generates huge amounts of RFI especially on 20m.   They certainly seem
smostly ok, with those caveats.

I recently got an Optimate 3+, which is only 600 mA but claims to do
desulphating.  Notably, when going into float mode, it float charges for
30m and then lets the battery sit for 30m, which seems nicer to the
battery, and also lets it detect more cases of batteries that are not
ok.  RFI-wise it seems not as bad but hardly ok.

I also have a gensun gv-5 MPPT solar controller.  It and a panel makes
an RFI-quiet charger, at least on some days.   It floats at 13.5V, nd
does equalization at 14.2ish once every 7 days.
