Off Topic - Battery Chargers and RFI

I realize this is way off topic but I thought I'd ask since everyone here has a Flex with a great panadapter that has the ability to detect all sorts of locally generated interference.

I like to run my radio equipment off of a 12v battery system consisting of four 6v golf cart batteries wired in series parallel.   I am looking for a fully automatic battery charger that does not produce a bunch of RFI. 

Does anyone here presently power their station from a battery bank?  If so, what are you using to charge it with and how RFI quiet is it?

Hi Norm:

For the past year I've used the West Mountain Radio PWRGate with good luck noise and function. I see nothing on the waterfall when running with the power supply on or off.

On one side I use an Alinco DM33OMV-32A switching power supply and on the other side is a marine battery. 

I used an Astron RS-50 before the Alinco and oddly enough that did generate a bit of noise. I'll bet the Astron could use some TLC as I understand that there is a bit of a QA issue with the build. The other thing about the Astron is that big old transformer hummed regardless of power draw.

You might want to consider the West Mountain Radio Super PWRGate or soon to be shipped Epic PWRGate.  The PWRGate includes a charge controller that uses an external 12v supply.  Although designed to switch from a primary 12V supply to batteries for backup, if you are running your radio primarily from the batteries then the 12 V supply only needs to be large enough to provide the charging current.  With the lower current requirement, then you can use a linear supply and avoid the whole switching supply issue.
