Any recommendations on a DC-DC converter that does not squeal like
this Todd converter?? Silence is golden, and the primary issue here.
Also, would like one that can handle up to 156 volts, as I will be
adding batteries to the next pack after this one fails (hopefully some
time in the distant future!).

Am only speaking from experience:
DCP: only 35 amps; has a bipolar 12V out for the
E-meter.
Belktronix: 50-60 amps.
Both were reliable for me and no squeal.
peace

Would you still drive your car if the tailpipe came out of the steering wheel? Are you saving any gas for your kids?

Also speaking from limited experiance.

I have an The IOTA DLS-220-55. It is quiet and uses very little current
when battery is charged.
Although it is an AC unit it works on DC. I was worried because I have a
288V nominal pack and end of charge is 354 and equalize can go as high
as 400.
(I meant to disconnect it for the equalize but forgot.)

220AC is like 317 peak and they usually run a 370V dc link voltage. This
unit hasn't browned out with as low as 240V dips.

I suspect the DLS 45 would be more appropriate as it operates off of
120V (their site is a little misleading) which is 170V dc peak. Others
on this list can give a picture of what voltage range packs but happen
to give a test point at 108VAC which by happenstance would be 153VDC the
end of charge of 192ish would be above the 170 Volt peak, but there is
usually some headroom. It sounds like it would work well on a 156V pack,
Anyone using on 156V pack?
