When running on battery, the load gets battery voltage. The load being
on battery (or charger) voltage seems to be the normal behavior for
these types of systems, so you'd have to really hunt for something that
does it differently.
You can hunt for something with a regulated output, or add a DC-DC
converter inline.
I haven't yet encountered a 48V device that didn't accept the whole
range from "batteries nearly dead" to "bulk charging", so I'm wondering
what that device is that needs >46v.
.....and I'm not a Traco lover. I'm kind of disappointed with it
actually. We must have bought 40 of those kits about 3 years ago, and
we now have 3 faulty BCM modules....they work except they no longer
charge batteries. I also received a whole box of them where the sticker
indicating which pin does what on the BCM was 100% backwards. By
following the sticker rather than the manual I ended up with the
temperature sensor (thermistor) connected to the reset switch. Didn't
break anything, but they units won't turn on that way.
At the time I needed something 48V at a higher wattage than Meanwell's
48V options, and Traco was suggested. I don't think I'd go there again.

Subject: [AFMUG] Traco BCM
Am I missing something or are the Traco BCM series not very usable in
the real world?
Meaning, the BCMU360 can only put out 45v (for a couple minutes, then
44v and change), when running on the battery. Not very usable with
some gear that requires about 46v to work properly. Add in voltage
drop on a long run and no-go.
I thought maybe the straight BCM 48v series would be better, but they
appear to have the same spec.
I have to think I am missing something or who the heck would they sell
these to? The industry standard is 48v (54v with float) so, outputting
44v sustained seems dumb.
Or is me 😊
Enlighten me please, you Traco lovers
