Yeah, I think I'm just going with the BCMU for new stuff that requires
>100W. There's pros and cons to the 12V and DC-DC conversion, but I'm
not really concerned about that in most cases.

Looks sweet. Price? Anyone used one?

The install instructions for it also mention a battery test, but like
the other BCM units there's minimal information on how the test operates. I
asked Traco for more information on the test it does. Maybe it's the same
process as the TLB-BC I mentioned earlier today, just not documented as
such.
If that's the case, the BCMU seems like a slam dunk.

Am I understanding that unit correctly? It has a step-up converter from
the battery, so unlike the BCM-12/24/48, the output will always be
regulated 24 or 48 volts, not battery voltage? Also that it only needs a
12V battery? And can work with any DC power supply since unlike the BCM it
doesn’t control the power supply output voltage?

This is where the BCMU-360 makes sense, 24 or 48v in one unit.

I believe the BCM does have a battery test, maybe not as fancy.
My reaction is 60W is kind of low, plus I can use 3 different sizes of TSP
from 90 to 360W with the same BCM or alone as just a power supply or add
the BCM later. And if it fails, I only have to replace the failed unit.
And if the BCM fails, the site can run on just the TSP if I don’t have a
spare. And there is a 48V version of the BCM. So it seems more flexible.

Has anyone looked at the Traco TBL-BC before? It seems to do a lot
things other than basic battery charging and even temperature compensation.
It's not all that big, but may be good for repeater sites. Seems to be
about the same cost for a bigger power supply and regular BCM as this guy,
but the alternative wouldn't have the battery testing system.
