I was thinking about using a UPS as a power supply for an amplifier.
The UPS is rated at over 2KW and uses 48 volts on the DC bus. I have
tried powering an amp directly from the batteries and it seems to work
OK. Battery pack is rate at 20 amp/hr. The inverter side of the UPS is
dead but the charger side is still functional. The plan is to remove
the inverter circuit completely. Can anyone think of anything wrong
with doing this.

It should work OK. The only problem I see is if the charger is not
regulated. It probably is to keep the batteries from overcharging. I
bet that baby is heavy.
I have found a 48 volt 20 amp supply that I use with my EB104 Amp
that is about 8 lbs. The Amp itself is about 5 lbs., so I have 600
watts out in under 15 lbs. or .4 oz./watt.
The power supply is less than $300 USD including shipping. If you
want more details, let me know.
