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.

Bear in mind that even with light use, the batteries will eventually
have to be replaced. APC, for example, rates their SOHO UPS devices
with replaceable batteries at 2-3 years between change-ups.

However, this is an excellent way of maintaining a decent shack when the
lights go out.
