Default Lm4702 on pure dc power

Im working on a Lm4702 amp with mosfet outputs that runs on pure dc power from batteries.They thew out some UPS units at work,they each have 10 12 volt batteries in them that give me +60 and -60 if you put a common point at battery number 5 and 6.When using it to listen to audio you turn off the UPS after your done you turn the UPS on to charge the batteries or I might make a battery charger.I wonder if the sound will improve with dc power vs transformer and the batteries can supply larger peak current.Anyone have any thoughts on this idea

Battery power is good.
Very good in compare.

If I had the opportunity, to get +/-60 Volt, or even 50% of this,
I would gladly use it instead of Mains AC+Transformer.

But most of us can not find more
than +/- 12 Volt or +/- 24 V DC battery supplying.
And we have not all that it takes to charge so big batteries
with enough current and voltage.

Be Happy!
Such a supply you describe, is almost ideal.
If your batteries are big enough.

There are systems for powering CARS and run them on electricity.
And if HEAVY CARS can be run by Battery systems, then many things can.
But all such new techniques are still very expensive.
Maybe in future all will run Power Amplifier
using similar Accumulator, Rechargeable Cells.

Our Power Supply will be Charged while we are asleep ...

lineup charged every day by food
