Eaton Powerware used to be Best, they made the very good FerrUps series.
Re: batteries, most all UPS's I've seen use various standard VRLA

replacing the batteries with 4 x 12V20AH Panasonic VRLA, which happens
to be the same size my motorcycle uses.

prices are very high, as are transportation costs.
