You can, but you need to use some additional charger. Your UPS charge batteries with 0,7A and you need now 10A @24V.

And check UPS construction and heatsinks, maybe he cant handle longer working time under higher loads, he is not designed for this, sometimes is needed to replace existing heatsinks with bigger and better.

Maybe one or several additional cooling fans. Keep in minds that you want to use device against manufacturers recommendetions.
