Looks like there might be some Aims on amazon used for reasonable price.
My backup for my pellet stove had 240 Ah of AGM batteries tied into a 700 watt UPS. the load running the blower and auger was 120W running the blower and another 55 or so for the auger. I ran it once for 5+ hours on battery and it was above 50%.
