Travis, What is the Manuf, Model of these gel cels, and where do you get them. additionally, is this a simple setup, just tie them in to the existing UPS. I have a Minuteman online 2000VA, only 2 batteries and they are small. Can I set these Batts in the Equip Bldg in a "pan" and let them exist w/ active equip? I'm in Michigan and it gets fairly cold in Winter.
