well. that was less than spectacular. it didn’t cause any problems for the printer but only went for 2 1/2 minutes. This APC unit last had a new battery in 2017 and was in use until last fall. so It might be a little better with a new unit but probably not by that much. I have some deep-cycle lead-acid batteries maybe I’ll hook one up and see if that works with it.
Heating the shop is a big deal so when I decided I was going to have more than one printer I made a sort of peninsula in the office with cabinets on a pedestal (inside a larger shop) that I installed a (camper) propane furnace under because it’s against an outside wall to vent. I can heat just the room with that in about 5 minutes and leave the rest of the shop at 10C or just above dew point to keep things from rusting. I also wanted the printers higher in the air, and this lifted the whole tabletop to about 48" I’d rather have the build plates closer to eye level.
So the little furnace runs off of 12v and I have a deep cycle there to runt hat for now and I wonder if I can use the APC unit to maintain that battery and provide backup for the printers? What makes a charger too small to charge a battery?
I have a converter unit coming to run the furnace from a supplier. so that will be 120v -->12v and provide 30 amp @ 12v for anything else. maybe LED lights?. It’ll be backed up with another 2 deep cycles I have.
