Thought I would pass this along

Off list Hi Dana Two of my contacts within EnerSys have just told me that they have never seen a 2 volt load tester. Steve Willy of Backwoods Solar showed me that if I took a 1200 watt 120 volt space hearer and cut the element into 10 equal lengths wired in parallel across buss bars I would have a 12 volt 1200 watt heater. I switched each element so I could increase or decrease load. I had to install muffin fans because the element would get much longer when hot than cold. Eventually I built several of these heaters into a small rolling tool box with a trimetric, trailer lights, and even a reading lamp so I could take readings without powering up the shop lights. I used it for load testing the surplus AGM batteries that we sold years ago. Funny, I can't remember what happened to that load bank. If you were to cut that same heating element into 60 equal lengths you would have a 2 volt 1200 watt heater. I found that the ribbon type of element was easier to work with vs. the coil type. These heaters are cheap in second hand stores..especially in the summer.

Off list Why not just make one yourself? Ohm's law and all that good stuff. You could even make a configurable load bank like the utility switch gear testers I've seen use. They all look homemade to me. Just label it clearly because if someone puts it on a 12v battery you could have a 1000 amp load tester for a second or two anyway.
