Thanks to everyone for their input, it really clarified how to get the data Trojan is looking for. I am going to go with what we have in stock as a "Trojan Approved" load tester is out of my price range, and the reasonably priced auto parts store ones hit you 100+ amps plus as they are trying to test CCA, not SOC. I have a voltage logging USB unit along with a current logger and CT. We'll use a small inverter and switchable AC light bulbs for load so that it stays constant at the 25A Trojan wants to see, and in the future we'll be able to adjust it for amperage by switching in and out more light bulbs.
