[RE-wrenches] Battery load tester purchase advice?

[RE Ellison]

Put one or two of the lightbulbs on a Rheostat and uses for fine control

I got lucky and found an old ohmite load bank real reasonable

Big and bulky you don't want to carry it far !

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.
