I have a CC-400 400W discharger and CBA-II battery tester. Runs on windows.
I know I could use one of those powerlab 8 and a couple of the CC-400's. You would run the powerlab 8, it would trigger the CC-400's as soon as it would start discharging and then the powerlab would stop once it gets a certain level and charges again. Not sure the limits, or why you'd ever want to go to 1V.
yes, there's stuff out there. There's also a lot of stuff that'l do discharging, not a ton will do cycling.
I'd be interested in something that does more amps though, so you could test some of those 180Ah+ lifepo4 cells to see if they really meet spec.
