Higher Voltage Battery Tester?

[Athecal]

I am looking for a battery tester that can function like the zketech ebc-a20, but isn't limited to 30v. Ideally I would like the ability to measure capacity of battery packs up to 150v though I seriously doubt I would need to measure more than 100v. The ability to hook to a computer to get the pretty graphs and charts would be nice, not 100% necessary as long as I can just hook up the battery and walk away. Ideally I would like to spend less than $200 but if there is good equipment out there that costs a bit more I'd appreciate any information on equipment that can do this.

The Korad KEL103 DC loads are 120V 30A and not a lot of money.

Thanks for the new search term, I had never heard them called by this name before. Can find all kinds of good info now that I'm hip with the lingo as you youngsters say.

A DC load is often used to test power supplies etc but the KORAD unit does have a Battery Test option and I know they can be driven by a PC.

I am not sure how some of the small car battery testers work as they don't look like they have the ability to do a proper test.

But I know my uncle used to place a bulb/fan onto a battery and leave it for 1 hr and then measure the voltage before and after to see how much of a change there was. But He was only testing Tamiya RC car batteries.
