Low resistant clamp/holder for 18650 cells?

I’ve recently gotten a CBA IV, so it is time for me to do some tests on some cells that I have sitting around!

I do have on hand some of those $0.99 eBay cheapie 18650 holders, but the wires that came soldered with them are incredibly thin, and the whole thing just looks poor in general, so I am feeling concerned that it might affect test results.

Is there some good quality clamp/holder of sorts that you’ve used before for doing similar type of testing?

Thanks!

What is a Hobby Charger - check the section “How to connect the cells”, easiest one is using Luminous DIY holder, but it’s hard to find them for sale anymore.

Does anyone know what is this clamp that HKJ is using?

The clamp on the picture is an Irwin, the clamps I am using in my current battery test does not have a name.

The wire connection is DIY. I drilled a hole through the top and bottom of the clamp and then used a screw and some brass nuts. Next time around I replaced the brass nuts with a piece of a copper rod and added separate wires for current and measurement (My current equipment can handle that).
