Charger for battery testing? (mander.xyz)

The tiny shitty fan on my Opus BT-C3100 (V1) is failing for the third time, sick of replacing it, so I want to buy a new charger.

I need something that can charge and measure the capacity of Ni-Mh and Li-Ion batteries up to 26650 in size. Was looking at the dragon vp4 plus which seems good, except it's max discharge is 500ma which is a bit pants since my old opus can do 1A. Is there anything better around the same price range?

You may want the SkyRC MC3000, which can discharge at up to 2A. It's expensive though ($100).

The nitecore UMs4 and UMs2 can test the resistance of a battery

I use a dedicated electronic load instead of relying on the really slow discharge rates in the charger: https://www.amazon.com/Electronic-Interface-Adjustable-Intelligent-Temperature/dp/B07HB3XK7L/
