I have large battery packs, up to 60v@36Ah and output around 2000-3000w, which i would like to troubleshoot by loading them.
I'm thinking a variable rheostat + Battery Coulometer

I'm thinking of using the Battery Coulometer to capacity test them at of course something like 0.2C.
Is this a good idea or am I lost here?
