The battery tester we built, controlled by an EDU RC controller, can test with varying loads. One can program any desired load profile from 0 to 63 amps, in steps of 1 amp, and simulate a match if you want (with current limited at 63 amps). One could upgrade to support higher currents if one wanted. We have only used the load tester for a fixed load, however, to certify the capacity of our batteries against the published curves. It pays to identify any batteries that are not measuring up and relegate them to practice use, or single match use.
