Testing done on our test bench -- the standard hook-up is 1/0 wire from our battery bank to some reducers for 8 awg into the amp (few inches long). Makes testing amps faster so we don't have to fight with the wires. We used the 1/0 directly on some of the final testing. Not enough time in the day to do it both ways on all amps but we are very happy so far.
We'll do some in-vehicle testing soon with more electrical backing to really show what they can do.
All tests done with my Extech power clamp meter : 380976 - Single Phase/Three Phase 1000A AC Power Clamp Meter
We did not spend a ton of time shooting for the best figures -- we just sat down and tested each one back to back to get an idea of how the prototypes turned out. I am going to upgrade the power supply FETs for production as well for reference so expect them to be even a bit stronger.
