I am sure there are other power supplies out there that could go to 80 amps but I am working with supplies that go to 47 so I am trying to figure out the best configuration given that.
I'll have to think about that one. Here's the challenge. Charging a 6s pack at 40 amps, you'll be pulling roughly 30 amps from the supply. 47amps is a bit overkill in that scenario. But with a 50v supply you'd only be pulling about 23 amps per channel, or 46 amps total. It would seem four supplies would be a better fit than 6 supplies unless you want the overhead or need to charge at 7s or 8s.
I have four of the DSP-600PBs. When I get time, I'll set up the config and give it a test run.
