- You are running 2 hyperion 1420i chargers on separate isolated power supplies (MW in parallel).
Yes, that is right. Two MWs per 1420i.

Yes, they are basically permanently connected in series on the bike. I bring out one 18-pin AMP VAL-U-LOK connector for each 12s3p pack. Each of these connectors use 14-pins for the balance wires, and two-each for the main charge + and - connections. All I do is plug in the MeanWells, and then plug the two 18-pin plugs, one from each 1420i, hit start on both chargers, and that's it.

Yes, magic smoke will be forthcoming.

It would work if I wanted to break the series connection between the two 12s3p pack, but what's the point? I can now basically charge my whole 24s3p setup at 11-12A and end up with balanced cells, every time. No muss, no fuss.
