With those kinds of currents, it'll be interesting to see if point of load DC-DC converters become integrated into the motors themselves so as to reduce the wiring requirements for distributing the power to the motors. The batteries will need to stack more cells in series to support this but I wonder at what currents the wire gauge, and hence weight of the wires, become a big concern.
Maybe modern quads already do this?
- halbritt 9y agoWire runs are so short and peak current is so brief that it effectively doesn't matter. Most folks run 14AWG between the battery and the power distribution board. PDBs are generally made with 2oz copper and wide traces to accommodate the current, from there, the total current load is divided by 4, assuming that's how many motors or running.
