Hyperion 7i Wiring

That helped quite a bit for me. No more warm wires and the input voltage at the charger was higher.

However, this will require opening the charger and desoldering/resoldering on the circuit board. I am sure this will void any warranty, so be warned.

Another way to go about it would be to shorten the existing wire to about 2 or 3 feet. This obviously won't change the gauge, but will still reduce the voltage drop, if not as much as replacing the wire altogether.
