larger connectors can reduce resistance in the circuit.
larger guage wires allso reduce resistance.
If you are melting solder your wiring needs upgraded.

that makes no sense to me if the wires are cool to the touch...
the biggest issue I think and have woeked with is bad solder connections..
I clean up all my connections even on my battery packs to make sure the solder job is nice an clean, and it dones make a big difference IMO
