I have a TGE Boost Regulator* connected to lead-acid batteries
powering my K3. The boost regulator is set for 13.7V which drops
to 13.3V during 100W CW key down. The device is connected to the
radio with about 30cm (1 ft) of #10 zip cord and PowerPoles.
I have had problems in the past with the screws working loose on
bolt attachments with some cheap Chinese equipment, so there is
no substitute for checking the voltage drop under load,
regardless of connector technology. Fortunately the internal
volt meter in the K3(S) makes a good/look for the problem test easy.
Car stereo installers may be a good source for flexible heavy
gage wire.
Also, PowerPole has some "75A" connectors which are a lot more
robust (and not plug compatible) than the 15/30/45A ones
generally seen.

* Notes on the TGE Boost Regulator:
I have not noticed any RFI coming from it, but my antennas are
away from the house on our 250 foot deep lot, so household RFI
isn't as much of a factor as it would be on a smaller lot.
I got the 30A circuit breaker option, and have popped it on
occasion when running a FT8 frequency with low batteries. I now
monitor the device's temperature with my hand and go QRT for a
while when it gets too hot. Perhaps getting a device rated for
more that 20A might be a good idea.
During manufacture, they scraped all the numbers off the ICs in
the device. My opinion of this kind of behavior can not be
properly expressed in a polite forum.
