Most issues I see with wires and or batteries getting too hot are the connectors and or bullet plugs. The bird cage style bullet connectors are not suitable in 4x setups that pull down lots of amperage. I run the solid type bullet connectors on both my MMP and RX8 controllers and never have had a problem.
That's one thing I forgot to mention... I was running the birdcage style bullets, and had it fail once when they were nearly new, but towards the end of their life they definitely had a weaker connection and I had more issues with them. Now I will only run the solid style bullets. I do still believe that the lower c rating had played a part tho... Because I never had any issues while using them in my 2wd vehicles... Even with the worn out birdcage bullets. To each his own on that topic
